Yeah, i'd also buy a v1 or 2... Anyone sells v1?

I maybe willing to sell my V1 if i buy the V2, If you want to send me a PM I will keep you updated when he starts selling the V2

^^^ What that guy said. I have a V1 and want to upgrade as well.

I just want to rent one... I work 8-5 Mazdatrix is to far away. My only free time is the weekend. anyone in Socal have one?

I too would be interested in renting one for a few days, would even pay a deposit.

Would anyone want to sell me their v1? I am literally turning away people every week needing compression tested.

Maybe a new GB thread for the v2 should be started, I would def be in!

Come to Vegas

Twisted Rotors has apparently decided to start his own forum:
http://www.twistedrotors.com/forum/index.php?topic=5.0

Good news is it looks like version 2 is moving forward.

I would like to ask for a favor. Any of you guys willing to lend me your TR-01? I will naturally pay for shipping both ways. I'd really like to check my compression without having to hassle with the dealership.

Anyone? Please pm me :)

I will be going to 7 stock and can bring my tester along with me if there is any interest. It is easy to do but you do have to remove your plugs. I've loaned mine to several peeps and while it always comes back in good shape, I always seem to need it for a local when it's gone.

I am awaiting V2 and expect to hear soon.

Phil: if you hear anything about the V2, will ya let me know?
I haven't kept up with this thread much but would be highly interested in buying one of these.

see ya at SevenStock!

I need to check my compression badly. Was going to get BHR to do it at SS but I don't have the money for it. All my money has gone into mods for my car.

I want one too.

Saw a v2 in use. Pretty neat. Think he may still be testing it though. Pretty much every group of rotary guys could use one of these. It was awesome.

Ive been begging socal to throw in $20 each to have one for the group.

They are not that expensive.......I purchased mine and just let the Vegas peeps use it as necessary. When V2 is available I will have two of them.

Your expensive and my expensive are about $200 off from each other lol.

Should I wait on the V2? Is there an ETA?

I really like V1 and it's easy to use. V2 appears to be an upgrade. It was supposed to be Blue Tooth compatable but that has gone by the way side. I am sure he will post when ready to sell but if I get any information I will pass it on.

The one I saw had working bluetooth and it transmitted to his laptop.

Oh wow, is there software to make the data into a graph or anything? I want.

Yes there will be a Bluetooth option on the V2.0, all updates are shown at

Last post I see is August 12th where he says that Blue Tooth will not happen in this offering.......If you know something else then I will stand corrected.

The test units had Blue Tooth.

QUOTE: Sad news from the v2.0 camp today. After some real world testing at my local RX-Club of Houston meet I'm going to have to put the Bluetooth on hold. I don't know if it's this particular BT module or what but it's just not talking fast enough. Too many readings are getting skipped over while waiting for the BT module. This problem gets more and more apparent as cranking RPM increases.

I'm not saying BT will never be implemented but for now I've got to put it on the back-burner. What's that business saying, "Manufacturing costs shrink as design costs soar."? Yeah, I've got to get a new tester out on the market. I know there are way more people who just want a tester and could care less about Bluetooth. UNQUOTE

Yep that was posted right after the meet I was talking about.

I think I'm just gonna go to mazdatrix they charged me $50 last time.

I think I'm just gonna go to mazdatrix they charged me $50 last time.
At that rate you could buy one with a few of these tests..........What causes you to think you need to test so bad?

Yea you could charge people 25 and pay for the tester in no time

I rebuilt my engine about 3k ago i want to see how shes doing.

Any news about the V2?

And what about the different reading between V1 and a Mazda tester? anyone found out if there was different readings?

With my limited experience with the Mazda tester (only watched it being used) my readings were within an acceptable tolarance . The Mazda tester seems to have several ways to change the readings so it seems to me that it is only as good as the operator. The TR-01 requires that you keep a fresh battery in it and use the correct correction factor for your vehicle.

Lets just say that I use them heavily, I am one of the offical testers of the V2

This was a Compression Test OFF at one of our local meets, everyone puts in 5 bucks to play, the person with the Lowest compression gets the pot. Kinda like a sorry about your bad luck here is the start of a rebuild fund. This was the first one and had a decent outcome.

LOL thats the funniest idea ever haha

it's one of those, "you always WANT to win, but do you REALLY?" moments.

So when is this available? Can I be a "tester"?

any news on V2 availability?

^ Yes, any news?

I am curious too, been looking at this for a little while

Bump.

looking for an update

Twisted Rotors has his own forum. I went on the forum and found the last post from him was December 4th but no mention of when we would see version #2. Also left a message to please update us.

Find out for yourself!

Nothing new posted this year. I'll try to go to the next RX7 meet and find out something.

are we ever going to see Version 2.0? :(

I have seen what I believe to be a V2.0 (or at least V1.5) with my own eyes. I'll try to get some info.

i also want one tester from here in Spain.

When would be available or where can i buy one?

This guy doesn't wants our money? ;)

I don't normally come to the RX8 forums but RX7_Nut told me the other day that I had some antsy potential customers over here. That was definitely an understatement!
Thanks to those who have been posting up the newest information from my website here and just to reiterate:
No, I'm not dead.
Yes, v2.0 is still on its way.
No, I don't have a ship date.
Yes, I will do a "Group Buy".
My website has the most "up to date" information.

Honestly the past 4 months of delays have not been due to testing or development of v2.0 but in waiting for a key piece of machinery that I need to machine the cases. v1.0 was so labour intensive that I couldn't keep up with demand. My goal is to not have that problem with v2.0.
Thanks for all your interest!

Me. me, me. I wonder what shipping would be.

Sold..

I'm looking for this compression tester (used) at a reasonable price. Any sellers? Please PM me.

Thank you

Seems these are no longer available. Anyone want to sell theirs?

I really need to buy one as I have 2cars here and don't want to use a piston tester. Anyone else want to sell theirs?

I'm not selling mine but I have loaned it a couple times, if interested I require a $500 deposit that you get back (except shipping costs) after you return it to me

I confirm, the site is infected I got the malware
TWISTED need to fix your site

Hey everyone,
Thanks for the heads-up about my site. I'm looking into the problem now. I could use some more specific information though. Like what antivirus software you're running, which page on my site is causing the error and the exact wording of the error. I am much better with hardware than software so I can use all the help I can get! lol! Thanks again.

Any updates on the tester?

I'm waiting for the release of v2.0

I get suscribed to this thread waiting for news.

A few days ago I registered on their website to see what's new.... awaiting of your aproval!!!

I signed up for updates over a year ago, never heard anything from them.
I know he's made progress since then as he's posted here and on his site but I'm still waiting for Version 2.0

with a lot of cars approaching the 100k mark, I'm sure these will fly off the shelves for people wanting to keep an eye on compression before their warranties come up....

I was one of the lucky ones that got a version 1. I wanted a version 2 and was supposed to be one of the testers but I have not heard anything lately.

I think we are many people already we want a v2.0.

I wish that each fo us can buy one. :fingersx:

Anyone got one to loan? Seeing as how who knows when the v2 is coming out and being I just hit the last stretch I'd rather be safe than sorry lol, someone shoot me a pm :)

I think Mazda North America must have put a hit out on him.....

Today I received an e-mail:

TR-01 Rotary Engine Compression Tester v2.0 Pre-Order
The time has come! I am beginning the TR-01 v2.0 Pre-order. Pre-order pricing for the TR-01 v2.0 is $300, normal pricing will be $350. Please note that this is a pre-order and that I do NOT have any testers to ship at this time.
By purchasing during the pre-order you are getting your tester at a reduced price but you will have to wait to receive it. This offer will last for 45 days, ending September 22nd. This is very similar to a Group Buy but without the requirement of a minimum number of people. Everyone gets this deal regardless of how few or how many people buy.
Testers will begin shipping September 12th in the order that they were purchased. Please visit my website www.TwistedRotors.com to purchase. More pictures and information will be posted on my Forums soon and as always please feel free to ask me any questions. Thanks!

-John

I sent in my payment for Version 2 today..........

Phil, you Baller!
sooooo tempted to send money right now.

I'm not gonna miss out on this one.

I'm curious to see what is new with the Version 2, I just spent some time on twistedrotors.com but there's no 'final specs' anywhere.
I know for a while the device was to have Bluetooth but that didn't work as well as he wanted so last I heard that was scrapped.

Read something about USB...

I'm also wondering about the ability to put a custom message on it when it boots up as the V1 has.

................................................
I'm also wondering about the ability to put a custom message on it when it boots up as the V1 has.

If it holds true to what he and I talked about, yes the custom message option will still be there. I would leave the explainations to Twisted Rotors. I know that the first option worked very well and I know what I expect out of V2.

You could always wait until I get mine.............

Ok ... I just went to twistedrotors.com

I wanted to sign up (aka buy) for the pre-order special .....

I have NO idea how and who to send money too ....
His thread provides no details about signing up or buying ...
Or am I blind. ..... could be

Oh and I know he has a paypal address in the first post of this thread. That hasn't been update since 2009!!!!!!!!!!!!!!!!!!!!!
I'm not sending a paypal to that address until he updates the information in the first post ... or I see it in his new forums.

you have a v1 dont ya phil? would you be interested in selling it after you get the new one?

Yes I do have a V1. No I don't think I will sell it right away.......Maybe down the road a bit.

I got a shipping notice yesterday! It's on the way ...

So did I.....should see it soon

So, who's going to get theirs first? :D

So, who's going to get theirs first? :D

Answer: me! :D:

Very nice build; can't wait to try it out!

It came in Friday but I've been too busy to give it a try.....

Got mine too. Comes with battery, but no instructions? Wonder where they are?

I'm fairly certain the v1 instructions largely apply, although I am curious about the USB port; is it for downloading logs, updating firmware, or both? Unfortunately the forum is currently down @ TwistedRotors.

^ Well, I just parked my 8 for the winter, so there's not a huge hurry. But I'm curious to see it work, and kinda expect a line to form as soon as MRC locals and the Windsor contingent find out I've got one.

Instructions gathered together earlier in the thread : http://www.rx8club.com/showpost.php?p=2985899&postcount=46

EDIT : I'm gonna try to do a test after work tomorrow if I can get around to the ESS in the dark.

Go mine as well. What's the USB for?

Those are the instructions for Version one........I was hoping for V2 instruction so I understand the computer hook up..................Maybe there was something I missed in his forum.

so phil, you want to sell me that v1 tester yet? lol

Go mine as well. What's the USB for?

To upload MP-3 files? :ylsuper:

WOOT!!! Mine just arrived and the batteries are INCLUDED FTFW!!

To bad I'm not going to get a chance to try out for awhile.

Have any of you guys tried it yet?

so phil, you want to sell me that v1 tester yet? lol

Na I don't think I am going to sell it. If I change my mind I will let you know.

Have any of you guys tried it yet?

Yep! Spent the afternoon playing with it. I bought this car with 8,800 miles on the clock June 2009. It's never been driven during winter, but only been parked for about a week this time. The PIA factor is getting access to the eccentric shaft position sensor which pretty much requires pulling the airbox out, as well as pulling the left front wheel to reach the spark plugs easily. Otherwise, all straightforward. I did one measurement dead cold, then warmed the engine and repeated. Partway through, I hooked up a 10A charger which improved the rpm (I'm using a smaller than stock battery). I also learned toward the end, it's best to crank for a full 10 seconds which seems to make some difference on the front rotor readings.

Raw Data (pressures in PSI):

OBDII = 50 deg F
Front: 103 98 95 @ 228 rpm
Rear: 101 103 104 @ 232 rpm

I'm not exactly delirious with joy over these numbers. It would be interesting to have the dealer do an official test for comparison, but that's not gonna happen for many months. I'll certainly do another check at the end of next season for comparison. :sadwavey:

^ Well, I just parked my 8 for the winter, so there's not a huge hurry. But I'm curious to see it work, and kinda expect a line to form as soon as MRC locals and the Windsor contingent find out I've got one.

Well, my car is parked for the winter so I won't be able to get in line unless you go south of the border. Maybe I can lure you to Windsor with your handy new product. I sometimes wonder how my build is holding up. My 8 is my only car (out of 4) to still have it's original motor in it. Go figure.

Raw values :
Front : 107, 102, 99 @ 295 rpm
Rear : 108, 108, 105 @ 301 rpm

Normalized to 250 rpm :
Front : 100.40, 95.71, 92.89 @ 250 rpm
Rear : 100.06, 100.06, 97.28 @ 250 rpm

Meh. Technically out of spec, and I haven't really had any problems ( @ 89k miles ). I suspect with this close of values that trying to get a warranty replacement might be a challenge at this point. It's a little annoying actually knowing, now that I realize it.

On a side note, I forgot to reset the ESS before first firing it up, and got a p0335 code; does this clear by itself?

For what it's worth, the fox calculator I referenced above, doesn't seem to function correctly. First enter, 100 psi on the 3 faces and 0 ft altitude. It gives a corrected value of 105.6 instead of the 103.9 that would come from the Renny correction factor. Second as one raises the altitude, the corrected value goes down, not up. In other words, if you measured 50 psi at 18000 feet, the corrected value (at sea level) should be about 100 psi, not 25 psi as it works now.

Something's amiss. It would be quite nice if TwistedRotors would bring up the website and give us the scoop himself.

Doing another series, and making the calculation "correctly", at least as I understand it right now, gives:

F: 114.0 110.4 106.4 psi ... avg: 110.3
R: 117.1 112.0 115.1 psi ... avg: 114.7

Thanks for the update HiFlite

Bump.
Finally got around to doing this .. and as I suspected it's out of spec.
I imagine I've been out of spec for the last 40,000 km's that's when I started noticing hot start issues.

Front at 191 rpm
70 67 67

Rear

Meh .. oh well .. time to get a new motor ordered/shipped while I turn up the bewst on this one!

There's an ANdroid App called RX8 Compression, does the normalizing for you.. pretty neat.

Like I said before, I bet so many people out there are running low-compression (under spec) engines without even realizing it... poor fuel economy... random hot starts.... no CEL, never stalls....

There's an ANdroid App called RX8 Compression, does the normalizing for you.. pretty neat.

Yah man thanks ... I do have that but truth be told I don't trust the numbers.

If I go by the results given by the Android app I'm really really really low ...

What I find confusing is why do we need to normalize to 250 rpm when we are clearly given graphs that trend from 200 rpm (150 rpm in one graph) to 300 rpm.
Why fucking bother with a graph if we also have to normalize to 250 rpm ... if this is the class its much easier to say ... Adjust for altitude and normalize your values to 250 rpm, here's the acceptable range. <full stop>

The graphs lead me to believe you do not need to normalize ... just compare your rpm value and psi on the graph and see if you fall in the acceptable range.
Especially as one of the graphs in not completely linear http://m.rx8club.com/attachment.php?attachmentid=151946&d=1266716801

WRT, my post #376 above, the Foxed calc seems to have been changed since I posted and seems to give better results.

The twistedrotors site seems to still be semi-dead, however.

The problem with the stupid ass chart is that it's not clear which lines the values point to. Alsoas HiFlite999 mentioned it's not a straight line, someone must have calculated the formula for the curve (hopefully they have done it properly) and used that to normalize the value.

The only reason we normalize is because instead of relying on a graph to figure it out, we are given AS A FACT, numerically what the compression pressure values should be at 250 rpm. We're simply scaling "your curve" to the 250 rpm value to draw a comparison. That's all. Mazda did not say what the compression value should be specifically at 300 rpm, but they did say what it should be at 250 rpm and we're going by that.


case in point, if I told you to look at the graph only, tell me what the compression value should be at precisely 287 rpm, would you know? The graph is so vague, it sucks at doing so... try finding where your value is at 287 rpm on the x-axis, and then try determining what the pressure value is on the y-axis from the graph.

The graph sucks period...

I find the excel spreadsheet pretty good, and the android app is good too (allows various units)

Raw data ------------
Front at 191 rpm
70 67 67 psi
Rear at 196 rpm
73 69 68 psi

-------------------------

Normalized to250 RPM using the foxed.ca application
Front
87.55 83.80 83.80 psi

Rear
90.07 85.14 83.90 psi

Using this link to convert psi to kpa http://www.sensorsone.co.uk/pressure-units-conversion.html

Front = 603.636 : 577.781 : 577.781 kpa

Rear = 621.011 : 587.020 : 578.470 kpa

Now compare these values to the 3 different graphs
1) http://www.rx8club.com/showthread.php?t=229440
Front rotor = Epic Fail : Epicest Fail : Epicest Fail
Rear rotor = Epic Fail : Epic Fail : Epicest Fail

2) http://www.rx8club.com/showpost.php?p=3663977&postcount=6
Front rotor = Pass : Fail : Fail
Rear Rotor = Pass : Just Failed : Fail

3) http://m.rx8club.com/attachment.php?attachmentid=151946&d=1266716801
Front rotor = Bad Fail : Epic Fail : Epic Fail
Rear rotor = Fail : Epic Fail : Epic Fail


Clearly after normalizing to 250 and comparing to the three graphs there are different tolerances. I guess I have to hope RIWWP is as always doing an excellent job at his due diligence and his graph is the correct graph.


Now I'm off to try and makes sure the Normalized values are being calculated correctly.

EDIT ----- Had the Tolerances given to me by RIWWP

Compression pressure
(kPa {kgf/cm2, psi} [rpm])

Standard
830 {8.5, 120} [250 rpm]

Minimum
680 {6.9 , 98.6} [250 rpm]

Standard difference in chambers
Within 150 {1.5, 21.8}

Standard difference in rotors
Within 100 {1.0, 14.5}

Excel Spread sheet results normalized to 250 rpm

Front 620.92 : 599.92 : 599.92 kpa
Rear 627.98 : 600.98 : 593.98 kpa

Android App (Note I've read the thread for this app and to me it's not clear what the input values should be and what the app is actually doing. Therefore entered non normalized raw psi numbers and converted to kpa for final results)

Front 484.081 : 463.397 : 463.397
Rear 504.627 : 477.048 : 470.153

Clearly the Android App doesn't work or is doing something different or I'm not entering the right data for the input requests.

So what other value could you enter, well the normalized value?

EDIT --------------------------
So I just compared the Android values to the Excel App and the Android values are exact same as the unadjusted kPa compression values in the Excel App. So clearly my version on ICS is not doing and normalizing to 250 rpm it is ONLY converting the PSI (my input value) to kpa

EDIT EDIT -------------------
I just re-entered the values this time using kpa as the input value and it gave me almost the same values as the Excel app .. actually a point or 2 higher. I believe the Android app is not converting PSI and Normalizing correctly (bug my just on ICS).

LOL well said .. I get it now .. gollee u sure make learning phun footman

you're cranking low eh? need new battery?

Are you within warranty for new engine?

you're cranking low eh? need new battery?

Old style starter.

It's a brand new battery ... brand new as in bought it yesterday Red Top 34/78

EDIT ---
Actually the first time I did the compression test I had the opposite spark plug installed that lowered RPM to 180.
For these results I removed both plugs.

Are you within warranty for new engine?

LOL you're soooo funny.
2005 with 84,000 km's

I believe I am but who would take it.
I'm not even sure I could put it back to stock.

WCS, I've seen the 3 different charts you posted and here are my thoughts.

Two of them don't mention what engine it's for, maybe the poster cut it off the picture, but regardless no mention of the fact that the chart is for the Renesis 13B. The same two charts show only 1 curve. Now is this curve the "brand new engine" curve (standard), or is it the mimimum cut off? No idea.

This leads me to think that the best chart is the one with the two curves showing standard and minimum. This same chart also clearly says 13B-MSP (Renesis engine)

http://m.rx8club.com/attachment.php?attachmentid=151946&d=1266716801

This is also the same chart I have at home in the RX-8 Field Service Manual (FSM).

Also using this graph it's a little easier to see that at 250 rpm, the minimum acceptable compression is around 680 kPa

What the? How come you use 34/78 RedTop? That makes the connectors far to reach.... how come you didn't take Group 35?

Put it back to stock WCS, then get new engine... hurry before 2013!!! (8 year/160,000 km)

Actually I wanted the 34R but it was on back order.
Dude, maybe you didn't know. I'm boosted, my battery has been relocated to the trunk. I could put a fork lift battery in there is I wanted lol.

Put it back to stock WCS, then get new engine... hurry before 2013!!! (8 year/160,000 km)

I have all the parts except the exhaust manifold which I technically have but the O2 bunghole is fucked (no pun intended)

I've cut some sheet metal around the intake area and modified the lower air deflector around the radiator ...

I dunno maybe

New numbers in after installing new upgraded starter.
Wow ... just wow ... car starts instantly even after hot I tried a off/on and it fired right up.
Unfortunately the numbers are not a lot better.

Using foxed.ca compression app, my altitude is 1500 ft
Raw Data ------
Front @ 320 rpm @ 178 F coolant temp
101, 100, 99 psi

Adjust for Sensor dead space 1.039 and altitude 1.0417
109.3, 108.23, 107.15

Rear @ 289 rpm @ 183 F coolant temp
100, 100, 95 psi

Adjust for Sensor and alt
108.23, 108.23, 102.82

Normalized ------ using Android app
Front = 91.34, 90.27, 89.19 psi

Rear = 97.87, 97.87, 92.46 psi

Next step --- ATF trick then re-test

Driving the RX-8 is never about the numbers, it's about the experience and the experience of driving it is the best selling point in favour of it. If you drive it and there is a heart beating in your chest, I believe you WILL buy it. The tragedy is that too many talk themselves out of even trying it because of the numbers.
I would also display a final average while still displaying the instantaneous data. The average would discard the first two and last two readings. The fact that the last data being displayed appears to include the rundown of the engine raises some questions regarding its ultimate accuracy.

First thing, what does your first sentence have anything to with this thread?
Did I miss the post where someone was not buying an 8 because of numbers?

Second:
I think I understand what you mean. I don't know if or how to get the instant numbers from the TR-01v2.
The procedure has you cranking the engine for 5ish seconds so you are going to have a large set of data. So I'm guessing this device only displays the final average compression values of the 3 chambers <mmmmm>

Ok, so continuing on your suggestion if I can get the instant numbers it is the first and last number of the instant numbers I would discard (for each chamber) then average the remain data.

I will do some digging and see if I can get more out of this device. Anyone know what that usb cable does?

Would someone explain to me what rundown is?



Those are the instant numbers and the normalized values.

You want to average the compression value for all the chambers ...

Going with the
