OK, you might have noticed that I moved this thread to the Aftermarket/MazdaSpeed forum where it really belongs.

So, here are some dyno runs we recently did on a local DynoJet.

Before somebody goes off about how low my stock runs are, please remember we are at about 3,000 foot ( 1,000 meter) altitude.

Thanks all, and if questions arise email me as you like.

Oh, if you wonder why the bottom index is in miles per hour rather than rpm, that is because we did not hook up to the ignition rpm.
We just did the dyno calibration to fixed rpm's and then adjusted the output to scale it.

Both runs were done the same way.
We did 5 runs in total, and show the best of each condition here.
So, any power readings that are significant are mostly about the differences.
In all cases i brought it up to 2,000rpm, then went WOT on the run.

The same calibrations,adjustments for altitude, temperature, baro pressure, etc were used on all runs. We calibrated for SAE horsepower, so for the Kilowatt crowd the readings are:
Stock: 125.72KW (rear wheels)
Stage1: 143.54KW (rear wheels)
If one were to take Mazda's claim of 238HP at the crank, and scale power down for altitude then we see 222hp at the engine on the stock run, and 253HP on the one with Stage1.
Accepted scaling for 3,000 foot altitude is about 6.5% less than sea level readings.

Scale that back to sea level and we get crank HP of 269

Woh... 270 BHP at sea level? Woh. :D

So are you prepared to post your GTech stuff yet? Really want to see those performance numbers! As I recall a while back you ran a GTech-measured 13.78s 1/4 mile...

brothervoodoo

Well, CZ stated using Mazda's claimed number of 238 and then making the necessary calculation for altitude, etc. We all know how mazda's numbers work. Either way, what is important is the power to the wheels and I really like what I'm seeing. This is great work CZ, make sure not to forget about me.

Very interested in your products. I've used similar piggyback tuning software on a blown 2000 Mustang GT. Would you happen to have the A/F curve for the dyno you posted? If so, please post.

Also, I've read a little about your stage I and stage II products. Do you have any additional information posted anywhere?

Please keep up the development; I'm definitely a client once you get the product to market.

Everything you ever wanted to know about the history of the development of this mod can be found here, and info on the unit that came out of all the development can be found here. Reviews by the "Beta testers" of this mod can be found here.

Hope this helps.

canzoomer

Exactly right.
I was being a bit sarcastic.

I do not believe in a million years that the engine makes 238HP stock on an engine dyno.
Let's do some basic math.
If the engine does 238, and we get around 176 at the crank ( sea level corrected) and that is on a dynojet (considered the most optimistic dyno), then we are seeing a driveline loss of 62hp.
That is 26%.

I think the real number is about 15% to 20% driveline loss, probably closer to the 15% since the RX-8 is not driving a power steering pump.

That means that the crank power is at around 210 to 220hp
Stock.

And with our tuning, 236 to 248hp at the crank.
Hmmm, those numbers look familiar.. As in where they should be.
Or, at least where they belong before the engine is de-tuned for emissions.


Thanks to OMicron for looking up those links, I really dread having to do that one more time.

canzoomer

Sorry. Flushed those.
Intended to do some more, as I was using the original firmware on the GTech Pro, and using metric settings.
There is a buglet in the older GTech Pro Comp firmware that corrupts the torque figures in metric readings, so I re-flashed the device with the new firmware, which wiped the stored runs.

Then the weather went for crap again, precluding doing more at the time.

When we get our next warmish spell I will do some more.

By then I expect we start to get test readings from others as we have started shipping out units to warmer climes than here, and by the end of next week there will be quite a few at their new homes, being busily installed.

I really want to see some of the sea level numbers on this.

Genom

I'm as sea level as you can get considering my driveway floods everytime there's more than 1 inch of water (2 miles from the beach, so no water drains at all).

And the weather has been GREAT for driving. Clear, sunny and cool (mid 60's, 80% humidity). Enjoyable compared to the usual 95+ and 100% humidity.

It will also be interesting to see how the map repsonds to those temps/humidity. Unless those wouldnt affect too much? I dont know. I'm rambling, I'm excited and I still need top read up on a lot of stuff.

Barnes and Noble, I am your bitch!

RX8MAN04

HAS ANYONE INSTALLED STAGE I YET.HAVE'NT HEARD ANY FEEDBACK ON IT.

brothervoodoo

They are just starting to ship... stop YELLING!!

Jag

A few people that live around Canzoomer have tested it, like myself. Look on Canzoomer's forum for a few reviews from those of us lucky enough to try out the stage 1 ecu mod.

XDEEDUBBX

the one thing that would really impress me if someone shot a video of an regular stock rx-8 vs another rx-8 with the stage one installed running against each other on the 1/4 mile...anyone else would like to see this???CANZOOMER..can you do this please?

RX-Nut

ooh.. that's a cool idea.. hmmmmm

had the pleasure of meeting Maurice on the weekend, and we had a good long chat at his place. Very welcoming individual, and we chatted for over an hour while I looked at the stage 1 mod. He even popped the hood of his car to show me just a few things on the install. Needless to say, I have purchased one, with not 8 yet ! (doesn't arrive until March).
Anyway, he commented on the stock performance, as well as stage 1 comparison. I asked him about the G35C comparison, and he commented he had a few runs with a 350z track pack, with his stage 1 kit installed, and the 8 was neck and neck. The z would pull down low, but the 8 would catch up due to higher revs. Basically back and forth with no real winner. Sounds like enough power to me!

Also had a full pulls with a VW GTI with a modded chip. I drive a 1.8 Turbo Jetta, and trust me these cars with a chip are a rocket. My car stock has been neck and neck with my buddies G35C? But with his stage 1, against the VW GTI modded (lighter than the Jetta), he was even in the 1/4 mile. Bottom line, the mod gives an already great car that little extra something it was missing !

Broker73

Bottom line, if he is keeping pace with the 350z easlily with his stage one mod, 0-60 comes in under 6secs, and the 1/4 mile 14secs or so. He pulled 13.8 but with 17' winter ties, but still a great time. (g-Tech of course for those who want to bash)

Broker73

sorry, one more thing, the 350z Track pack test numbers show a 0-60 in 5.4-5.5secs.
Hello stage 1 !!!

Genom

Once I get my unit, I am sure I can get another 8 owner to go to the strip with me and do a side by side. Say we both launch at the same RPM's and just see how it goes.

RX8on19s

Just let me know when you get it so we can race and post a clip.

I can't seem to find the info about how much it will cost to upgrade to stage 2 once we have stage 1. ANyone know?

Also how will the firmware be upgraded- will I need a laptop to do it or will be have to send the unit back in?

Luckily I snuck in under the wire with my payment and got the pre- release price- I don't even own an 8 right now but knew I would get one to replace the one I traded back into mazda (for low MPG) I'm sure Maurice is happy to have my money since I paid via paypal- wonder if that will get me bumped up the list?


Also what was the final word about breaking in the engine - should I wait before installing stage 1? I want to baby it even more for the first 1000 miles this time around after reading someones post about really letting the seals set - meaning baby it at first then drive the sh#t out it for the rest of the vehicles life....... hmnnn should I give it 2000 miles? SInce I had 4 months with my first 8- my curiousity aboyt what the car can and can't do has been satisfied- though I can't wait to see what stage 1 does....

tommy12g

Miami guys (Genom and RX8on 19s) Call me when you get it i want to definately be there for it!!!

brothervoodoo

Anybody feel free to jump in and correct me.

• Go to canzoomer's webpage, which is just starting up. There you can pull down the latest price sheet. Prices for stage 1 are updated, as well as 'estimates' for the other stages.
  http://www.canzoomer.com/
• You will send in only the ROM chip in exchange for the stage 2 chip. You won't have to pay full price to upgrade from stage 1.
• No need to wait to put in stage 1 before breaking in engine. The mod does little of anything in low RPM's. So you won't be taking advantage of the fuel re-maps or high revs in break-in mode anyway. 1000 mile break-in is more than enough IMO.

RX-8 friend

To upgrade to Stage 2 you have to send in the Stage 1 module. There are no removeable roms. We will have to rebuild the unit (probably just exchange for one already done). Add wires etc. Otherwise you got it right.

emailists

So that means for street use I'd want to order the CZmidP-4

for $774 US? BY ordering that kit (when available) how much more will it cost to upgrade the ECU module to stage 2? I guess it's OK if you don't know that yet exactky since it's not even avaialble.... Also any idea how much should it cost to get the mid pipe and cat installed?

I told my dealer today about all this ECU stuff going on- he was very excited- he's a Porche driver and though the RX8 was very close in many ways to the 911- just down on power (which dissapointed him becuase he liked the car so much...) - but it seems the gap will be closer and closer.

meeh

Sorry for my ignorance on the matter... I don't know much about the upgade procedures for aftermarkets parts. My question is. If i waited can I just go directly to stage2? It's the same ecu piggy back unit with different mappings? Is it off road use only case you'd have to get a straigh pipe (removing the cat)?

success07

Well, I must say that Canzoomer has done it!! Maurice, I applaud your work!! I received the unit a week ahead of schedule which was a very pleasant suprise. 8am this morning became X-Mas all over again, but this time Santa was wearing a purple hat that said FedEx on it. :D

I had posted on several threads that the Stage 1 that I received didn't have a On/ Off switch, which CanZoomer indicates is there in the 'installation thread'. Nobody responded to me so I said "screw it" and installed it anyway.

I installed the Stage 1 this evening and the directions were right on target. It took me roughly 45mins to do. That of course is do to reading the directions over and over again so has not to miss anything. The biggest pain in the butt was pinching the two little pins on either side of the ECU cover. I essentially just jammed a flat head screw driver in there and pryed it off that way instead of using plyers like it was documented in the instructions. Once I finished, I started the car and turned the wheels all the way to the right and all the way to the left, which gets the DSC light to stop flashing. The traction control light continued to stay on though until I turned the car off and then turned in back on again.

I let the car warm-up for 5 mins, while I awaited the 'switch response' from the forum. Finally, I grabbed my girlfriend and said "let's go see what this thing can do."

I accelerated at normal until I hit the on ramp where a nice, wide-open freeway awaited me at 11pm tonight. Then the fun began. Mind you, I've never done anything like this (meaning engine mods) by myself and with 'no switch' I was a little apprehensive of what would happen next.

What did happen next was amazing!! I hit 5k (or there abouts) on the tach and she took off like a bat out of hell. She threw my girlfriend and I back in the seats and leaped forward like a panther on its prey. I shifted into 3rd at about 8k or so and again we felt our weight hit the back of the heated seats. It's only about 20 degrees right now so yes the butt warmers were on. By the time we finished going throught the gears we had passed everything in sight. My girlfriend could only stare at me with this goofy face. She thought that at 5k, that I was pushing the gas pedal down further because of the leap the car took. I told her that I had it mashed the whole time and that the new ECU was making the car do that. It blew our minds!

I took a 23 mile jog doing all kinds of cruising and accelerating to get a feel for the new ECU. I noticed the strongest pulls in 2nd and 3rd gears as well as a solid pulls while cruising above 80mph (obviously when rpm's are higher). I went through 1st gear much faster than previous times with the same pop at 5k as I felt in gears 2 and 3. I really didn't get into 1st too much but it was drastically improved.

I must say this also. It could be that all of this is just overwhelming but I thought that my RX8Store Exhaust sang a better tune in the upper range of the tach. As I have wrote before, it sings a strong and melodious tune but now it has an even sweeter sound that begs me to run this car to its limits!!

I will head over the RX8Store this weekend to get some time in on the dyno, if Jason is available. I will report the results ASAP.

I'm going to get into alot of trouble with this car. I can just feel it. :D
