I've read several of the Cobb Discussion thread, but I didn't see what I was looking for. And I did not read the entire thread since there's about 60 pages.

I was hoping to find people's opinions of the differences felt and other dyno results vs. what's on Cobb's site.

Everyone is busy playing with their fuel trims. :lol: I am not even considering it until I see before and after dynos.

Please read the whole thread.

Moderators need to close this.

We don't need another AP thread.

Mods, please rename this thread Cobb AP Dyno results.

Mods, please rename this thread Cobb AP Dyno results.

You can do that. Just edit the post.

actually, delete this thread until at least one person has a dyno to show :P

Good idea on having a Dyno results thread. Feel free to kill this thread.

But it would be good to read some anecdotal opinions on what people think thus far. I checked the Cobb forums and there's really nothing there either. Going through 60 pages on the Discussion thread is too much, especially when the pages I looked at were mostly about fuel trims and other technical data.

I'll contribue to this on April 26th. I have a dyno day set up, 20 cars are scheduled, more then half with AP's.

how many of those are NA?

I think Arizona will have a contribution in the next couple of days also.

how many of those are NA?

at least 4 or 5

Skylee has put his car with the AP on the dyno but no graph. I believe he was running the base map from MM and has not moved on to the more agrgessive maps

Max HP: 185
Max TQ: 139

Hell I got more than that stock!

he might have been on a mustang dyno???
Razz: you did higher on a dynojet

I am at 198/140 already. A this point the RB flash is looking like a better deal. I thas also been proven to work.

heh. How is your statement logical?

It's just fuel and timing. Can the AP adjust fuel and timing? Of course. So of course the AP can do anything the RB does. In fact, you can get a custom map made for your car, instead of a generic map that your car has to adjust fuel trims for.


Furthermore, without a baseline dyno, saying someone has 180 whp means no gains is illogical. Some cars make 170, others make 190 without fuel management modifications.

^^^ yup. No baseline = stupid conclusion.
I'll have some more definitive info after MM, CRH, and I dyno 20 cars in 3 weeks. stay tuned.

My reasoning:

Cobb states that on a close to stock RX8 you can expect close to 10whp. The AP is a great product, and offers tailored tunes for your car. It is perfect for FI, but much less of a value for NA. Team RX8 dynoed the RB flash and got 9whp. The RB flash costs $300 while preserving the cat converter and I dont have to constantly tinker with it(fuel trims). Will anyone get 20hp from tuning with an NA RX8, very doubtful. Only then would a $700 tuning product be worth the effort, risk, and aggrivation for an NA RX8.

Bottom Line for NA cars:

RB Flash: 9whp $300
Cobb: 10whp $700

Here is my Dyno prior to getting the RB flash which I will be ordering soon unless someone can post some Cobb AP dynos that can change my mind.

No it is cool no one is forcing you to get the AP if you don't see the positive effects it allows to give your car then you should not get it. When you ever want to adjust any thing on your RB flash have fun trying to do it. Get the RB flash and have fun not driving you car for a few days but when you get it I am sure you will be some what pleased.

The RB flash costs $300 while preserving the cat converter and I dont have to constantly tinker with it(fuel trims).

There is no need to mess with fuel trims on the AP either. The car will settle after a while. What we're doing is allowing the map to build in the trims so the car has no adjustments to make.


Bottom Line for NA cars:

RB Flash: 9whp $300
Cobb: 10whp $700

You mess out on the fact that the AP allows you to store and switch maps. If your dealer reflashes, you don't have to pay additional fees. You also get the ability for tweaking other params such as OMP flow rates. Or the AP itself as a odb2 reader.


Here is my Dyno prior to getting the RB flash which I will be ordering soon unless someone can post some Cobb AP dynos that can change my mind.

You are correct however, that fuel is fuel. So if the RB flash pushes your car to the limits for NA, the AP would not give you increased gains over that. In a month or two we'll have the street port software out, and then the AP will also become a data logger, and you can modify the firmware maps yourself :)

Is there a missing the point smile?

Dont forget that the AP does more then just flash your ECU. Unlike the RB reflash, you can customize the tune with the AP, the OMP gets increased, the colling fans turn on earlier (how much is the mazsport cooling fan mod and how long does it take to install?) you can check and clear the CEL (how much does a mechanic charge?) You also get a race tune and a stock tune with 1 product, so if you ever remove your cat you do not have to pay another $300 for a reflash. There are a lot more benefits with the AP then I listed and I am very happy I got mine. Just like hitmann, I am not going to force you to get the AP, but if you think about it, it is a very good value and if you ever decide to go back to stock, you just reflash your car and you can sell your used AP and get a large percentage of money back. Try doing that with the RB reflash.

Is there a missing the point smile?

:banghead: :banghead: <---- that one will do

We dyno'ed three cars yesterday. Flashwing's, mine and MM's. I don't have any of the charts. MM will have to post those. But from what I saw with the Cobb AP is an infinite ability to tune your car. MM said he has over 500 maps already. And I can picture having 10 to 20 per car or more.
The main thing is every car is different. Be it the car, the mods, the weather the altitude. What Cobb has done is provided a way to tune your car perfectly for your conditions. You can adjust AFR's every 100 RPM's if you want. Same with engine timing. Watching that on the dyno graphs yesterday made me a believer in what a fantastic unit the AP really is.

someone must post those charts!

no, don't post them. Posting it will destroy the mystery and suspense that has been building up.

What we need is for this to build up to a huge climax, then leave us with a cliff hanger, and a promise for part 2 in a few years.

Sounds like a real familiar scenario around these boards....

the na cars are NOT going to see any appreciative difference in h/p or torque in comparison to the RB flash. It is however a very good tool to have for other things.
The renny is already tuned pretty good.
olddragger

^^^ correct. This isn't going to give any N/A cars a huge improvement in HP, rather it adresses many performance aspects (stft, ltft, afr, temps, etc) that can result in some additional HP and a better driving Renny!

OD: keep an eye on my SoCal Dyno thread.... we should have some very interesting findings in a few weeks. (20 cars in 1 day)

The good thing I see about the AP for us NA folk is that as you have seen many individuals that are not 100% stock are seeing issues with the cobb stage 1 map, the AP allows us (MM) to recalibrate the maps to fix any discrepencies. I wonder if the same thing is happening to people with the RB flash that are not stock. If so how would they know it and how would they fix it? I saw some scary AFR #'s at WOT using cobb stage 1.

ROger that, will be interesting

Easy E beat me to the punch regarding the accessport. I am in the process of pulling some video of the operation of the AP to post up since I've seen nothing with the AP in action on the dyno.

MazdaManiac has my dyno results and I've left it up to him to post the results because he was the one supporting the dyno time and tuning. I will say that we performed a baseline tune and then used one of Mazdamaniac's generated maps that worked with my trims.

We ran an initial run with the stock programming, but the final OEM flash run we did as a baseline was more accurate to the car's true power.

Baseline run yielded approx 183 WHP. A pre-made tune yielded approx 194 to 195 WHP. This was at about 75 to 80 degrees F.

There's clearly room to go because there's additional specialized tuning that could be done on the car to yield more power. Still, for a pre-generated tune I was impressed. Mods on my car are the K&N Type 2, Cat back and test pipe, AP pulley, lightweight alternator and water pump pulleys.

This is certainly a device that NA people should look into. The ability to have your OMP kicked up a notch, adjust fan settings, kill CEL's and also the tuning is well worth the money. Ditch your CAT and you'll open up some opportunities for power.

We want Video Todd! Then we can watch Jeff hack up fur balls. :Eyecrazy:
For the NA the tuning parameters are so wide. You could make a map for every barometer, humidity and temperature change. Amazing the possibilities.

All hail the Access Port. Long live the Access Port.

which "premade" tune was this? stage 1? stage 2?

which "premade" tune was this? stage 1? stage 2?

MM is going to have to answer this question. Neither Flashwing nor I new what Jeff was installing. And I don't think it was a pre made tune/flash. I think he was tuning the individual car at the time. Making new maps.

oohhh. flashwing had said it was a premade tune. ill wait for MM for clarification then =)

oohhh. flashwing had said it was a premade tune. ill wait for MM for clarification then =)

Quite possible he started with one. Whether he finished with one is another story. I believe he was doing some changes on the maps. Only MM knows for sure.
I know I am having them made as we test. Being the only 4 port NA at this point in time to be tested on the dyno.

The tune was tweaked for injector sizing as we found that my injectors are smaller than the rated size. I guess there's a percentage of variance from the factory. In this case the maps were running much to rich.

I'm sure MM can go into more detail. The part I wish to push is I was told that there's still more tuning that could have taken place. I'm in the process of uploading video from that dyno run. It's nothing ground breaking but those who have not seen the AP in action get to see a few things...and of course a few jokes thrown in there as well.

how many dyno runs were done?

Flashwing's tune was, essentially, 1_3a for the '05.
I played around with injector scaling, but didn't do any real tuning - I was working with limited time on the dyno (I was paying out-of-pocket for three cars for my own benefit). I was mainly interested in corroborating the known effects of 1_X and 1b_X on a know intake setup. This wasn't a tuning session.
Putting Easy's car on there was a two-fold operation: proof of concept on the A/T firmware (it works) and a bit of an experiment to see where his 30 HP went.
Unfortunately, It doesn't appear to have been stolen by bad tuning.
Putting my car on there was purely to verify the MAF scaling and injector staging.
None of this was for power information particularly.
Furthermore, I have specifically stated that increased power is an ancillary benefit of the AccessPORT and that reliable tuning with increased functionality is its primary benefit.
We will see if there is any power to be made on the various street applications in a few weeks.

I apologize for misleading anyone by saying it was a tuning session. We did see an increase in power but as Jeff mentioned it wasn't the result of any real tuning, just using one of the flashes he provides.

I have included a video from that day so you can see the accessport in action. For anyone looking for visual proof or just curious to see it work feel free to check it out.

Any dynos yet?

I have a dyno, but the ignition was breaking up, so it doesn't show anything of note.

End of this month I'll have a new dyno run ... but it cannot be compared with previous runs to show "AccessPort improvements" because several things will have changed. So I don't know if I can help this thread much.

Mysql,

Are you gonna dyno it with the mazsport igntion with the correct dwell setting?

no, I sold those coils already. I don't mind getting my engine tuned, but having to also tune my coils is too much. If I had known this was the requirement, I wouldn't have purchased it to begin with.

I still don't understand.

Scott said the Dwell settings would take 5mins to change. :dunno:

Is there is more to this? Cause if so I will go back to OEM coils also.

Yea, i am also wondering the same thing...

Turborx8,
have you ask MM to change the dwell setting for you?
I emailed him few days ago and have not heard back yet..
he's the most busiest man on earth, lol

I still don't understand.

Scott said the Dwell settings would take 5mins to change. :dunno:

I hope the Ignition is not just something that N/A people will enjoy... If its to much of a pain to manage the fuel and the ignition dwell at every dyno tune I will have to abandon them as well once I get ready for my turbo.

I will miss them, in N/A they made a huge improvement.

... the question/ thought I have "is the ignition solution causing any kind of damage to our engines as it is (not Dwell tuned)"

^^ No, not particularly.
The only risk is if you get a misfire on a leading coil under high load.
If combustion is initiated only by a trailing plug under high load, you can get a monster ping, which might break things.

I will have the table modified and sent to Jeff tomorrow! This is simple stuff, Scott

I will have the table modified and sent to Jeff tomorrow! This is simple stuff, Scott

That is VERY VERY good news.

Thanks Scott!

I will have the table modified and sent to Jeff tomorrow! This is simple stuff, Scott

So to speak.
Simple stuff would have been to use coils with dwell characteristics that match the OE coils.
What is NOT so simple is having to prepare "ignition solution" versions of 150 or so calibration sets.

Yeah, that does really suck.

If you want me to be the 1st to test out the new dwell settings, just include that in the maps you are supposed to send me.

If you want me to be the 1st to test out the new dwell settings, just include that in the maps you are supposed to send me.

As soon as Scott lets me know the characteristics of his coils or sends me a copy of the dwell map, I'll get that out.

I'm way out of my league knowledge-wise here, but I'm guessing there is a reason Scott is using the coils that he is. He may not want to share that reason, which is perfectly understandable. After all, he makes his living basically off intellectual property (his designs).

In my opinion, there should be a turbo version and N/A version so that no dwell settings are required to be changed by the EMS.

That would require two different setups entirely.
I think if Scott had realized he was going to face this particular combination of issues, he would have selected coils based on the appropriate criteria.

Cant wait for it~~

If he did, would the upgraded coils add any HP?

While I completely understand the frustration, I think some folks are looking at this the wrong way. The fact that the ECU has mapping for dwell times is AWESOME. It means that, in the really exotic circumstances where ignition systems that don't match the OEM behavior may be required, the stock ECU can still do the job. I know it's a lot of extra work for MM, but he's obviously a glutton for punishment so he's probably secretly doing cartwheels of joy as a result. Otherwise he'd ship the AP's and a set of maps for "supported" kits and leave it at that. Special order maps would cost extra.

I agree.

The issue has been solved and the only problem is that Jeff has to spend more time building custom maps for those that have the ignition upgrade.

Scott sent the dwell settings to him today so I will post back the results once Jeff sends the new maps my way. :)

I'll get something to you tonight.

dont forget aobut me also
should i send you the map again?

Dont forget me too MM

I have a cold air intake in my RX8. I hear it causes crazy problems for the MAF sensor or something of that nature when combined with the AP. But if I buy it from MM he can send me a special map that adapts to the intake? And now i hear something is wrong with the stock coils, or is that just for force fed RX8's? Just need to know: Cold air intake on mine, I buy an AP from MM, out of the box what do I need to do? Thanks much.

The coil issue is with the new mozsport ignition upgrade, if your stock no need to worry. As for the CAI, I have the MS CAI and have had no issues with MM's maps. Though I did have issues with the Cobb stage 1 map.

The thing to keep in mind is that you're not changing anything on your car with the AP. Your hardware that works today, will be used exactly the same once you flash with the AP. The only thing that changes is the map used in your PCM.

So if it works now, it should work after. If not, talk to Jeff and he can fix it.

The FI people had problems because most of our systems used to be MAP based once the car got into boost. MAP mode doesn't use the MAF sensor, so it didn't really matter how our intakes were setup. Once we were using MAF 100% of the time, the airflow across the MAF sensor mattered, and if not setup properly, the car assumed a LOT of air flowed and we ended up with a rich (safe) AFR in boost.

You need screens on your intake before the MAF sensor to even out the flow to prevent problems...some intakes can get away with a single screen...but I think intake flow is probably going to be your biggest problem...and the AP cannot correct for that...its a mechanical issue...

Did any of you guys waiting on e-mails get my requests yet?

Got the new map this morning
will try it out today.
big thanks

MM,
Can you send me the 3V series with the dwell adjusted
the car is too lean with the 5V map and a screen installed before the MAF
. i am getting high to mid 12's under boost with that .
I also emailed ya
Thanks

Sure.
Did we ever run the 5_0 maps on your car on the dyno?

I dont know if you tried other 5v maps but the last one shown on my AP was 5v_6a. I think you made some tunes on that map. The unstable ilding was becuase there was no screen installed that day. I just got a datalogger so I'll log somthing for you to work on~
Thanks

So, why do you want the v3 calibrations again?

My datalogger can only log 5 parameters at a time.
which 5 parameters are most useful for you to look at?

I just installed a screen before the MAF yesterday and with the 5v_6a map, AFR is in 12's under boost and i went back to 3v_0 and its around 11 under boost~

Log these:

RPM
Calculated Load
Lambda
MAF

Since "5v_6a" worked for you, I'd rather scale that map than start over with the v3 stuff.

OK, went out today to test this...I am consistently seeing 12.9 *sometimes* and 13.9 most of the times...

Again running lean and hot...I'll upload pic of the plugs soon...

LTFT is still @ +2...going to reflash to see if I can get it down...

Just got my AP yesterday, and thought I'd post my initial impressions.

Cobb's hardware leaves a little to be desired IMO. It's kind of cheap for how much you're paying for it... granted they did the R&D to make all this stuff work the the RX8's PCM, including RX8 specific settings, and that's not a small task. I had a problem getting my AP talking with the PCM... at first it wouldn't communicate at all. Unplugging the OBD-II connector and then plugging it back in fixed it, but it's VERY sensitive, and still losses communication sometimes. Wiggling the connector sometimes does the trick... I've heard other people have this problem with the AP's OBD-II connector as well.

After I got the stupid thing installed, it was pretty much smooth sailing. I ended up on MM's "1a" flash, and after about a hundred miles or so (I have long commute :Eyecrazy:) the LTFT is at 0, and my AFRs seem to be right on target (although I haven't logged them and done an in depth analysis yet). I'm pretty happy with the way it runs on the new flash. This is pretty subjective, but it feels a lot smoother, especially in the lower RPM range, and also when the extra intake ports open up at higher RPM--I used to really feel the little hiccups in the torque when this happened before the flash. Overall I doubt the gains are significant, but it does improve the drivability (again, totally subjective). Added bonus is the fans turning on earlier... just in time for the Texas summer months too :lol2:

Overall, I'm very satisfied. I would say that if you're on a tight budget to maybe pass this by, but if you've got some spare cash to throw around then go for it... as long as you don't have ridiculous expectations about the performance gains.

Major props have to go out to MazdaManiac for all the hard work he's put in creating the flashes for all of us. He could (read: should) have charged more money to get the AP from him with these included. Bravo sir... the second half or your handle is certainly apt :)

Anyone post dyno's yet?

After June 7th there will be a few.

I just got the Cobb AP from MM today. The "start" file feels pretty good (only had a 10km drive home). Already, the car felt like it had a bit more pep and response in the lower RPMs. I got to drive it on the highway for a bit and the butt dyno said that there was "an increase in awesomeness".

My favorite read out screen so far is the "Mileage". I know from a previous post that the mileage calculation from the AP is off but for some reason I love seeing 26MPG on the screen :) Ha ha ... one can only dream.

I'm off to go drive around and to look at my STFT and AFRs again. Weee!

There are dynos all over the site.
Just none posted here.
Check the various local dyno threads.
There seem to be a lot of Mustang dynos out there, which make owners sad (with stock numbers in the 140 range at times).
But the AP generally pulls about 7 - 15 HP out of an otherwise stock car.
Deleting the CAT and using the AP produces the biggest results.
I've gotten several cars with no CAT, exhaust and intake into the 220 range.

cobb -- 730
hks intake 500
High flow cat 250
total 1408.00

some how 1,408 dollars should give me more than 12.3 whp

enzo set up the dyno at no limit motorsport so they read the same.

any thaughts?

Kind of an odd way to think of it, but not particularly true.
First, those dollars gave you a bunch more things than just power.
Second, people spend $5k to see ~50 HP with base turbo kits.
Third, I've seen people with that intake lose power rather than gain it.
Fourth, you don't specify the ambient conditions in those dynos.
1" of mercury on the baro, 15°F on the thermo or 30% relative humidity difference could be more than 10HP either way on an N/A car.

You haven't ruled out any mechanical issues with the car and you haven't verified that the calibration you are running on the AccessPORT is correctly tuned for your setup with AFR readings.

any thaughts?Just think of how quickly you'll make that money back with increased fuel economy.

my issue is not on the gains... but the gains post cobb instaul.... the car seamed a bit odd after the cobb map... 1. i need a custom mm map... or 2. i just have the wrong map on...

as for conditions...

82 F, hum. 23%

my dyno curve does not look normal no matter how you look at it.

READ THE FIRST POST OF THE ACCESSPORT THREAD!!!!!!

long term -2 right now...
short term -7 to 7

i dont think my problem is fuel....

what about it does not look normal ?

The squiggly lines would more likely be something to do with the dyno - not your car ....
