I want to know how the different revisions in the software can cause maps to vary so differently...but from my understanding...no matter what version software the maps were made on...they function the same regardless of version of AP firmware...
I hope this makes sense...
like If I loaded up a map onto my car with say AP firmware x and logged it...then 2 weeks later I uninstalled and updated AP to firmware y...reinsatlled same map...it would give me basically the same logs (maybe with different ltft)

Good question.
This is what I sent to Christian at Cobb:
This is what I sent to Christian at Cobb:
With regards to 1.6.3.33 – It is doing something really strange that I can’t put my finger on directly, but the net effect is wildly oscillating AFRs and fuel trims.
Calibrations compiled by that version behave as if the MAF curve is completely screwed up, even though it looks normal in the software.
I verified this by creating two “builds” of the exact same calibration – one using .33 and another using .31.
The .31 calibration behaved normally while the .33 calibration lost its mind.

I guess I'm being paranoid but since my AP was just recently sent out on Tuesday and you also just discovered this 'bug' Jeff, do I have to worry that the base maps that you sent with mine might have been compiled on this flawed firmware?
My STFT changes rapidly when I'm on the throttle but once I'm off it settles back down to 3 or so and then a few moments later works its way down to 0 and stays there.

Hmm this is interesting... Recently i turned back to the base map and followed the instructions.. and the LTFT was at -1 and STFT -0
right now its set at -2 and STFT -0, 1
i didnt change to any other map.
But my maps are from last april whne i baught the cobb from MM
Try installling and see how the FT look?? MM said itll just run really rich. but just keep a look on the AFR's
right now its set at -2 and STFT -0, 1

Hey jeff i was lookin at the custom map you sent me and i saw that the file type is different than the ones my AP manager accepts. I couldnt save or open the file using my AP manager and i think this is the reason. I have installed the most recent version and still nothing. The file types that are supported are .ptm and .stm. I think that its are reffering to the ProTuner Maps and the StreetTuner Maps. So it seems like either you have a newer version of the AP manager that supports the file .xls or i have no idea whats going on. any ideas...????
thx

The maps regardless of what version it was compiled on will work EXACTLY the same on any cobb AP regardless of it's firmware.
If you got a map MADE by the particular version of the tuner software then it'll be all screwed up.
And what you are telling us with STFT and LTFT is normal...although STFT is useless after like driving a block or two with any map loaded on.

Cobb broke the software again.
Last week, I was give v1.6.3.33 to replace v1.6.3.31.
Apparently, anyone that got a calibration built with that version now has wildly gyrating A/F and fuel trims and is extremely rich under load.
For me, it took a perfectly good, extremely fine calibration and made it into trash.
So, if you got a calibration over the past 5 to 7 days or so, be careful. It won't break anything - its extremely rich under most conditions. But you could have flooding or something similar.
I'm going back and rebuilding anything that I made in this time frame with .31 again.
Hopefully, there is nothing underlying that is now screwed in the data.

Hey Jeff.
Charles is going to send out my BHR coils on monday. My accessport maps have the dwell settings for the mazsport ignition solution.
Should I contact you for an upated map so that I can get my dwell settings back to stock or should I leave it alone?

However, the v.33 that I received was beta, so you should be OK.
Because of what I do here, I'm always working at least one version ahead of release.
However, I'd suggest going back to the OE dwell.

As long as they follow the guidelines for how the MAF tube should be, it will work just fine.
Why anyone would waste time designing an intake at this point is beyond me.

You have probably posted this many times already, but how should the MAF tube be?
I figure if they can replicate their 9whp from the 350Z to the RX8 (which might not happen) it could be a good product depending on final price.

They will have to beat the AEM, which gains nearly nothing on its own, but can account for 12 or so with the right exhaust and tuning.
They won't.
The MAF tube needs to be as straight as possible (their bend isn't an issue, I don't think), with no transitions in size a MINUMUM of 3" to either side of the MAF itself. 6" is best.
They need at least one flow corrector (screen) and the inside diameter of the tube needs to be 3.375 inches.

It's too bad the AEM isn't winter friendly...that leaves only the intakes that don't extend too far down, so the Injen, K&N, Racing Beat, SR motorsports, and now this one...
However I am unsure if they would actually provide any power increases over the stock airbox and with just a catless midpipe...adding on a catback would make the car too loud =(
but 12 whp...that's pretty good...but I'm guessing that is compared to a completely stock rx8? not just the aem vs stock airbox both tuned type deal with same exhaust. So real world gains would be less than that even with a tune.

Instructions...
Warm up the car.
Turn it off.
Plug the AccessPORT in.
Load the MazdaManiac "1_0" calibration.
Start the car again.
Look at the fuel trims on the "live data" display on the AccessPORT.
If the fuel trim is net POSITIVE, use the corresponding "1_Xb"correction calibration.
If the fuel trim is net NEGATIVE, use the corresponding "1_Xa" correction calibration.
Replace "X" with the amount your fuel trim is off, give or take.
Drive around for a day or so.
Send me a GRAPH showing your WOT AFRs in 2nd and 3rd gears and your AFR at 4200 RPM with the cruise control on on a flat road with the A/C and all of your lights turned on.
Make sure that in the BODY of your e-mail you answer the 10 Deadly Questions in POST #1 of this thread.
You can make the graph with a cocktail napkin and a crayon for all I care. Just make sure its a graph and representative of the reality as observed or you will get some weird results!
Could it possibly be easier than that? Watch the video. Read the first post.

I guess I missed it but hadn't known that I should start the car and warm it up before plugging the AP in. It's probably in there somewhere and I simply missed it.
It's good to know that the A/C and head lights should be on when doing the cruise control capture of data.
I can round up a co-worker with crayons and cocktail napkins to log the data. Are the graph points a delta t? How many data points? Better yet, any recommended data logging software? I've computers coming out my ears since I'm a software developer. If there's an easy way to hook up a USB connection to a laptop with some logging software, fantastic. I read through a number of forums on it an found some names mentioned but nothing conclusive. I did find out in one of the Cobb forums that you've stated there's enough memory for loggng data in the AP but Cobb just never put it in there. That's a rather egregious omission for a $700 piece of hardware.
Once the idle trim is correct (a few % one way or another is totally no big deal - in fact, up to 12% is acceptable since the PCM can go up to 22% before it starts to struggle), drive around in various conditions less that high load and see if the LTFT stays within +/-6% or so of the idle trim.
If so, you are good to go!
It is NOT unusual for there to be +/-12% or less LTFT after several days of driving.
If so, you are good to go!
It is NOT unusual for there to be +/-12% or less LTFT after several days of driving.
It may be a drag that Cobb called the A/F "equivalence ratio" but wouldn't it make sense to stick to their terminology? When I send the email to you with the sustained AFR over 4800 RPM for 30 seconds, is that a peak AFR or the end value or points along the way? I'm going to assume that AFR and A/F and "equivalence ratio" all mean the same thing?
I'll try to follow this one to a tee:
The calibration set that you receive is NOT a "tuning" set. Changing calibrations up or down the series is NOT a viable way to alter the target AFR values or gain power/drivability. The series is ONLY intended to discover the correct MAF calibration for your particular vehicle and intake setup. FAILURE TO FOLLOW THE DIRECTIONS PROVIDED HERE EXACTLY WILL YIELD A POOR TUNE AND INVALIDATE ANY FURTHER TUNING ATTEMPTS!
I'll readily confess my ignoramce about car tuning and its requirements. That's part of why I did this as I thought it would be a good way to learn.

Hey Jeff,
I've sent 2 emails concerning that p0410 cell, with applicable AP maps, the name on the email is mikelogan427@yahoo.com. You told me I probably didn't have the new update. The Cell name is AIR System problem. I'm also getting an RKE p0039 - I think that is the supercharger/turbocharger one.
2004 MT rx8
hks hi power single exhaust
ap underdrive pulley
greddy turbo kit
type RS BOV
Forge BC
mlogan/hydro/mike logan.
You can contact me at my new email address: mikelogan427@live.com.
Thanks
