Everyone's basing these findings off the live data screens on the AP, correct? I'm going to do data logging this weekend with my scanalyser. I am not seeing the lean conditions you guys are seeing on the AP, and I don't have the answer why. I'm seeing AFR's around 13 to 12.5 at WOT.

Thanks for the clarification. I thought I was doing it right per the instructions. I'll get to play with it more this weekend. Hopefully I'll make it to exploring the "Stage 2" maps.

I have the RB Ram duct with Revi.
Mine was perfect fuel trim at idle.
According to instructions I did not need to change a thing BUT...
When you looked at A/F under load and Full load same problem as worm.
So I'm at 1b and it works. Will go to 2b next but need to watch the bottom end to make sure it's not lean.
2b should put me near 12.5 then I will need some fine tweaking.
After that I will go to the full Mod version for the track to check out the stats.

*** From the email ***
MM 2004 MT NA v1_0.ptm - start file, no trim
MM 2004 MT NA v1_1a.ptm - adds 2%
. . .
MM 2004 MT NA v1_1b.ptm - subtracts 2%

Yes - uninstall the AP first (otherwise Mazda can't re-flash you!) and then when you re-install, it will save the flash that Mazda put in there.
Clarification -
If your fuel trims are POSITIVE, you go with the "a" series to lower them.
If your trims are NEGATIVE, you use the "b" series to raise them.

Trimmed it back out and about to move to 3.0...

I'm lurking in this thread waiting for Christian to surface. Is Cobb taking a bribe from Evil Twinkie to hold back on 4 ports? Us poor old 4 ports need love to. I've bothered Jeff way to much and have come to realize he can only work with what Cobb gives him. Come on, summer is almost here and this car deserves a better summer than last.

Yeah, it appears that the CEL masking is only partially working. Some mask and others do not.
I put in a "ticket" for that.
Probably not a big deal, but Cobb understands that this is one of the primary reasons why people want the AP in the first place. So, it will hopefully get resolved immediately.
I also noticed that I didn't turn off everything in all of the calibrations.
There are a few that I intentionally left in place because they are useful (things like ESS failure, TB problems or CAN errors), but there are a couple of emissions things I missed.
If you get codes, just post them up and I'll see what is going on.

sorry if asked before...
I am still waiting on my AP however I had a question for MM!
From reading past post I perceive that it is recommended to have the BOV recirculated to work with a turbo set up!
I also noticed that MM turbo 8 is vented to atmosphere with the AP! How did you do it?
Is there anyway I could keep my BOV to atmosphere as well?
Or that is a NO NO....

I presently have the TurboXS RFL BOV installed! (which I love, It is loud.. I guess I am also an attention ***** 
)
do you guys suppose I will have any major troubles? Have you had any experience with this kind of BOV?
I noticed what Mysql has done! however I love my BOV sound

OK, I just logged my car with the CanScan with the Cobb Stage 1 map and my car is indeed running as lean as hell. So my theory on it just being the AP display is completely wrong. I'm flashing back to stock for the time being.

Jeff - I'm going to e-mail you a log I have from last week on my car with the stock calibration. It has throttle, rpms, airflow, IAT, and afr on it along with some graphs and analysis. Can you please take a look at the data and see if it compares to how you did the fuel maps (as your stage 1 map looked as lean or leaner in real time as Cobb's on my car)... maybe this can help us out who are running lean?
...everyone say a prayer for my cat...

I will be posting a video shortly that shows how the recirculate works in action, how the ap numbers compare to a wideband and how the ap runs going into boost. Unfortunately my other car has a flat. So I'm in a waiting room sitting around for them to patch the tire.
so likely up within the hour...

As far as the dongle communications are concerned. We have used that dongle design with great success for years now and I do not believe a connectivity issue exists, although we are going to continue testing. I believe that the reported failures are due to keying off the car while asking the AccessPORT to monitor data. If the ECU loses power during any communication process, the dongle must be unplugged and plugged back in since the device communicating to it (the ECU) has effectively been powered down. Does this make sense? You cannot ask the AP to talk to a device that is getting the power cycled to it. Please take into account that the power is cycled to the ECU when you start the engine. Like with most vehicles, all power is cut off elsewhere to allow more current to initially flow to the starter motor. Please take that into account when you are working with the AccessPORT. Try to not have the device in Live Data mode as you cycle the power, otherwise the communication link can be compromised.
Take care,
Christian.
