I'm not 100% sure what makes something qualify as a "race file" (maybe 100 oct?) but they have the following maps available OTS

stage 0 (stock)

valet

anti theft

stage 1 (drop in filter recommended but not required)

Stage 1+ Bigsf intake (requires Cobb Cai)

Stage 1+ stock maf (requires cai with stock MAF housing. Cobbs intake has a larger diameter maf housing)

Stage 2 ( intake and full turbo back recommended but many run with just an intake and dp)

All stage maps are available in 91 or 93 octane

Race files are usually 100 octane maps or some kinda ethanol blend map.

What monitors should I be checking with my AP to determine if my car is running ok?

I like to watch knock in each cylinder as well as LTFT and STFT to make sure the AFR fuel trims are looking correct. I also watch AFR to make sure things are looking right there.

LTFT and STFT should be as close to 1.00 as possible. I was having fuel trim issues with my intake on the OTS maps, so I was seeing LTFTs as high as 1.15 at times. Protune fixed that right up.

AFR should be right around 14.7 at idle. 14.7:1 is stoichiometric and will spool the turbo the most quickly, but that AFR will get richer as you apply throttle to keep temperatures under control. For the most these numbers should look okay, but I like keeping an eye on them in relation to LTFT and STFT.

So I took mine in to the dealership today and they'll be doing an ECU update from a Nov. 2015 service campaign. Just curious if when I flash my stage 2 again after the update if it will incorporate the changes or if it will have been literally worthless having them update it. Does the update change the engine box code? Also, I didn't uninstall the Accessport before taking it in, hopefully that won't cause any problems when flashing it back to stage 2.

I saw some other mentioned it months back but is there anything still in the works for being able to use launch control? or 2-step?
