Not sure about the aftermarket stuff
Heck yeah, that gives me hope anyways! Thank you for the advice.

I have seen adjustments for this in INPA, but am unsure if they are something that stay set after you exit or not. I raised my idle speed slightly the other day and it didn't store the new setting after I turned the car off

I have a copy of ISTA/D and ISTA/P using an ICOM emulator. ISTA/D works great. ISTA/P locks up the iDrive screen every time I try to use it. I have to pull the battery cable to get it to reset, so I'm not going to give that one another shot.

I need to do some reading as to whether I can do this adjustment in ISTA/D or not. Do you happen to know, or are you guys using different software now?
