I am frustrated as all get out.....any help here would be appreciated guys. I need to nail down this idle..it's driving me bonkers!
Post a copy of your tune and a log containing Desired Idle Airflow (GM.IACDES_B), RAFIG (CALC.RAFIG), IAC - LTIT (GM.IAC_LTD_DMA) and IAC - STIT (GM.IAC_STD_DMA). The log should contain a few other standard items (RPM, fuel trims, throttle position, and spark advance). Don't go over 24 channels (indicated at bottom of scanner on F8 PID page). To get the best results, make sure you capture your log when the car is completely cooled off (i.e. after it has sat out over night). Also, make sure you start recording right after you start the car all the way up to and beyond the normal operating temps - remember, oil temps rise much slower than coolant temps. Lastly, it's probably wise to leave the hood open, parking brake on, and don't touch the throttle if possible. Shouldn't take more than 15~20 minutes to fully warm up.
