[QUOTE="03cobra#2, post: 16618580, member: 52057"] Couple quick things. Monitor your STFT's. If they stay fixed you are in open loop. After the car warms up and runs a bit you should go to closed loop and the STFT's should bounce around a bit. That's a easy to tell of you are in open vs closed loop. For the Spark source codes, source 9 is what you want at idle, that will refrence your idle spark settings. Spark source 1 is going to reference the borderline / MBT table. I would make sure your car is up to full operating temp before you start logging and trying to dissect logs. Once you figure the idle ironed out at warm operating temp, then turn your attention to your cold starts / idle if you are still having a problem. [/QUOTE]
