Hey guys,
I went through trying to set my fuel trims and such through link and I was going about 65 and keeping steady rpms, and my afr was bouncing like crazy along with my stft and ltft lo. Also, my idle is a bit funky. how should I go about setting the idle? (not just rpms, but fuel trims and such) first off, I don't have the option to log icsposition. (still cant figure out why) my idle was creeping pretty bad, from 850 when I got her warmed up to 1100 as you can see in the log. Why would my fuel trims be going crazy like this and how do I fix them?

Also when I first start the car she runs unbelievably lean and stalls or just sits at like 500 rpms just shuddering and such. I have a safc2 and im trying to get that set to 0 so my ecu has full control and I can take it out. I have to turn the fuel up to 50% gain on the injectors just to make her idle smooth and still she sits above 20:1 in link. :banghead:

Are you on a MAF? I'm sure you know this but a boost leak will mess your idle all up on a MAF and it would be a pain to try to tune it out.
 
1. You should remove the SAFC-II if you are trying to run ECMLink.

2. Does that car have a 255lph walbro with no AFPR? If so, that could be the cause of your idle issues as well as your random fuel adjustments.

3. Are you seeing an knock on Link?
