[QUOTE="SecondhandSnake, post: 16620812, member: 116684"] What are you guys using to tune it? Out of those logs, exactly where are you seeing the problem? And it's really tough to decipher when there's no AFR data. What are you using to log it? You can usually add in an analog channel pretty easily. Keep in mind when things start to go haywire, RPM changing rapidly can change load, which can move spark all over the place. It can get real chicken and the egg. I don't see anything too crazy in the logs, but I don't know what I'm looking for, and don't have a complete dataset. Double check and see if there's anything that correlates to where you're seeing the issue. First up would be MAF counts, then spark tables, and then injector data. All it takes is fat fingering one entry and things can go to trash. For instance I had one issue that would pop up 30sec after cold start, without fail. I saw that it always occurred at a specific voltage, and tracked it down to an incorrect entry in an injector voltage offset table. I'm not too far south of you guys. Might be able to help where I can (though I'm sure as hell no decipha.) [/QUOTE]
