Ha, well that doesn't help, I guess I will be setting up time on the dyno after I get someone local who is better at MS tuning and timing tables.

I just failed emissions yesterday for High nox, 2.9 out of 2.5. I have a feeling my 15.9:1 cruise AFR's along with my not warmed up enough cat (only 5 mile drive to testing) was the issue.

So I pulled a little timing out, richened up afr's back to 14.8:1 and tomorrow I will drive it to work so we shall see if that helps.

So when looking at the logs what am I looking for to know if the timing is to advanced or not enough?
