I was referred to this forum from another site. I've been reading alot about tuning but still not finding the information I need. I just got idle and 1st-3rd gear datalogs. its showing a little knock retard in 3rd gear and AFR is far from tuned.

I'm not really sure where to begin so if someone can give me a good link or take a look at these datalogs I would really appreciate it.

car is a 94 cavalier 3400/3.1 hybrid turbo at 8psi

I'm running a bit rich (9.xx range) in the upper rpms

In my "FUEL VE % vs RPM" table the values are lower in the upper rpms, but thats where im showing rich AFR. I read that lower values are supposed to lean it out? for instance at 5200rpm its at 44.14, 5600 40.63, 6000 36.72. so do I need to set those even lower?

modifying the "FUEL PE Air / Fuel Ratio" table would not actually change fuel then? is it just where you put the AFR you want, and compare that to the actual AFR in the datalog?
