Ls7 Ltft

[S2002S]

I'm looking for some help. I did some tuning on my LS1 and now want to work on my stock 2007 z06. The LS7 doesn't have a VE table, so what the recommended histogram for checking LTFT?

RPM vs ??

Any other pointers or links would be appreciated

Thanks,

Brad

You should log LTFT vs MAF HRTZ (low). Use the MAF to adjust.

Hi,

So basically we should copy the values from the MAF low and use the special mutiplier to adjust? Do we need to be outside PE and in openloop for that? I have found out when the Ltrims are high and positive, the throttle response seems to be better and so is drivability, does that make any sense? Also, on a different note, what do we do what the actual AFR doesnt match commanded Afr?

thnx
