Default Ls2 SD tune help - VE overshooting

Hey guys , im not new to LSx motors but new to tuning.

Im trying to attempt a speed density tune on my bolt on /stall cammed ls2 06 TBSS


My corrections keep overshooting, not sure when Im forgetting.

For the WOT open loop wide band portions I have the arf err cell min count set at 4.
During STFT tuning I had it at 25 but

Im using a AEM wideband, looking at my histograms im getting accurate a/f commands and accurate readings to the gauge.


My problem is every time I do copy -multi % special half the numbers overshoot.

What am I missing.

Thanks

I just do the changes cell by cell. I find that approx 70% or the error works well for the larger errors. 50% of the error for the lower errors.

You can also just chose the paste special mult by half over and over.
