I am having similiar issues at Brad is having

Last year when i went racing i was hitting my Rev Limiter at the top of 2nd and 3rd Gear and was running 11.6 in the 1/8 mile, i then was manually shifting my car and dropped it to 10.6

I bought HP Tuners to try and fix my issues


This weekend i went racing and my best run all weekend even with trying my stock tune was 11.7X in the 1/8th mile there was a delay at the top of 2nd and then it shifted hard and good into 3rd and i picked up speed


I have a 2000 Z Auto with HO Mani, Pacesetter Header, 2.25 exhaust from Header, MD9 Crank Pulley, TTR Upper

Im thinking the HO Mani is robbing me of low end power for sure but i would really like some advice and insight of what to do with this tune

I am going to order a Wideband real soon and get into the Auto Tune that Shifted wrote

I am also swapping in my HO Cams, Ported Head and thinking of going back to Stock Mani if i can find one

Would anyone be interested in looking at my Tune i was using and trying to help?

So did you get the shifting issue fixed? If not send me the file you had with adjustments (I still have the one you had sent me before). As for fuel and timing tuning until you have a wideband nothing we can really help you with. You could try adding a couple degree's timing and logging for KR. Are you getting any KR currently?



FU Tuning

Yes while under WOT i think im getting 0

Other times i think im getting 4-5 KR

I will pst a log of me zipping around before we went racing

I will email you that John
