This is a strip only car running a 98 ECM. I am running it speed density using a 4150 throttle body, no MAF, No O2 sensors.

What is the quickest easiest way to make WOT AFR adjustments at the track using EFI live.

I first tuned the car many years ago using LS1Edit. I just got EFI live and still learning.

Thanks for any help,
Rick

VE table - actually, backup VE table because you are using a 98 in SD...

Actually PE table is probably easier.
VE should be setup nicely and then AFR changed in the PE.

Eitherway set your PE triggers right and adjust PE vs RPM to suit..

Go back later and clean up your VE with a wideband so its accurate.

I wouldnt mess with the VE table.

I should have been more clear...

PE is your commanded table - set that to your desired AFR - then, using the wideband, make changes to the backup VE until the wideband reading matches the commanded... Do you know how to do autoVE tuning with EFILive?

If, after you have your VE dialed in, you want to make small changes in commanded AFR to see how it affects performance (i.e. going from 12.8 to 12.6), then you make changes to the PE...

Actually no, I just recently got efiLive and have not had any time to really learn it.
Plus, this is a strip only car and only 1/8 mile at a time. No sure how much data I can get that way...
But would love to learn!!

PE Vs. RPM = B3618, right?

What tables can I ZERO out/turn off..etc.. I need to make it as consistent as possible and do away with as much variables as possible. Such as, hot fueling mode, etc...

Since this a bracket car, may have to be hot lapped..etc, I do not want to worry about the unexpected tune changes based on coolant temps and such.

Thanks,
Rick
