95 LT1 using lT1 Edit to adjust the tune.


normal acceleration AFR is 11.7 and once I go WOT the AFR drops to mid 8's to low 9's N/A . I am just looking for a suggestion on where the tune should be adjusted and approximately how much.

Thanks

Looks like your car is stock, why not put the stock tune back into it and see if that fixes it? If it doesn't, something is really wrong with o2 sensors, injectors, vacuum leaks, or exhaust leaks assuming it is firing on all 8.

But to answer your question, the two fuel enrichment tables for temp and rpm are usually used to adjust the WOT fueling (assuming a bunch of other stuff isn't all screwed up) and no one's going to be able to tell you how to adjust that out, especially if the engine isn't healthy.

Sounds like your AFR gauge is reading 3 low. s/b up around 14.7 driving and drop to about 12 at WOT.
