Hey everyone. I just finished my 97 383 build and now I'm trying to tune it in. My fuel trims are way off. Bank 1 is -12 and bank 2 is 25. I had a exhaust leak before but now that its fixed I need to reset the fuel trims. How can I do this? I'm tuning with jet dst and logging with mx scan. Thanks

Reset long term trims? Pull the battery, pull the PCM, reload the tune. All three will reset ltfts or ints or what have you.

Ok so I have to do all three or just one of the three?

Split BLMs is a common problem with cammed cars. Also with aftermarket throttle bodies. Google split BLMs and read through the various fixes to see if one can help you. I have split BLMs, but they aren't that bad.

Just one of the three. The first two just leave either one unplugged for a half hour. I assume you could also pull the PCM fuse for a half hour to reset the tune.

Ok I have a very small cam cc305 and a 58mm tb. Thanks.
