In need of insight from the Gurus
A little about my project. 2pc rear main, 385 i built about 8 years ago, 10.5:1, 6" rods, TFS 23* heads, jesel belt drive, roller cam with 4/7 swap. It spent most of it's life in front of a T-56 with 4.10 gears,(dynoed 340hp/370Tq, and rich). I am using two 350 TBIs, 4 ~60# injectors, a '7427, $0E, with Rbob's 4-injector upgrade, APU1, and TPV5, and LM-1 fed into the datastream.
After getting this thing running pretty well with the info that is already on this board, I have an issue.
1. To get more TPS AE which direction do I change the #s in the -delta TPS AE, multiplier, and coefficient tables. I kind of figured I would need to work them over a lot.
so you're not sitting watching the car turned off here is a datalog breakdown:
12:09 good WOT run
22:08 WOT
24:43 WOT
25:25 Lean bog
38:45 slow acceleration good AFR
39:35 little faster but lean
40:15 lean again
40:45 40% TPS but lean
41:25 similar
42:40 60%TPS looks good
44:06 80% TPS Lean
Any other tips you can think of would be great. Thanks
