Need help I feel like I'm going backwards
I am attempting my first tune. I have a 2000 S10 2.2L flex fuel to a LM4 5.3L swap. I have 243 heads. Gen 4 Flat top pistons/rods. Elgin E1839P cam
Intake Valve Lift:
0.575"
Exhaust Valve Lift:
0.575"
Advertised Intake Duration:
286 deg
Advertised Exhaust Duration:
282 deg
Intake Duration @ .050":
220 deg
Exhaust Duration @ .050":
224 deg
Lobe Separation:
112 deg
I know I must be doing something wrong, I keep getting lean or rich cells that don't seem to change or it changes from 1 cell to another. If i was seeing #'s that got progressively closer to "0" i wouldn't be so worried. In the VE vs LTFT there is large area's of rich and large areas of lean that don't seem to change. These are -7 or -9 and the next over is 8 in the fuel trims. I am either using the wrong graph to copy & paste to my main VE table or just plain not doing something correct.
I was told to use the VE vs LTFT of the scans. With a warmed engine idle to 3K with varying throttle up to 50% and 20 min drives to start.
I set the codes P0101, 102, 103 to fail on first error and set the the MAF hz to "0" I also was told that because I have MAF readings in the logs the MAF sensor was not disabled. I have a P0103 code that sets every time i write a new file. I was also told that it will register and read but not use that data in SD mode. Is it true that every time you write a new file the STFT & LTFT reset?
Not sure what other information is needed because I'm trying to expand my tuner knowledge, here my last tune file & last 2 logs. Any help is appreciated.:doh:
