I'm trying to get my Actual A/F ratio to match my commanded (11.8) while in boost, by logging the A/F ratio error % and then adjusting the VE table based on the % of error. In my second log this appears to have worked great up to 140 kPa, but after that it didn't seem to do anything at all. Especially in some areas, such as around 160-165kPa, I took out 8-10% from the VE table (used copy, paste special->multiply by %), and the AFR error% still remained the same at around -8. Why didn't it change at all? I would of thought by taking that much out I should of seen at least some improvement. Both runs were done in 3rd gear, 1:1 ratio (4l60e). In the second log (AFRErrorTuning2.hpl), my 3rd gear pull was the very first run you see where the inj duty cycle climbs way up over 100% (at the 10400 - 10500 mark).
Some information about the truck:
'01 S-10 with 4.3L V6. Mach Performance kit: Procharger P-1sc at 10psi with 3-core intercooler.
Procharger FMU.
Forged pistons (8.7:1 cr), h-beam rods, bored .030 over, bowls blended on heads, 3-angle cut valves.
Running 2-Bar OS with GM 2bar map sensor.
Attached are my two logs, and two corresponding files that go with those logs, and my config file for VCM scanner.
Step 3-2BarVETuningBoostTuning3.hpt was the file used while logging AFRErrorTuning1.hpl
and
Step 3-2BarVETuningBoostTuning4.hpt was the file used after adjusting VE table based on A/Ferror%, and was programmed into the truck during the log of AFRErrorTuning2.hpl.
Any help that can be given would be most appreciated. I'm at a point where I'm stumped and not really sure where to go next with this tuning.
