The Factory value for min injector PW of ~0.8ms is actually VERY close for these injectors. When I originally made the measurements for FIC, there was no need to update some values (min PWM and short pulse limit), so they were not included in the injector data.
Thank you, that worked! My injector ms time didn't go down much, like .2, but that's all it needed to run normal.
I have the MPIV1 so I must use the serial connection. The funny thing is ,I also have an EFI V-2 and can read and log both AFR and Lambda. Anyone have any ideas. I really would like to use HP to correct the MAF andd the VVE as the process looks much simpler. Thanks in advance. Lanny

New here and just getting started with HP Tuners. I have just finished a new GM crate LS3 in a 83 Jimmy. Using PSI wiring harness ECM and TCM. 4L75E. It is running rich all the time with long term fuel trims @-19 to -25 consistently. O2 sensors are switching normal but low. To start I was getting a Random Missfire code p0300 and ran -25 LTFT.
Please understand. The cam angles have to be zeroed out in the regime where DoD used to operate. That extreme cam advance is for 4 cyl mode.
It's mainly just the truck torque converters. Both the 6L80e and 6L90e have the problem in the V8 trucks. I believe the V6 trucks used a different torque converter with a much lower failure rate but it wouldn't work behind the V8 engine.
