The 2021 GMC 2500 L8T 6l90 came with an E93 PCM. Not using because the I/0 is not correct for what I want. This particular E93 I/O configuration does not have an output for electric fans and the associated FPCM (three phase AC pump) does not have aftermarket support for a larger pump. It appears that all the vehicles with the E93 have this fuel pump configuration.
I did a lot of research (This forum, HP tuners Forum, RockAuto, gm direct parts, ACdelco TDS, Autotrader) and came up with the E92 PCM from a 2019 5.3 Yukon, bought at salvage yard. The 5.3 Yukon has a T43 (6L80, electric fan output and FPCM aftermarket support pump increased capacity). A 2021 Camaro PCM came to mind but no 6-speed configuration for that year.
Yes, I want to keep the factory return less PWM fuel pump feature.
Engine and trans are on a stand, I mocked up the High Speed GMLAN between the 2019 E92 and the 2021 6L90 T43 and read both. I can read it, do not know if they will function together.
