Controlling a GM 4L80E with a FORD PCM ?
Posted: 2021 May 07, 18:33
I'm tossing around the idea of a 6.0 LS swap into my 2003 Expedition. I've only just started wondering about this and the first two configurations that cross my mind are.
1. Make the LS run from my Expeditions PowerPC HAP3/RKAOA/HPC-313 find an adapter and keep my 4R70W (This way no driveline work needed)
2.Use my Expeditions PowerPC HAP3/RKAOA/HPC-313 and try to have it run the LS and a 4L80E transmission. (may need an EPC solenoid mod?)
I checked and both 4R70W and 4L80E have the same number of solenoids and use the same truth table to operate the gears. My Expedition is the Eddie Bauer with advancetrack/ABS and a bunch of stuff that would probably be very difficult to run without the Expedition's stock PCM.
Could the FORD calibration be tuned to run a GM 4L80E? Does anyone know how the get a 4R70W mated to a GM LS engine? I can't seem to find an adapter. I can weld, fabricate, and understand wiring and schematics also I realize this is kind of a weird idea. Please give me your thoughts minus any of the blasphemy type criticism.
