Thanks for that info... Its prob stupid to think I could just hook it up and it would work.. But were all stock LBZ fuel rates the same, could the values already be the same? Did not ask if this was from a stock tune or if it had a tune on it, but? If it won't hurt anything, its worth a try. And, if you can copy/paste the values from the ECM, having the GPCM pre-installed before putting it in for programing at the shop would be ok also.. Maybe it kills the U0106 code, that would be a good sign.. I know fuel rate codes would no doubt throw it into limp mode, but it would confirm the U0106.... Any thoughts

Apologize for joining in this convo late but just have a question. Am throwing an s400 on the truck this winter and in the process of cleaning up the engine bay and such and deleting the gpcm was part of that. I got the resistor but I have one more wire from the gpcm that runs back to the main harness and has another plug that splices into it. I see no one else has mentioned this so its either unimportant or maybe Im just missing something. Just a bit lost. Thanks!
Apologize for the less then stellar pics but here they are. That yellow wire just runs back to the main harness and that red wire that came from the gpcm runs directly to that plug. Thanks again for the help
The yellow/black just runs into the heatshrink of the crank position and cam position sensor which seems odd to me. Then the pinouts for that plug are A6 and D6,D7,D8 of the bigger of the 2 main engine plugs
