I have a 2022 7.3 Godzilla new take out that I'm running a stock PCM and plan to run with a TKX transmission. I've built my own "control pack" and sent the PCM off to have PATS tuned out and the guy doing that said he also made some changes to make it a standalone PCM. I have the engine on a run stand and when I first applied power to the control pack the fuel pump relay buzzed and the ignition switch will not start the engine. I've troubleshooted the fuel pump relay and I really believe its related to something not setup in the tune correctly and not fully energizing the relay. Anyone have any thoughts on this? I looked at a 2019GT coyote tune from a MARS control pack and I don't see anything different they did in the tune from stock to make the fuel pump relay energize.
The motor will start if I jump the starter solenoid but the ignition switch doesn't do anything. I do have a clutch switch wired up and completing its circuit, is the pcm looking for a neutral safety switch input as well?
The electric fan runs all the time when the motor is running and I'm hoping this can be fixed. The original godzilla ran a fan clutch and FC-V wire ran from the pcm to the clutch. I think this is PWM and I'm hoping this can be set to trigger the fan relay at the temp I want it to come on. Any thoughts?
Lastly the only codes I'm getting are emissions and auto transmission. Should I just disable the auto transmission in the tune then turn off the MIL light for all of the auto trans codes?
I've downloaded HPtuners and am waiting for my MPVI3 to arrive this weekend so I can pull the current tune off the PCM but I'm just trying to get some ideas on what to look for on these issues. The motor starts great, and idles well, throttle pedal works and it revs well.
