Hello all.
I managed to get my generator wired up today. Then I re-installed the PTO.
Everything works perfectly!
If anyone is trying to upgrade their M1031 to an APECS4500 controller, I now can program the controller from a known good calibration.
When I turned the system on, it took a moment for the controller to seek the correct RPM, after that, eveything works great.
I make no warranty of the file, use at your own risk. I am using it on my truck.
I will charge $0.00 to program your controller.
If you wish to do so, send me a message to arrange it.
If you send me your controller with prepaid return shipping we can get it done.
I will send it back with a wiring diagram from the creator of this upgrade. I intend to change the wiring on mine to re-incorporate the safety switches and add a low oil pressure cutoff.
