Standalone System and S197 pcm

[Mrl510]

I have swapped an engine into my 14 mustang that has its own standalone Holley sniper system running it. The factory pcm is still in the car. The engine harness from the pcm is only being used for CHT and Oil pressure(that I can remember right now). The factory gauges sees/reads oil pressure, cht , and alternator voltage. My question is, what can be done to trick the factory pcm into thinking the engine is running, I wouldn’t think it matters if it happy but just to make it think it’s running. I’m trying to get my EPAS, a/c, etc. to work without having to use standalone harness and straight wiring. I figured if there is a way to just simulate whatever needs to be simulated to make the pcm think the engine is running then I may get the necessary Can Bus signals from the pcm to make the EPAS and other things work as well. Any help is appreciated. Thanks

A standalone EPAS controller is only way to retain EPAS. I have a sport mode version that is plug and play while keeping the rack in sport mode. You can find it here. https://wireeverything.com/products/ols/products/2005-14-mustanggt500-epas-controller-single-mode.
This is a complete solution and requires no input from the car. Feel free to reach out if you have any queastions!

Not sure if this will help anyone else or not but I was able to wake up the PCM enough to make the EPAS work. I took the crank sensor trigger wheel and attached it to the new motor and hooked up the crank sensor. That woke the pcm up enough for the EPAS and the tachometer to work.

Same here, put a 36-1 trigger wheel on the front of the balancer, made a bracket to hold the factory crank sensor, and bam, stock ecu thinks the engine is running, all my stuff works. Holley is running the engine
