Couple of errors and no tach
My Autometer Sport Comp tach is not working. It's reading 0
I'm using an 05 truck ECM and I'm getting the following codes
PCM] P0650 - Malfunction Indicator Lamp (MIL) Control Circuit
[PCM] P0654 - Engine RPM Output Circuit Malfunction (Pending)

If my stock tach is an 8 cylinder setup can I half the resistence (340ohm) and get the correct output on my tach or am I hoping too much that something like that would work?
