Run the ECM on its own kill switch? But i guess that doesnt solve the problemWhat does everyone do with the battery disconnect switch and the ECM power? Right now my switch disconnects everything but that also kills power to my ECM which resets the memory. My plan was to disconnect the battery whenever I'm not driving it but it would be nice if the ECM could keep it's memory.
I wasn't aware that ecm needed power constantly or it resets. All I thought it needed power always for was for the obd2 monitors to not start over and if running a tuned ls swap or such you can kill power everytime and it doesn't affect how the motor runs. Someone correct me if I'm wrong but I would kill all power to a holley ecu and everything when power switch is turned off. Just like my old Tacoma and rangers I've done it to as well.

That's what I was thinking about as well for my vehicles since they idle high after the battery's been out for long periods of time.I mean I could be wrong but i thought it wiped all the "learned" parameters like air/fuel ratios. It definitely kills the OBD stuff.
In the stock configuration, is the ECM B+ always on? I wasn't sure if that was it or if that drew too much current
