Doing some thinking and more reading, but is it possibly to integrate a standalone EMS with the stock ECU to retain CANbus functionality? Can you cut the outputs controlling engine functions from the stock ECU, so it can't interfere with the standalone, but still allow the ECU to read inputs and keep it happy from throwing a CEL? As long as the tune for the EMS is keeping the engine running within the stock ECU's thresholds for throwing CELs, I think it could work.

My bad luck build
