barge Posted November 3, 2018 Report Share Posted November 3, 2018 Is there any way to supply a regulated 12V to the ECU so that it maintains comms connection during cranking without messing up all the VBatt type compensations in the ECU? Even with a stock size battery I "think" i am getting too much voltage drop during cranking to maintain comms. Unless there is a good method of logging and trigger scoping in the ECU on it's own during a crank I'd like to remain connected during cranking. I've seen some other threads about bad grounds, starter noise, etc. All the grounding is to stock points and there's not much I can do about the factory starter.
