Hi there I am currently in the process of fitting a G4 EVO 1-3 plug and play ecu. We have an expansion loom fitted and are fitting additional sensors etc and have changed ignition from wasted spark to sequential as i am running coil on plug. The issue we have is having a tacho output so the factory tacho works as it would get its feed off the stock ignitor, but we dont have any outputs/inputs left other than ecu hold power. Will it cause an issue using this output? Or is there another way?
