  • rev counter not working since ecu swap

    Since fitting a maxxecu the rev counter has stopped working. The settings in the ecu have been changed but it hasn't made any difference. It should just work p&p as far as i know.
    Any ideas??

    cheers

        Does your tacho settings look like this?
        And are you using GPO 8 as output?

            checked it, an tach adjustment was 0, so i changed it to the same as the pic you sent, but hasnt made any difference.

              Might not be the ECU sometimes mine stops working a thump on top of the dash gets it going till I sort out the connections.

                  Strange, that should work.
                  Maybe someone good with the electrics can adivse you on how to troubleshoot.
