Tony1436215443 Posted October 14, 2012 Report Share Posted October 14, 2012 HI Everyone hoping someone can advise me here, im looking at aftermarket ecus for the R34 GTT tiptronic model. does anyone know if i can use a R34 GTT G4 plugin as a piggy back and run it with the factory ECU, so the factory still controls the Auto side of things but the G4 everything else. i was thinking if i took all the OUTPUTS from the factory and hooked them to the G4 and split all the INPUTS to both ECU's this might work, any help would be appreciated. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
