Dougy Posted January 10, 2021 Report Share Posted January 10, 2021 Hi Does anyone know if it is possible to get the tacho working on a g4x with all aux outputs already in use? aux 1 and 2 are used for the ISC, aux 3 for the fuel pump and aux 4 is for the VVT solenoid. Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 10, 2021 Report Share Posted January 10, 2021 If you have an Atom with only 4 aux outs, then the easiest option would be to wire the coils in pairs and switch to wasted spark. That will give you two extra aux outputs. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted January 10, 2021 Report Share Posted January 10, 2021 Alternatively you could change the ISC valve from the factory unit to one that only needs a single Aux Quote Link to comment Share on other sites More sharing options...
