kelvin1982 Posted April 12, 2019 Report Share Posted April 12, 2019 Hi, i have one of suzuki jimny jdm and swap to suzuki M16A VVT engine with Linkecu G4 plus civic 92-95 connector. I have set my tacho out with Aux 6. But why my original tacho meter still not working. It's the setting problem or wrong signal. Please tell me how to solve it. Thanks.....

Adamw Posted April 12, 2019 Report Share Posted April 12, 2019 Aux 5 & Aux 6 on the H92+ ecu where designed to highside drive the VTEC and Intake solenoid so they have a special highside drive circuit added which basicaly inverts the signal. You could add a pull down resistor to make it drive a normal tacho but Im not sure if that's all you will need. Was the Suzuki Jimny tacho originally connected to the ecu or to the ignition coil?

kelvin1982 Posted April 12, 2019 Author Report Share Posted April 12, 2019 Thanks for you reply, so what you suggest for tacho output, witch Aux is better. The original tacho is connected to ECU. Quote Link to comment Share on other sites More sharing options...
Adamw Posted April 12, 2019 Report Share Posted April 12, 2019 Aux 4 (pin A20), Aux 3 (A15) or Aux 8 (exp) would be easier if you have either of those free Quote Link to comment Share on other sites More sharing options...
