Adamw Posted November 28, 2021 Report Share Posted November 28, 2021 The Evo 9 ecu drives the tacho directly from the crank sensor, the ecu has no influence. This was done to free up aux outputs for other functions since this car is quite hungry on outputs. To make the sweep work, you could move the tacho wire (pin 45) to Aux 10 on the expansion connector. Quote Link to comment Share on other sites More sharing options...
