Vaughan Posted March 2, 2021 Report Share Posted March 2, 2021 So engine is running but tacho is showing 0? is Ignition Drive 5 set to Tacho? ameer 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 2, 2021 Report Share Posted March 2, 2021 Also, tacho is on a different aux depending on the bottom board revision number, you can find it where I have marked the pic below. I dont remember exactly when the change was made, but if it is somewhere around V1.5 or lower then tacho is on Aux 4, newer versions tacho is on Ign 5.

Adamw Posted March 3, 2021 Report Share Posted March 3, 2021 Then tell us the version number of your ecu as I have shown above and attach a copy of your map and we will take a look. ameer 1 Quote Link to comment Share on other sites More sharing options...

Adamw Posted March 17, 2021 Report Share Posted March 17, 2021 V1.3 bottom board should be fine. Need to see your map. Ensure aux 4 is set to tacho and ensure no other aux, fuel or ign outputs are set to tacho. ameer 1 Quote Link to comment Share on other sites More sharing options...
