Simon Posted July 3, 2019 Report Share Posted July 3, 2019 Check that you have Jumper J1 fitted on the board this puts a pullup on for the tacho. Note the ECU is not driving the tacho this is from the igniter module. So the Sweep function will have no impact. Quote Link to comment Share on other sites More sharing options...
bocia79 Posted July 3, 2019 Author Report Share Posted July 3, 2019 thanks for your reply. In my car there are no igniter module, but ecu drive directly 2 coils. In any case there is a tacho signal in oem ecu, but i think is a feedback signal from coils to ecu. Is right? Jumper add pullup in my wire to tacho?
