MegstuBMW Posted October 25, 2019 Share Posted October 25, 2019 Hi, I have 1997 statlet 4efe turbo project, installed megasquirt ecu, full sequential spark and fuel and because of that I removed original distributor internals, car is already tuned.. My problem is original tachometer, I can not make it work. Megasquirt has rpm wire for tacho, it is configured in software, but if I join wires, tacho doesn't work. Maybe someone knows what kind of signal wants original tacho? Quote Link to post Share on other sites

MegstuBMW Posted October 25, 2019 Author Share Posted October 25, 2019 Maybe this one? Quote Link to post Share on other sites
RobSR Posted October 26, 2019 Share Posted October 26, 2019 Yes that looks correct from memory as I don’t have one in front of me at the moment. You can remove the Tacho assembly and do it on the bench You then join the ecu to the IG- pin on the cluster Quote Link to post Share on other sites

Frankieflowers Posted April 10, 2022 Share Posted April 10, 2022 I have the opposite situation. A Starlet Glanza ep91 4efte engine and ECU in a Corolla Ee110 Hatchback. The Corolla’s cluster is different as it is full electronic ignition. The RPM signal that comes from the Starlet ECU is dirty and the signal jumps. same thing trying to pick a RPM signal from fte ECU to send it to IGN pin on the Corolla’s AC computer. I hope that you can help! Quote Link to post Share on other sites
