Hi GTSBoy, I have located pin 7 which is tacho out from ecu but the issues is I don’t know how I can test the signal. I’ve been searching the forums on how I can test the signal output from the ecu but can’t find anything. Only thing I found was a post about someone using an oscilloscope (which I don’t have) to check the signal output. Do you know how I can test the signal output with just a multimeter ? Cheers.

Having issues getting my tacho to work. Brought the car with a a broken tacho which I thought was an easy fix as it’s a common issue with the r33 gtst. I just purchased a cluster from a private seller and swapped it out, everything but the tacho is working on the new cluster as well. I have been troubleshooting all night trying to figure out what is wrong. On both clusters, the tacho does not move at all. What I’ve done so far: - swapped cluster - checked both clusters for obvious faults like burn marks in pcb, poor solder joints etc - confirmed the tacho is receiving 12v power when plugged in - confirmed continuity between pin 7 on harness and TAM behind cluster My 2 suspicions are: - I have really bad luck and the cluster I brought - No tacho signal output from ecu I really don’t want to go and buy another cluster, so does anyone know how I can confirm the signal coming out of the ecu pin 7? Cheers.

R33 instrument cluster - tacho swap auto to manual cluster

Awesome thanks admS15. -
Hi, Just brought a r33 gtst and the tachometer isn’t working. I’m wondering if I can swap an auto tachometer into a manual cluster ? Wanted to do the same for the speedometer as it can be temperamental but I have read that auto speedos can read higher than the speed you are travelling. Any help would be greatly appreciated. Thanks, Ismail
