Welcome to MLOC forum, can you let us know what car are u driving ?
if you are mentioning about RSM, My guess that ur car should be running on digital system.
Please check
1. Speed sensor (at gearbox)
2. Speed sensor cable , harness connection
3. Ecu speed signal power status....
RSM is connected to ur ECU to bypass the speed limit, it taps the speed sensor from ori, so check the hardness of ur RSM mayb disconnected, place it at a proper place.

Been quite sometime I never post anything on the forum. Got a bad news to share with you guys. My car had total lost and I only drove it like for about 3 months. It really pain n heartache to see my car...
