RaceCapturePro RPM
Getting the right RPM signal can be challenging depending on the engine and ECU. Here's a guide for connecting RPM on various vehicles and engines. We'll be adding vehicles as we have more information.
I don't see my car listed
If you're handy with wiring, look up your car's diagrams and look for a tach signal - either a signal feeding the instrument cluster, or a wire from the ECU feeding the igniter. Then email us your findings or questions and we'll get your car added to the list here!
Also, if you've successfully tested one of the unverified configurations below, drop us an email so we can make a note.
