Tech Inside-HELP!
Finally setting up the nitrous controller and looking for a tach signal or RPM signal without coming directly off the coil packs...
Are this cars a waste spark system?
Any ideas? I'll be probing and checking this thread more as I get more and more frustrated
Also best place to pull the TPS voltage?
Thanks in advance-looking to try it out tonight

The RPM signal is on Pin 47 Black (no tracer)
of C3, however, for some reason, you will get spike on this signal. The solution has been to pull RPM signal off the Camshaft Position Sensor (C3 Pin 2). Set Cylinders to "1" to get correct Engine RPM. Picture below shows the module you need to connect to

Tibi, this is only a good pick up point if you can compensate for the pulses. Camshafts spin at half the rpm of the crank. The DashDaq/Zeitronix has the capability to adjust the signal, which is why we can use it for rpm.
