Does anyone know where to get a rpm signal from when doing a dyno? I went and had my truck dyno today and my dmax was the first one he has ever done. We could not get a torque read.

You need a optic sensor .... Reading is taken off the crank pulley via sensor mentioned and a strip of reflective tape attached to the pulley....

On a DynoJet you can use the injector signal to get RPM. We use the loom of wires just uder the turbo discharge hose on the driverside to get the signal.
