I've installed the SVC supercharger on my 2002 P38 Range Rover and am looking for the tachometer signal.
The signal should be, for the petrol version, 4 pulses per crankshaft revolution. I need to find this for the
additional injector controller. I found one, ECU C0637 pin 17 PWM 0-5v.
Does anybody know what the pulse rate for the alternator pulse train is? Or, where I can find a tach signal?

Follow up. Yes that's the TACH, engine RPM signal line.
