Opps....OK revise to say....
The output from the Crank sensor sensor is also used, in conjunction with the start of injection sensor, to determine and control ignition timing.
The ECM uses the input signals from the start of injection sensor, together with signals from the crankshaft position sensor, to detect the actual start of injection angle. The detected actual value is adjusted by the ECM to a nominal value via the injection timing solenoid.
As it does in RAVE....
(but what is said is wrongerer than mine!!)![]()
Have never tried it so can't say, but it would seem to be possible. The engine does need a speed signal to even tick over but it would get that from number four injector. So what he says does seem plausible.
