Coil per cylinder 4.3?

[mecanicman]

I have the original gm training literature from 99 on the shortstar, its a 24x crank reluctor and 1x cam reluctor. It uses a dual pickup crank sensor so if one side fails the engine keeps running. Cool project!

!! !

are there any detail specs on the trigger? is it the same as the LS1 trigger?if it is, that makes my converions plans much easier! do you have any detail pictures of the crank trigger, and the pickup angle?

Thanks-

Camshaft Position (CMP) Sensor

The camshaft position (CMP) sensor is also a magneto resistive sensor, with the same type of circuits as the crankshaft position (CKP) sensor. The CMP sensor signal is a digital ON/OFF pulse, output once per revolution of the camshaft. The CMP sensor information is used by the PCM to determine the position of the valve train relative to the crankshaft position.
Camshaft Reluctor Wheel

The camshaft reluctor wheel is part of the camshaft sprocket. The reluctor wheel profile is a smooth track, half of which is of a lower profile than the other half. This allows the CMP sensor to supply a signal as soon as the key is turned ON, since the CMP sensor reads the track profile, instead of a notch.
Crankshaft Position (CKP) Sensor

The crankshaft position (CKP) sensor is a three wire sensor based on the magneto resistive principle. A magneto resistive sensor uses two magnetic pickups between a permanent magnet. As an element such as a reluctor wheel passes the magnets the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse. This system uses two sensors within the same housing for the V6 engine, and two separate sensors for the V8 engine. The PCM supplies each sensor a 12-volt reference, low reference, and a signal circuit. The signal circuit returns a digital ON/OFF pulse 24 times per crankshaft revolution.
Crankshaft Reluctor Wheel

The crankshaft reluctor wheel is part of the crankshaft. The notches on the reluctor wheel provide a unique pattern for each pair of cylinders that are at top dead center (TDC) at the same time. This is known as pulse width encoding. This pulse width encoded pattern allows the PCM to quickly recognize which pair of cylinders are at TDC.

is your manual a digital copy?

[mecanicman]

No, I copied and pasted that out of si2000. No more info or pics in the book on the topic. Pm me your email, ill forward you a couple technical drawings, dont get your hopes up.

I never figured out if it was a joke or not, but I received a very legal type email from another forum I post on. I was posting a lot of gm stuff I have access to, so I don't do it any more.
