DHP= Digital horsepower tuner.
does the 4.0 use a cam sensor? any GM obd2 setup capable of coil per cylinder will use a cam signal.

Yes. All 91 and newer 4.0's have sequential injection with both a cam and crank sensors. The cam sensor is a hall effect 1x signal mounted inside the distributor just like the obd2 4.3's chevys. The crank sensor is also hall effect and reads off notches in the flywheel. The number of notaches (3 sets of 4 notches) are not compatable with any gm system I know of, but mounting a new wheel and sensor on the front puley looks pretty easy.

playing the really long game here... turns out the engine I am going to be using has the same crank trigger wheel as an LS1, the cam wheel is different though, the cam wheel on my engine is a 1x missing tooth, the cam wheel on an LS1 is a 1x 180 degree reluctor.
IOW, it may be possible to run a GM LX9 with an 0411, which is way more hacked than anything GM V6.
I'll follow this up with anything else I can find.
The 2013 Chevy Silverado 1500 with 4.3 is a coil pack / coil per plug ignition system. Uses AC Delco part number D599A coil pack.
The LS1 1x cam reluctor is 175 degrees.

yep, but also starts getting into DBW and DI, and uses a 60-2 trigger instead of a 24x wheel like I need.Originally Posted by dave w

Thanks for the correction on the cam wheel, I was just guessing based on the look of it.
Blast from the past.
Why not go to DIS on the 4.3? Why coil near plug?
yeah, sure is, but the new info is still relevant to the original discussion. I was more looking to develop a way to run coil near plug on a 60V6, and thought a mix of V6 and V6 0411 configurations might work. now I see I may be able to just run a Lx9 with an 0411 without nearly as much work as I thought, although now, I'm running a MS3x, so it's kinda an irrelevant for me.
why no DIS?
I didn't like the ICM's and long plug wires for some reason when I built (rebuilt) the car, so I went with coil near plug.
