    Coil per cylinder 4.3?

    ok, so we all know the 0411 PCM is capable of CPC, and some of us know the 4.3 S10 also uses the 0411. The 4.3 doesn't use CPC though, it uses some kind of distributor setup, much like that of the 5.0 and 5.7 vortec engines. has anyone converted a 4.3 to run on a 0411 with CPC?

    wiring pinouts for the S10 and typical V8 0411(trans am IIRC).

    I remember asking about this one time in the past. I was thinking about using a 411 to run a jeep 4.0 engine, and was wondering if DIS (coil per plug) was possiable. If I remember correctly, since it had never been done from the factory, it probably wasnt doable. Something about no crank trigger wheels and code to support it.
    I think if a person was smart enough and knew the code in the pcm well enough, I think it could be hacked and done. Maybe convert a V8 bin to run the 6cyl? Not sure if the V8 trigger wheel could be used or if a custom one would have to be designed and code written to use it.

    My guess is since there is such a low demand for doing this, no one has felt the need to do it. But I'm thinking if a TBI PCM can be hacked to run MPFI and use a MAF, then why couldnt the 411 be converted to run a 6cyl DIS?

    I was kinda figuring I would get a response like that. I would love to start learning the actual code and how to manipulate it. I will eventually, but I think I'm going to be a bit too wrapped up in school for the next year or two.

    TRUTH. Youre never out of upgrade long enough before you start another. Want a good EPR, there goes all your free time! LOL

    meh, I'll make it happen. might use the 0411, might go another route, like the shortstar PCM. we'll see.

    The newer 4.3 used in the GMT900 trucks used 3 coils mounted in teh position where teh distributer sits. I'm sure you could wire it up to use either CNP (Coil Near Plug) like on tyhe LS1/2/3/4/7/9/A or COP(Coil On Plug) like is used on the Ecotec 4 cyls etc.
    Here is the 2007+ LU3 4.3 with the 3 coils and long high tension wires


    Here is the 2007 and earlier 4.3 with crab style distributer used in the GMT 400 and GMT 800 trucks. Uses a single coil.


    Here is the brand new Direct Injection Ecotec 4.3 used in teh new 2014+trucks, as you cans ee it uses CNP ignition with the short high tension wires

    I should have been more specific and said using the 0411 PCM.

    With those being DIS, there is definately a crank trigger wheel made for them. The only problem I see would be getting the 411 to work with that trigger wheel.
    I'm thinking 4.3 bin from the 01-02 range (for a 411 pcm) would probably be way different than a bin for the same year V8 with DIS. So I am wondering if it would be easyer to mod a V8 bin, and alter the number of cylinders it fires and the number of pulses it see from the crank trigger, than it would be to try and make a distributor bin work with dis?
    However it goes, it would take someone way smarter than me to do it.

    Hog always has the sexy pictures!

    Somewhere we talked about this before to run COP with the 5.7L Vortec engine (96,97,98,99,00) 0411 conversion.

    In EFI Live and TunerCat there are Vehicle Platform Options and the LS engine like Camaro and newer Trucks have Low Res Crank marked No. The Vortec calibration that comes with distributor is marked Yes!

    Just not sure what the Low Res Option is for?

    I guess the answer is in the new book?

    the different ignition systems (with high and low resolution crank/cam signals)

    I just ordered the book, probably a good read even if it doesn't outline what I need to know.

    thoughts?

    I looked at which injector pins went to what cylinders between the two pinouts, and then match the coils.

    Sure looks like a good start! My concern would be the code, not sure the vehicle platform change is going to work? This is new ground. Would be nice to have a test bench for this but then again you'll have a test bench when installed in the truck...

    I need a text bench bad... once I have a shop again, it'll be on my to do list. among many other things.

    FWIW, this won't necessarily be a truck, like all the other mix match parts I own, this would be going into the Fiero.
