Ignition coils?

   I want to run LS coils on my 3800, this seems to be more difficult than I had thought. On Pennock's Fiero Forum I had asked the question if it was possible or if it had been done. The responses I received ranged from helpful to chastising. You think I was asking them to help me drown puppies. One of the posts on Pennock's forum gave me this link PCM hacking forums. Very neat module, last post in the thread was on 9/4/2013, so it's kinda dead. This module converts the 12v signal that drives the stock coils to a +5v to drive the LS coils, I don't know if it drives them in pairs or individually.
   So it seems that I'm on my own to research this aspect of the project.This is a major fork in the road due to the fact that I have a complete wiring harness for a 2001 Buick Park Avenue Ultra, but no ECM, I could get an OE ECM and be on my way. A little web search for the OE ECM for my engine results in ECM prices from $110 with a $85 core for a cardone (junk) part to $669 with a $120 core for an ACDelco. Both are remanufactured. I could go to a junkyard, but who knows what quality I'll get. But I want to run the LS coils and not the coil pack. So I have to find a system that will run the coil setup I want. I know the LS coils need +5v to trigger, so the search for a workable setup starts.....
   First stop- 2001 Oldsmobile Aurora 3.5. I printed out the ECM connector pin out pages for this ECM and the 3.8 ECM, they are almost identical. I need to figure out what signal the 3.5 ECM would send to the coils, +12v, +5v or ground. I think it's +5v due to the fact that the circuit is described the same as the LS circuit, but that bit of info that would make me sure is missing, weird how wiring diagram information varies from car to car and year to year, you think GM would be more consistent.
   Next I checked out the Trailblazer with the 4.2 inline 6, it uses totally different ECM connectors, but it uses individual coils, but unfortunately Alldata says that it triggers the coils with a ground signal not +5v. Maybe I could make a small converter module? And I don't know if that ECM is custom programmable.
   Next up 2001 Saturn LW300 with the 3.0 v6 (junk engine). Again this ECM uses grounds to trigger the coils, but the ECM is super small. And again is it programmable?
   Number 4 possibility is the 2005 Buick Rendezvous with the 3.6 v6. The schematics for the coils looks very similar to the LS diagrams, but again with the programming.
   Lastly I think I could use a LS ECM, like a 2004 GTO with the 5.7 LS, the LS ECMs are supposed to be the most easily programmable. I don't know if it can be programmed for a v6 though.
 
   If I could get some of my questions answered on the above problems I might be able to formulate a plan. But I'm not sure which sites to ask, Pennock's Forum seems to be more based in stock swaps and rebuilding. PCM hacking forum is kinds over my head, thoses guys are so deep into the electronics I need a translator.
   So all this leads me back to the MS3xtra. From Diyautotune it will cost around $670. A little steep for my taste, but open programming, and it will run pretty much any engine combination I put in the Fiero.

Super new direction!

Yes I changed the title again, but for a "super" good reason. I have a 3800 s/c engine, technically it's a series 2 L67. It's out of a 2001 Buick Park Avenue Ultra. A local dealer screwed up a oil change and caused a rod knock, so my shop (me actually) installed a used motor. I got the used motor for $125 core charge. My plans are to do this on as tight of a budget as possible, I'm trying to build a daily driver not a show car.

Super charger was removed and put up on a shelf to keep it safe while I worked on other stuff.

Water cooled drive belt tensioner, kidding, unused heater passages and alternator mount visable.

I removed the plastic coolant elbows, tapped both holes in lower intake manifold and timing cover. Hole in lower intake will have fitting installed for heater flow, hole in timing cover is plugged.
