Busta ran a MS on his last motor too, an 8.1... He's using the EDIS coilpacks from Ford, much easier to deal with than trying to trigger the stock coil packs. EDIS and wasted spark do not work well with COP ignition, you're basically doubling the current & duty cycle on the COP coils and also doubling the power requirements form your charging system if you try to run COP in wasted spark mode...
So this is the third Megasquirt'd LS1 currently running, including turboberserker's pickup truck - which is in the final shakedown stages.
ahh got my cold start enrichments worked out this afternoon. it was 41 degrees when i fired it up. started and idled great!
I was running the Ford coil packs on the 8.1L, but i switched to GM DIS coils, like what is found on 3.8L front wheel drive engines. I have the coils mounted behind the intake on the fire wall, almost invisible without looking for them. I am going to cut the bosses off the valve covers and epoxy them in, and maybe paint them to clean it up a bit. I also ordered a LS6 intake, I may swap it out, for the looks mostly, or I thought about the Cadalliac engine cover for the 6.0L.
I am using the stock 6.0L oil pan, it hangs down a bit, but it clears everything fine.
The motor mounts are from ebay, the are copy's of what you can buy from Transdapt for $49.95.
I am running headers. I used 1990 mustang shortie headers (aftermarket, not the stock crappy ones) and cut the flanges off, heated the tubes and reamed them to the oval shape of the LS1 ports, then welded to my LS1 flanges. They cleared the frame, motor mounts, and sparkplugs just fine using 45 degree boot plug wires. i will try to get pictures of the completed swap. keep checking my website.
