I ordered 3 more IGBT for future trailing coil use. So hopefully i end up with the same 3 IGBTs. Anyways i installed the 3 you said you ended up using.

Trailing spark/coil is not supported with VEMS :(

It runs! errr should i say ran. I was testing and playing around with it when one of the coils turned into a poof of smoke. I didnt have one of my IGBT's heat sinked and it took a coil out with it. Oh well I already had 3 extras on the way last week. My fuel lines will need replacing as I mixed them up when i was purchasing them and just found out with all the leaks that they were not the "fuel approved" hoses.

When it was running it was running pretty rough. I bumped the timing up to 15* and tried leaning the fuel out but it still ran rough so theres some more troubleshooting to be done once the new fuel hose/IGBT's arrives. Looks like in the time being i'll make sure that everything is set the way it should be. Thanks again for everyone that has helped me out so far. I know it wouldnt have been running (at least this soon) without you guys.

If its running then its not called troubleshooting, its called tuning ;)
Its a good feeling when you get the engine running, no matter how rough ;D

The ones in the rescue pack are bi-directional diodes, the ones fitted internally are single direction hence the white band.  You should be fine with either type, there was some talk of the internally fitted ones needing to be single directional.

Here it is running. I'm still having problems with my injector staging so i haven't really gotten into boost yet. I had to stop filming during the drive because there were 2 sheriffs on the side of the road ahead. haha
