I currently have a b6t running ms1, Im having problems with a missfire, the current set up is using the b6t dizzy with the advance weights tack welded in place and the vacuum advance locked out, im also running a GM 7 pin hei ignition module. Im thinking there might be a issue with the module or possibly the pick up in the dizzy. I was thinking of swapping in a BP dizzy to eliminate some possible issues due to there not mechanically controlled. My question is can i use a N/A dizzy or does it have to be a BPT dizzy? what do i use for a ignition module? does anyone have a wiring diagram so i can see how to hook this up? The wiring and megasquirt where not done by me so im learning as i go.
