So now that the unit is up and running fairly well and the self-tune aspect has done its thing its time for the next step...timing control. I bought an HEI distributor for an 81 ( the only year that they installed FI on a true Pont motor) Pontiac FI application. It comes with no mechanical adv and no vac adv. it's a big g body HEI so I can't buy the MSD adjustable rotor for phasing so I will have to dick with things a bit to get it set up correctly. The first issue I came across last night is the magnetic trigger plug that plugs into the 5 pin module is different than the earlier years module. I didn't really want to make wire splices inside the dist but it might be the easiest way to go.
