msd cdi box

Does any one run an msd ignition box ? I was thinking of a slight upgrade because my tach relay bit the dust and i could take out 20 year electronics and use new state of the art with rev limiter built in.

I use the MSD6AL. Because my car has no rev limiter, I really like the "soft touch rev control". My shift light comes on at 6k and the limiter comes on at 64k.

Yes. Change to a Blaster 2 coil. I'd get the one that you can set in any position, i.e. upside down.

Did you wire it right? You have to make sure you wire it right to the distributor.

Courtesy of Steve Weiner:

Me: Since the Turbo uses a magnetic pick up type distributor, my question is which wire does the MSD violet wire connect to and which wire does the MSD green wire connect to from the wires coming out of the distributor? Does the MSD green connect to the coaxial center wire or sheathing wire? Or does it even matter which one I connect to?

Steve: ANSWER: You are right in that the violet & green wires conduct the trigger voltage to the MSD. This is phase sensitive and must be connected correctly otherwise the car will not start or run poorly. Connect the center conductor to the green wire and the shield to the violet wire.

O.K. new coil checked wires runs good seems rich. The problem seems now I have a high idle 1..4k won't lower with idle screw checked all vacum lines no leaks. I think it must be very rich . I will lean it out and see what happens.

The idle is still high and the engine is still rich. Before I go and try to do huge rich/lean adj do you think the wur is sticking ?

Have you checked your timing? If it's advanced, it will idle higher.

You should dyno the car to get the A/F ratios right.
