I recently locked out my distributor and bought a retard start module to help with starting. The car start fine BUT, when it's running the tach jumps around. When I bypass it, the tach is fine. The tach wire is in the same location never moved!!

When I bypass the module and the car desides to start being that it is advance, the tach is fine.

I know that it has a good ground and my wire connections are very tight. Any thoughts??????:confused:

After talking with MSD Tech and some testing.......bad retard module. Getting it exchanged.

Heck even the exchanged one did the same. Get this........MSD told me to send the one I have (8982) back to them and they will give me 8987 for an even swap!
