MSD BTM gives bouncy tach idle???
I have a MSD universal BTM installed on my 1991 TA 305 HEI system. I get a bouncing tach at idle. It seems to smooth out while driving.
I know it is not a strictly tach failure as when I hook up my Jacob's Pro Street instead of the stock coil, the tach works fine.
If anyone has experienced this please let me know.
Thanks.

Yes. MSD told me this or you need to buy their part #8910 to fix it.
I have the Jacob's back on-line and it fixes the problem.
Strange how these things work!
Thanks.
