Re: Racepak Sportsman Help
RPM is read off the tach wire to the ignition box. Check the connection, shouldn't be a butt connector but soldered and terminal into ignition box. Do you have a tach connected also or reading rpm through intelligauge or RP dash? Could be a conflict with tach also, but much less likely. I would check wire for damage and faulty connection

Re: Racepak Sportsman Help
Had a similar problem with mine & I called Holley. The 1st thing they said was RF interference. Put new plug wires on and got a filter (MSD8830) that goes on the coil power wire, fixed.

Re: Racepak Sportsman Help
Sounds like a noise issue. Check how and where the wiring is routed. Stay away from any wires that run fuel pump, water pump, fan, etc. also recheck all your grounds.
