MSD Programmable Shift Controller

Product images may differ from actual product appearance.

Now you can set different rpm points to trigger the shift solenoids. Any transmission configuration can be used (up to a six-speed) with either a 12-volt activated solenoids or pulse signal activated solenoids. Each solenoid activation is programmed in 100 rpm increments. A shift inhibit circuit compensates for tire spin. Works with most any ignition system that can provide a tach signal. Programmable from a PC with MSD's Pro-Data+ Windows based software or with the optional hand held Monitor (P/N 121-7550).
