This is a MSD PN 7562 Programmable Launch Boost Controller for a Blower or Turbo with 4 Bar Map Sensor probe (Race Pak Probe), ProCharger 8 Pound Blow Off Valve that works with any ignition system.
The system is like new without splices to wiring harness, original disc for Windows PC and Instruction manual. It works with any CO2 bottle. It works on timers, so when you release the trans brake or two step it will apply CO2 to allow the set percentage of boost out the valve then applies more CO2 until the valve is completely shut for 100% boost. I used it on small tire and big tire pro mod. It worked flawlessly with a MSD Grid and Digital ignition system. The system records runs, so you can overlay ignition timing curves to control wheel speed.
There is an optional second ProCharger Blow off Valve and 5 Pound CO2 bottle at an additional cost. If you need to reduce boost by more than 8 pounds you add a second blow off valve. Contact me for pricing on those items at email@example.com
