Up for sale MSD 8625 Timing twister. Was used on my show car for about 3000 miles. Worked perfect on my supercharged nitrous meth application.

The MSD Timing Twister ignition controller plugs into the stock wiring harness and gives you complete control of ignition timing advance and retard. Advancing the timing can produce improved acceleration and better fuel economy. The timing advance function allows up to 9° of advance. The timing retard feature allows the simple installation of a nitrous system as well as adding boost from a turbo or supercharger. Used alone, the Step Retard function can pull up to 30° of timing.
For boosted applications, the optional MSD 4-BAR MAP Sensor, PN 2314, is easily connected to the Timing Twister. This sensor will measure up to 45 psi of boost, to which the user can program up to 30° of retard. When used in conjunction with the Boost Retard function, the Step Retard is limited to 18°. Combined with the Step Retard, this means the Timing Twister can retard timing ignition up to a maximum of 48°. The Timing Twister does not modify ignition timing at idle or low engine speeds. Above 1800 rpm the timing advance and retard functions become active and ramp to the full timing value over several revolutions of crankshaft rotation. The timing is also ramped back to stock over several revolutions when the engine rpm falls below 1500 rpm. A MODE switch is included to allow the user to disable the unit and utilize stock timing. It can also be used to disable only the retard functions while leaving the advance timing function active. Note: The MSD Timing Twister will allow the user to advance the factory ignition timing in order to make more power. However, the factory ECU also advances timing at part throttle under light load for emission reasons. It is not recommended to advance timing more then 2° when driving around town under part throttle conditions. At the race track when the vehicle is going to be under full throttle more timing can be applied. If at any point detonation is detected (knocking or pinging sound from the engine) this timing is too far advanced and needs to be retarded in order to prevent engine damage.
Note: It is crucial that premium fuel (91 octane or higher) be used whenever advancing ignition timing. Failure to do so may cause severe engine damage due to detonation.
