MSD Ignition Start-Retard Control
This timing control is the direct result of MSD being at the races and listening to what racers want. With the large number of engines running locked-out timing, racers wanted a simple way to retard the timing during cranking plus have a single stage of retard available for high rpm or nitrous.
The Start/Retard Control lets you choose either 10 or 25 of retard during cranking only. The timing will retard only while cranking and returns to the set mechanical timing once the engine starts and you release the key or until the engine reaches 1,300 rpm.
Along with the start retard, this Control also has a single stage of retard. This retard can be activated in times of nitrous to prevent detonation or at high rpm to achieve a little more top end. The amount of retard is adjustable with plug-in modules and is activated by a single wire that can be connected directly to a nitrous solenoid or a micro switch on the shifter. The Start/Retard Control is easy to install and program and i supplied with 2, 3 and 4 modules. It must be used with an MSD 6, SCI, 7, 8 or 10 Ignition Control.
