Whats the maximum amount of timing I can retard with the Pro Mag Timing Retard?
The largest retard chip we make specify for the Pro Mag Timing Retard is 30º these can be purchased at the MSD trailer or special ordered from the Pro Mag Department. They only cost $8 each. The Pro Mag Timing Control was initially designed with a maximum of 15º of retard, but at the racers request we have pushed the unit to 30º of retard. By doing this the calibrations have changed slightly from 15º to 30º here are the values: 16º = 16º, 17º = 17º, 18º = 20º, 19º = 21º, 20º = 22º, 23º = 23º, 24º = 24º, 25º = 25º, 26º = 26º, 27º = 27º, 28º = 28º, 29º = 29º, 30º = 30º Note that a 21º and 22º modules are missing this is because the calibration is NOT Linear at this point. The unit was not intended to work past 30º and it was also our intent to replace the unit with the Pro Mag Programmable Controller that would be very accurate from 0º to 35º. But the Programmable unit is not approved for use by the NHRA.
