MSD Three Stage retard controls allow you to retard your ignition timing in three different stages. You can activate one retard for a nitrous stage, and another at top-end in high gear for more mph, and still have another module left over for dual-stage nitrous systems. When activated together, the retard amounts are cumulative, so you get the total of the three. For example, if you pull 2 degrees, then 4 degrees on the second stage, and another 2 degrees at top-end, the total retard is 8 degrees (2+4+2=8. In addition to the individual retard stages, the Three Stage retard controls have an optional start retard function that retards the timing 10 or 25 degrees while cranking the engine. This makes starting high-compression engines with locked-out timing, such as crank trigger systems, much easier. These units easily connect to your MSD Ignition and can be triggered from points, electronic ignitions, crank triggers, or magnetic pickup distributors. They're supplied with a 2, 3, and 4 degree module, and must be used with an MSD 6, SCI, 7, 8, or 10 Series ignition.

just wondering do you still have this ?

I sure do

if I am running 1 stage and want to pull 10 degrees will it do that ? I keep seeing advertised pulling 2 or 4 degrees on each stage . im thinking you can pull any amount off 1st stage with correct module up to a total amount ? also need start retard , running locked out timing at 32. Did you have any issues with rotor phasing?
