MSD Soft touch rev limiter

According to the MSD site , the soft touch rev limiter drops a cylinder on 1 cycle and fires it on the next to stop plug fouling.

If this is the case , then the MSD is effectively firing 2 cylinders per revolution instead of 4 per revolution.

If one was to have a broken drive shaft universal joint at full throttle , one would expect the engine with no load and half full power to over-rev and break .

Is this the case , will an MSD soft-touch rev limit actually stop the thing over-revving in the case of a drive-line failure , getting airborn etc ?

The soft-touch rev control will completely stop the engine from going above the RPM on the inserted module. I use a 2-step with one for the t-brake & one for red line. You can be in park with the t-brake activated & still not rev over the 3200 I have in it.

those msd boxes are alot smarter then youd think. it will change the spark profile up to 30 times per fireing event. that would be 10000 changes a sec on a v8 at 5000 rpm. also it will monitor the secondary volt to see if cycler pressures are to high " detonation " and then will automaticly retard timing

When I installed mine (MSD 6AL) they included a 3,000 rpm test chip. With the pedal to the floor it would not go past 3k rpm.
