What does a soft touch rev control do?

It makes the ignition misfire to limit rpms.

It randomly takes out cylinders to control the rpms at the rev limit. SO you are not loading up a few cylinders.

Like said, it drops random cylinders, and the processor will not take out the same cylinder two cycles in a row. With the old studder boxes the ignition was in effect shut of and on repeatedly to keep rpm's from going over a set limit. This caused cylinders to load up with fuel and very often a big ol bog at the launch, or dead cylinders for the whole pass. The 'soft touch' was developed by Mallory if I remember correctly and is now a standard (in some form by numerous names) in all rev limiting ignitions.
