REV LIMITS

There are two rev limits to program with the PN 4217. One for overrev protection and another limit to use

for the launch. Both are adjustable from 1,000 – 16,000 rpm.

LaunchRPM: This provides you with second rpm limit that is activated when the Blue wire is connected

to ground. Once removed from ground, the Max limit is active.

MaxRPM: This is the overrev rpm limit. It will keep the engine from overreving due to a missed gear or

driveline failure.
