The built-in, two-step rev-limiter is managed by an advanced micro-controller. There are two rev limiters—one for high end over rev protection and another activated off a clutch or transbrake to set a launch limit. The adjustments are made with four rotary dials which are adjustable in 100 RPM increments. The spark output of the new box can go up to 535 volts of primary voltage with spark energy reaching up to 135 mJ. The multiple sparks of the 6AL-2 burn in the cylinder for 20 degrees of crankshaft rotation to ensure complete combustion.
