REV LIMITS
The Controller allows you to program two rev limits; one for an over-rev safety and another that
provides a low limit for use as a hole-shot, or two step limit.
RevLO This is the low rpm limit that is designed to be used while staged at the starting
line. It is activated when the Blue wire is connected to 12 volts. When there is
no 12 volts on this wire, the High Rev Limit is active. It is adjustable in 100 rpm
increments from 2,000 - 12,500 rpm.
RevHI This is the high, or over-rev rpm limit. It is active whenever the Blue wire (RevLO)
is not connected to 12 volts. It is adjustable in 100 rpm increments from 2,000
- 12,500 rpm.
STEP RETARD (Sw Retard)
A step retard will provide an adjustable amount of retard at a specific moment. This is ideal when
using nitrous oxide. The amount of retard is adjustable from 0° - 15° in 1° increments. The retard is
activated when the Pink wire is switched to 12 volts. Default is 10°.
IDLE TIMING CONTROL
This is defaulted at Control DISABLE. When switched to ENABLE, the controller will alter the ignition
timing constantly to search for the best idle qualities.
Note: This is a function of an ECU controlled system and
should be enabled when used with an OEM EFI
application.
TIMING CURVE MODULES
The PN 6010 Controller is supplied with six modules that
plug into the side of the housing (Figure 3). The modules
are labeled Curve 1, Curve 2, etc. By plugging in one of the
modules, the timing curve will be set with a pre-programmed
curve upon power-up of the Controller. (Removing the module
while the engine is running will not affect the timing curve.)
Figure 4 shows each of the
timing curves.
Note: Any updates that
are made using the
PC software will
be overridden if a
module is left plugged
in during power-up of
the Controller.
