Note: This rpm confirmation only displays when the HEI Gray wire is being used to trigger the
tachometer.
REV LIMITER VERIFICATION
The MSD HEAT HEI Module has an optional built-in Rev Limiter Verification feature. When the key
is in the On position (not cranking or running), an rpm signal is sent to the tachometer to verify the
unit's rev limit setting. With this function users can be sure of their rev limit settings before each drive
To enable this feature, follow the procedure below.
Note: It is important to note that this feature should not be used with EFI systems. When activated,
an rpm signal is sent to the tachometer. With an aftermarket EFI system, this could activate the
injectors causing a flooding situation.
ENABLE REV LIMIT VERIFICATION
1. With the ignition switch in the off position, ground the Gray tach output wire.
2. With the Gray wire connected to ground, turn the ignition on without starting the engine.
3. Hold the Gray tach output wire to ground for seven seconds. (AT LEAST five seconds.)
4. Release the wire from ground before ten seconds have passed.
5. To confirm the process has worked, cycle turn the key On. The tachometer should sweep to the
rpm limit set on the ignition.
To deactivate the verification feature, repeat the process.
Playback Tach: If you use a playback tach, be sure to check the high rpm value prior to turning the
key to the On position. When the key is in the On position, the rev limit will be displayed and may
override the tach memory.
