Important Notes
Installation should only be attempted by someone who is completely comfortable with automotive wiring.
Professional installation is highly recommended.
Kits 101020-101050 REQUIRE a voltage feed from the vehicles MAP sensor that ranges between 0 and 5
volts, and increases as boost pressure (engine load) increases. If the vehicle does not have a MAP sensor
one must be installed separately. Kit 101005 requires an input from any 0-5 volt sensor, which increases
with increasing engine load, such as a MAF or TPS. Note: some MAF sensors output a digital signal rather
than 0-5 volts. Kit 101000 requires the vehicle be equipped with high impedance injectors, and will not
work with low impedance injectors. Confirm type prior to ordering.
The supplied 10 amp fuse must be installed to protect the wiring and the module, warranty is void if not
installed. The internal over current protection of the module only engages over 35amps, and is intended
only as a backup. See the installation instructions for more information.
Failure to properly follow the instructions in this manual could result in severe personal injury or may
damage the vehicle, either electrically or mechanically. If you are uncomfortable, have a professional install
it for you.
It is advised that tuning be aided by the use of wide-band oxygen sensors, exhaust gas temperature gauges
and engine knock indication systems. Failure to properly install, test and monitor for correct operation of
the controller could result in severe engine damage due to pre-ignition, excessive combustion
temperatures, hydro lock or other reasons. Watch your gauges.
As with any methanol injection system, using a mixture of more than 50% methanol can not only harm the
pump but is dangerous. Mixtures of no more than 50% methanol, mixed with water are generally
recommended. Windshield washer fluid with antifreeze protection generally contains a safe ratio of
methanol to water and may be a good candidate fluid for your injection system. Avoid fluids that contain
solvents and detergents such as bug wash or water repellants.
If the injection pump utilized has a built in over pressure cutoff switch, do not disable this switch without
first contacting the pump manufacture. If the pump does not have an internal pressure relief valve, the
pump may be damaged if its over-pressure cutoff switch is modified, disabled or removed.
