The HPC Methanol injection controller provides variable flow rate control for methanol / water injection systems utilizing a high pressure injection pump. It is intended for turbocharged or supercharged applications.

Using a universal 2-5V sensor voltage as a input, the controller allows for low methanol flow rates at lower boost pressures and increased flow rates at higher engine loads to ensure optimal ratios and performance. This version is suited for attaching to a throttle position sensor (TPS) or accelerator pedal position sensor (APPS), the controller will then respond proportionally to the throttle position. This controller is also well suited for DC mass air flow (MAF) sensors. This controller will not work on PWM or frequency based MAF sensors.

-Tuning is made easy with just two adjustment knobs

-Compact size of 2.3 x 1.7"

-Includes wiring harnesses and wire terminals for easy installation

-Supplied with instructions

The power indicator LED on the front panel doubles as a circuit status display, alerting the driver to disconnected sensor input wires and broken or shorted pump wiring for additional peace of mind.

This controller uses 2 wires to measure sensor voltage unlike our competition that uses one. This way the HPC controller can account for possible ground offset voltages and get accurate readings every time.

Includes a ground triggered low fluid level wire which will turn the green indicator lamp to amber to notify you of low fluid level. This can be connected to a level switch or in some cases directly to your OEM windshield washer fluid low level switch.

The controller may also be used as a simple on/off control for those that do not desire variable flow rate but want the convenience of in-cabin and on-the-fly control.

Available for 2, 2.5, 3, 4, and 5 bar MAP sensors as well as a 2-5 volt universal model. Custom min and max voltages are available, contact us for details.

This kit includes the controller, a switch, wiring harness and terminals. It does not come with a pump, tubing, fittings or reservoirs.
