The ZZPerformance pump controller has been in the works for nearly 4 years. After many failures and months of exhausting in car testing, we have a design we're comfortable selling. Here's how it works:

The unit plugs inline with the TPS sensor on your throttle body (no cutting). Then it starts the pump when you start the car.

     The controller monitors the throttle position to determine engine load and adjusts the pump flow accordingly.

FAQ

1. What pumps will this work with?

The Bosch pump and the Rule pump we sell. It will not work with the GM pump. This controller was not meant to be used with the SS intercooler which works best with a positive displacement pumps (like the Flojet).

2. Why is it so expensive?

-The R&D involved in this unit would merrit a cost much higher.

-Gains are suprising with boost air temp drops up to 30 deg over a car without this controller.

-It allows the reliable use of the Rule pump saving a lot of money over the GM.

3. It is hard to install?

No, installation is very simple.

4. How does it work?

A microprocessor monitors the pump, the TPS voltage, and the car's electrical signal. There are many safeguards put into place to ensure proper operation. The controller uses pulse width modulation to vary the speed of the pump.

5. Where do the gains come from?

In testing our intercoolers on the car we found some very interesting things. With the pump flowing at full speed, the water in the intercooling system can rise to more than 50 degrees over ambient. This is without even going into boost and translates into much higher outlet temps as well as melted Rule pump housings. This controller lowers that temperature close to ambient. This has the benefits of higher horsepower. In addition, the pump will be silent.

6. What does it do?

It runs the pump at 5% during idle and ramps to full speed at 50% throttle. It runs the pump for 60 seconds after the car is shut off to maximize intercooler system cooldown.

7. Will it work on my car?

It works on all throttle bodies with a TPS sensor. It will not work on drive by wire setups.
