HEMI SWAP PENTASTAR PWM FAN CONTROLLER

For all the guys that have HEMI swaps and have been battling overheating or overall lack of proper fan speed controls, we have the solution for you.

EZPWM FAN CONTROLER

This module ties directly into the ECU data can bus wires and will monitor engine coolant temp, AC pressures and engine RPM. It will then use those to control a PWM Pentastar fan base on engine temp and AC pressure. This unit is programed to more closely match the needed fan speed of a V8 compared to a factory setting. This unit controls the fan directly and does not require the TIPM for fan control.

Its a simple 5 wire hookup and the module itself is about the size of a standard relay.

OPERATION:
When the unit is powered up the PWM fan will run at a low Idle speed. This help keep air moving and makes the fan respond faster.
The module will monitor the engine temp and will command the fan to the desired %.
205 degrees = 30%
215 degrees = 50%
220 degrees = 75%
230+ degrees = 100%

This unit will also monitor the AC pressure and will command higher fan speed based on AC system needs.

You can also add on up to 2 additional inputs that can be positive or negative controlled. These can be set to command the fan speed for override switches or other applications.
