With ECUWEST’s Jeep JK Wrangler 3.6i Pentastar ECU Remapping you can expect awesome gains, which is remarkable given this is a naturally aspirated petrol. These results are from tuning only, no other modifications were made.

We can also supply, fit and tune superchargers for the Pentstar 3.6i.

Our Jeep JK Wrangler 3.6i ECU Remapping also improves drive-ability and economy. The process requires the vehicle to be at our workshop (Or your closest ECUWEST dealer) for just the day. Our specialist tuners set the vehicle up on our All Wheel Dyno for a baseline dyno run. We then through our iterative tuning process, tune and revise the tune until it perfectly suits your car and its modifications. All this is done to a safe industry standard ensuring maximum reliability and longevity.
