Welcome to Green Diesel Engineering! GDE provides engine and transmission control unit re-programming that provides large percentage gains in fuel economy and power while maintaining a smoke-free exhaust and respect to all component limitations.
Our core service is the ECO tune for the Jeep Liberty CRD, best for stock vehicles.

The full torque ECO tune and the HOT tune are optimal for KJ CRDs equipped with an aftermarket torque converter.
We have several options for obtaining a tune including shipping your ECU to us for tune install, have us create a clone ECU to swap with your stock unit, or download the tune yourself using our newly released flash programmer tool. The programmer tool can be loaned out or purchased and it will read/clear fault codes as well.
