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.

A full service listing is posted under the "Calibration" link and "Service Offerings".

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 (flash) tool can be loaned out or purchased and it will read/clear fault codes as well. The flash tool is the preferred option as this eliminates vehicle downtime and no removal of any vehicle hardware.

For Australian customers we have a local distributer, Murchison Products, to handle orders and provide local support. Tunes are only sold with the flash tool in Australia and the price is $950 AU. The price for transmission tune is $500 AU. There is a link to Murchison Products website further down the page.

Tune Purchase Options
We have a 60 day money back guarantee if you are not completely satisfied with the tune, we will re-flash your ECU back to stock configuration free of charge. If in the future a dealer inadvertently updates your controller, you can send it back to us and we will update it with the tuned calibration.
