This user friendly touch screen flash tuner allows you to read the information from the engine computer using the diagnostic connector located in the cab and takes only minutes to complete. Once the stock engine tune file has been read you can now unplug the tool and continue operating the machine as normal. We specifically engineer a very easy to use communication program that allows you to connect your programmer to a windows enabled computer and read the stock tune file from the programmer and email to us for upgrades.
