How does the Eco Diesel and Sprinter tuning work?Updated 3 days ago

For these vehicles, you can either purchase a bench flash or a flash tuner.  Both options require a degree of mechanical knowledge, the bench flash requires physical work to remove and replace the ECM, and the flash tuner requires technical knowledge to extract and load calibrations using a windows-based laptop. 

Ensure you unplug the AdBlue/SCR/After Treatment Module before reinstalling your bench-flashed ECU

All NOX modules must be unplugged

DPF pressure/temp sensor must be unplugged

EGR valve must be unplugged

Intake throttle valve must be unplugged.
