Via OBD or on the bench?
Across the 125 engines in the database the EDC17C64 is worked via OBD in 119 cases and on the bench (ECU removed and opened) in 3: it depends on the software version. Each engine page shows the method.
How the remap is done
- The ECU is read and the original file is saved.
- MasterTuning develops the Stage 1 file on that software, in Foggia.
- The file is written to the ECU and faults and parameters are checked.
- Road test. The original file stays saved and can be put back.
How much it costs
The Stage 1 price depends on exactly this: OBD read or bench. The figures are in the guide how much an ECU remap costs; on your engine page in the database you see the price of the nearest MasterTuning centre before paying.
