Alientech has released KESS3 Upgrade 3.73, adding a new OBD protocol for the Ford and Volvo FoMoCo EEC-VI petrol ECUs. Until now these were handled in Boot mode, so reading and writing through the diagnostic port is a useful step for workshops. Our KESS3 tools now read and write these ECUs over OBD, and the Powergate can also work remotely through the OBD port. The source does not describe the protocol as Beta.
Which ECUs
The release covers the FoMoCo EEC-VI family, listed by Alientech as the ESU 312, 320, 412, 415 and 417. The new mode is OBD, which sits alongside the existing Boot mode. Production years are given as 2003 onward, and the engines named are 2.0 and 2.3 litre petrol, including LPG and Flex Fuel versions. Alientech labels it a KESS3 Protocol Release and gives no protocol name or version. Because OBD is now an option, the job no longer depends on removing the ECU from the car, which was the main hurdle with the earlier Boot route.
Cars this opens up
The vehicles named in the release are:
- Ford EcoSport
- Ford Fusion (USA)
- Ford Galaxy
- Ford Mondeo
- Ford Ranger
- Ford S-Max
- Volvo C30
Engine and year coverage varies by model, so check the exact car against the Alientech release before booking a job.
What it means
For owners of a Mondeo, S-Max, Galaxy or C30 with the 2.0 or 2.3 petrol, a calibration is usually about throttle response and smoother mid-range pull, and on a car that tows or carries a full load it is the low-rev drive that gets noticed most. A healthy engine and service history come first.
For dealers, an OBD route means the ECU stays in the car, so there is no dismantling, less risk and a faster turnaround. Owners can start with our tuning builder, dealers can send work through our file service, and the Alientech tool page covers the KESS3 and Powergate range.
