The John Deere S670 is a combine harvester powered by John Deere’s 6-cylinder engine. Its displacement is 9.0 liters and outputs 320 HP. This machine is popular in Australia, New Zealand, the USA, South America, and South Africa.

Controlling the John Deere S670 engine is a Phoenix L14 ECU. Therefore this ECU / ECM can be programmed via the diagnostic port with an Alientech KESS V2 or Dimsport Genius.

Once the machine’s ECU is read out, Alt Tune has the ability to re-calibrate its maps. Common results from re-tuning the S670’s ECU is an increase of 15% in power and torque. This brings the power output up to 368 HP. This allows the machine to perform its job with ease when it is heavy crops or tough terrain. Often up to 8% fuel savings are seen, for instance.
