We support 62 Claas vehicles across 10 models, covering model years 2013+, through AutoTuner. That includes diesel powertrains and 5 engine and transmission controllers.
Each Claas tune is calibrated for your exact hardware and fuel, then verified with real data on our Dynojet 424xLC2 in Jenison, MI, serving Grand Rapids and West Michigan. Not sure which controller you have? Browse all supported ECUs or ask us.
