Kuhn tuning at Rapid Racing
We support 1 Kuhn vehicle across 1 model, covering model years 2018+, through AutoTuner. That includes diesel powertrains and 1 engine and transmission controller.
Each Kuhn 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.
