Smart Tuning

Every Smart model, engine, and controller we can tune, 1998+.

Smart tuning at Rapid Racing

We support 24 Smart vehicles across 5 models, covering model years 1998+, through AutoTuner. That includes diesel, electric, gasoline powertrains and 10 engine and transmission controllers.

Each Smart 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.
