About Hitachi BEM54C tuning
The Hitachi BEM54C engine control unit is supported in 5 models from Dacia, Renault. We read, modify, and flash it with AutoTuner, then verify the result on our Dynojet 424xLC2 in Jenison, MI. A custom calibration optimizes fueling, ignition timing, boost, and torque limits for your exact build.
