About Bosch M17.8.7 tuning
The Bosch M17.8.7 engine control unit is supported in 4 models from Polaris. 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.
