About Marelli 10JA tuning
The Marelli 10JA engine control unit is supported in 2 models from Alfa Romeo. 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.
