Elevate your 2012 Mercedes E63 with a precision ECU tune from ECMTuner, based in Moonachie, NJ — serving the NYC metro area and remote clients nationwide. Our custom calibration delivers real, dyno-proven gains: go from 503 HP / 437 lb-ft stock to a thrilling 593 HP / 515 lb-ft — that's +90 HP and +78 lb-ft of torque.
Select your stage and pay securely. We confirm your vehicle details within 24 hours.
We ship an OBD cable to your door, or you ship us your ECU for a bench flash. Your choice.
Flash takes 30–60 min. Your stock file is always saved. 100% reversible at any time.
We exclusively tune BMW, Mercedes, Porsche, Aston Martin, Lamborghini & more. Deep expertise beats generalists.
Every calibration is developed and validated on the dyno. Real numbers — not marketing estimates.
Not local to NJ? We ship a flash tool anywhere in the US. Tune from your own driveway.
We work within safe parameters for your engine. Your car's longevity is as important as power gains.
