Mercedes-Benz E450 ECU Tune — Stage 1

AMR Performance develops Mercedes Benz E450 ECU software as 3 separate files, not one calibration reused across a range. Installation is comport pro -or- dealer flash or wireless via comport ipro (obd). These cover the E-Class (W213) chassis, each written for that car's engine and gearbox combination. The list includes transmission (TCU) software and CPC tuning, which can be run individually or together. All current files are built for 91/93 Octane pump fuel — no race fuel and no hardware changes required. Every calibration listed here ships as a Stage 1 tune; the power figures for each are on its own product page.
