Mercedes C450 ECU Tune — Stage 1

AMR Performance develops Mercedes C450 ECU software as 3 separate files, not one calibration reused across a range. The list includes ECU calibrations, transmission (TCU) software and supporting fuel-system hardware, which can be run individually or together. Installation is wireless via comport ipro (obd) or mechanical installation by qualified technician. These cover the C-Class (W205) chassis, each written for that car's engine and gearbox combination. All current files are built for 93 Octane / 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.
