CLA250 Tune — Stage 1

AMR Performance develops CLA250 software as 3 separate files, not one calibration reused across a range. These cover the CLA (C117), CLA (C118) chassis, each written for that car's engine and gearbox combination. Every file here is ECU calibrations. Installation is wireless via comport ipro (obd) or obd flash. 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.
