VR Tuned BMW ECU Flash Tune BMW M3 E46 3.2L CSL 04-06

Crank Horsepower Ratings: Stock Power: 360HP | 273ft/lbs Tuned Power: 381HP | 288ft/lbs With the VR Tuned ECU Flash, basic bolt-on performance parts will not require a retune of your ECU. Adding parts such as an exhaust, headers, air filter, will all adjust with the tune. Custom features to remove CEL's from cat inefficiency codes or raise the rev limiter may be available upon request. If you add higher octane fuel, the ECU will adjust accordingly. Further custom tuning is available with provided datalogging or dyno sheets. Our tuning is used worldwide. We can provide you a tuned file no matter the octane you get or the environment you live in. All ECU flashing is done via the OBDII port. We provide you the cable and all you need is a Windows base laptop or a dual booted Mac with windows installed. There is no need for an internet connection, minimum processor requirements, or worrying about bricking your DME. You can flash your ECU at your convenience without incurring any downtime where others require the removal of your ECU. The VR Tuned flash client exports out your original file so you may flash your car back to stock at anytime. The flash client saves your ECU information in a recovery mode if you incur any issues during the writing process so you can easily restore your file. Basic scan tool functions that can view trouble codes and clear them are part of the software. The flasher can read the entire file or just the programmable section. If you have any questions about VR Tuned, please contact our friendly support team! For reference, this ECU is a Siemens MSS54 and can be OBDII flashed.
