Product Details

An additional tune file to use with the plug & play Bosch Motorsport ECU in the E46 M3. When you buy the Bosch ECU from us a tuned file is included but we can also provide you with additional files (the Bosch ECU can hold up to three files, switchable from the Sport button on the center console). We can tune for specific modifications such as cams, headers, and even supercharger kits, and also fuel type, throttle, rev limits, or anything else that you need. Since the Bosch ECU is a true motorsport ECU, it is tuneable on its own using a laptop and the Bosch expansion harness. You can make your own files and changes on the fly. But if you did not purchase the expansion harness or want one of our pre-made dyno-tuned files, add this item to your cart. A Turner rep will be in touch to discuss your needs.

Requires plug & play Bosch Motorsport ECU system.
