CarBahn 798 HP Stage 2 Performance Controller | BMW F9X M5/M8 2020 - 2025 F90, F91, F92, F93

CarBahn Performance Controller (CPC): The CPC is a plug and play ECU that increases boost pressure in turbocharged cars to dramatically increase HP and Torque. The unit has selectable maps through a Bluetooth app on your smart phone. You can download these apps for your smartphone through the Apple App Store and the Google Play Store. These maps are designed to accommodate different octane fuels for additional increased performance. You can choose between 91, 93 and 100 Octane. As with all CarBahn products an optional powertrain warranty can be purchased. If you want to trade your CarBahn Performance Controller in for software in the future, there is a $500 upgrade fee and if you purchased the warranty, it is transferable to the software at no additional charge! Doing it yourself: A note on self-tuning tools. There are now programs available that you can buy to tune your car yourself. Many of these tools come with canned programs. Be careful as tuning a high output engine requires tremendous knowledge and experience to extract maximum power without damage. Emissions legality: A note on down pipes (removing the catalyst). We have run back-to-back dyno runs with the cat on and off and the power gain is much smaller than most people claim usually around 11hp. We all need to breathe the air. It is difficult to get your car its required emissions test without catalyst and it is illegal. High boost with stock engine: We have seen many damaged engines as result of making too much power with a stock engine. While modern engines are very reliable, it is easy to add large turbochargers and water methanol injection and break the engine. On the F9X, maximum safe power on a stock engine is 800 lb-ft flywheel torque. CarBahn makes high performance engines designed to handle more power. More information is available on this web site.
