The Speed-Buster Power Module is a simple plug and play E70 X5M/X6M S63 power upgrade with three performance modes controlled via Bluetooth app (free download via Android and Apple app stores). The Speed-Buster delivers big power gains with no downside. The installation is simple - just 3 sensors and power leads - making it the easiest power gain you'll ever do. By sending modified signals back to the engine computer, the Speed-Buster tricks the computer into safely raising the boost. And with careful programming of operational tables, the Power Module doesn't trigger torque limiters, monitors, or limp mode, which means safe power that won't kill your engine - or warranty!
Inside the Speed-Buster tuning box is a sophisticated programming module, tuned specifically for the S63 engine on Speed-Buster's MAHA dyno. All development, tuning, and production are done in-house at their German facility. Speed-Buster's programming works seamlessly with the factory ECU to give an impressive increase in power with factory-levels of driveability and smoothness. All factory overboost protections remain in place and the system can be uninstalled at any time. A bypass plug is also included that allows stock operation without component removal if you want your BMW to appear stock. The Power Module works independently from the factory BMW ECU so it's unaffected by software updates and revisions, and all OBD diagnostics and service functions are untouched.
Installation is fast and easy - simply unplug the factory connectors for the designated sensors on the S63, plug into the Speed-Buster harness, and plug the Speed-Buster connector into the sensors. The harness uses factory-type connectors for a positive and weatherproof connection and an OEM appearance.
The free app is downloaded from your phone's app store. Use the app and Bluetooth connection to select from 3 power settings
- Eco = better fuel economy
- Sport = mild increase in torque/power
- Sport Plus = maximum boost levels
It also features an adjustable warm-up timer
- set the amount of time for the engine and oil to warm up before full boost is available. An Active screen displays boost level and RPM so you can monitor the operation and performance of the Speed-Buster in real time.
