At the heart of this system lies our exclusive E-Tuner 4 app, complete with dyno-developed base calibrations. Facilitated by a Bluetooth wireless connection, the E-Tuner 4 app communicates seamlessly with the ECU’s self-learning capability, continually adjusting the calibration for optimal performance. The app features a user-friendly setup wizard for a smooth initiation and provides multiple dash displays for real-time monitoring of your engine’s vital signs.
