Most of these advancements are in the all-new ECU, which features a faster processor, a water proof design and measures half the depth of the previous ECU. It also has an upgraded Bluetooth chip that is faster, more reliable and will not drop connection. Finally, we've added more features for the advanced tuner giving you control over cold starts and acceleration, while retaining the simplicity Pro-Flo is known for and proven to deliver. Edelbrock's Pro-Flo 4 fuel injection systems utilize the latest in Bluetooth Mobile Technology - all tuning related functions can be done on your Android smart phone or tablet with the Edelbrock E-Tuner 4 App. The E-Tuner 4 App features an easy to use setup wizard to guide you through the setup process for your specific engine package.
