JB4 Performance Tuner for Fiat Abarth

Power gains of up to 40whp and 40wtq on a factory vehicle without the risks of flashing!

Now includes the JB4PRO adapter and free app built in! The JB4 is a plug and play tuner that attaches to two easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag.

Installation is very discrete and unlike flash remaps which are quick to install but can never be fully removed with a JB4 the vehicle is never aware it’s making more than the factory boost or power levels. Fuel economy during normal driving is unchanged and it’s compatible with all driving modes including towing.

Unlike other less advanced systems, the JB4 includes CANbus functionality allowing it to take in critical engine data directly from the ECU for real-time tuning. The data includes pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, fuel trims, gear, and much more. Other tuners without CANbus are not able to even monitor this critical engine data no less incorporate it real-time into their tuning algorithms. CANbus allows the JB4 to provide huge power increases with unparalleled power delivery.

The JB4 includes multiple maps including those for 91 octane, 93 octane, factory tuning, VALET mode, E85 mixtures, and unleaded race gas. In addition, it offers boost by gear settings to improve launches, the ability to read and delete fault codes, and much more. The JB4 is made in the USA and includes a 5-year warranty.
