Power gains of up to 40hp and 50tq to the wheels on a stock vehicle
This plug and play tuner attaches to two easy to access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. It features a 64mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. Power gains on the 1.5L Civic Turbo motor are up to 50 horsepower and 60 torque (40hp and 50tq at the wheels).
Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes.
The system is fully CANbus equipped allowing the tuning to take in advanced engine data for mapping, logging, and diagnostics. Data channels include boost, timing, air/fuel, fuel trims, throttle, knock control, and much more! Made in USA. 5 Year Warranty.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.
