Power gains of up to 70whp and 60wtq This plug and play tuner 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. 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.Installation is very discrete and unlike flash remaps it quickly removes without a trace when needed.
Fuel economy during normal driving is unchanged. Compatible with all driving modes.JB4 adds functionality with a plug and play OBDII CANbus connection allowing the JB4 to take in critical engine data directly from the ECU.
Including pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, 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.
The result is huge power increases with unparalleled power delivery.The JB4 also features multiple maps based on this expanded engine criteria, smoother partial throttle performance, additional engine safety systems such as lean run or over boost, more advanced logging for those wanting to experiment with different fuels and E85 mixtures, boost by gear to improve traction, the ability to read and delete fault codes, and much more to come via free firmware updates. Made in the USA.
