BMS JB4-N55-F Tuner Module JB4 for BMW Engine N55 F Chassis

Description BMS JB4-N55-F Tuner Module JB4 for BMW Engine N55 F Chassis

The JB4 is a plug and play tuner that plugs into 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.

Unlike other tuning systems, the JB4 includes a fully programmable CANbus system, upgradable firmware, and data logging capability. CANbus allows the JB4 to take into account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those into the performance mapping. It can also read/delete fault codes, and includes unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lucubration and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost.

The JB4 offers a lot more performance, functionality, and safety than your average performance chip.

The default JB4 map 1 runs 4psi over stock peak, and tuned maps, including stock and valet mode, can be selected on the fly using a BMS diagnostics cable or JB4 mobile smartphone adapter.

Installation is very discrete, and it quickly removes without a trace when needed. Includes maps for 91 octane, 93 octane, and E85 (ethanol fuel) mixtures. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in USA. 5 year warranty.
