BMS Audi & VW Group 8 JB4 Gen3B Beta (A3, A4, A5, Passat & Polo GTI)
True Plug & Play Tuning
JB4 Group 8:
Unlike other tuning systems the JB4 includes a fully programmable CANbus system, at home upgradable firmware, and data logging capability. CANbus allows the JB4 to access engine data to take in to account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those in to the performance mapping. It can also read/delete fault codes, incorporate 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 over heat, run lean, excessively knock, or over boost.
The default JB4 map1 runs 3psi 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 smart phone adapter.
The simple plug and play installation is very discrete and it quickly removes without a trace when needed.
