Product Details

Not for sale or use in the state of California.

The legendary Burger Motorsports JB4 module is one of the simplest and most dramatic modifications you can perform on your A90 Toyota Supra. Whether this is your first modification, your only modification, or the finishing touch on your build, the Burger Motorsports JB4 is exactly what you're looking for. Simple, plug-and-play installation can yield results of up to 80whp gains with standard pump gas in a stock Supra. Even greater horsepower and torque can be achieved with bolt-on modifications, higher octane, and boost adjustment with the optional BMS Data Cable (ES3514851) or Smartphone Wireless Connect Kit (ES3514868).

The JB4 features CAN-Bus connectivity for more advanced tuning, direct AFR control, advanced safety systems for boost, air/fuel ratio, fuel trims, engine knock, boost mapping by gear for improved traction, integrated water/meth control, and much more. The unit can be used with Burger's JB4 Bluetooth Connect kit providing for full in car engine parameter display, map switching, and adjustments.

Simply put, the JB4 is as simple or as in-depth as you want it to be - a true jack of all trades.
