Description
This plug and play tuner attaches to easy to access sensors in your Lexus 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.
For the IS200 power gains are up to 45 crank horsepower and up to 45 crank torque over stock, at the default map1 setting. With race gas or E85 mixtures higher power gains are possible. Boost is adjustable using a BMS Data Cable or Bluetooth adapter. Includes fully OBDII based CANbus operation for unrivaled tuning performance, features, and functionality.
Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged.
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.
