Burger Motorsports JB4 Performance Tuner for the 2023+ Nissan Z

Burger Motorsports has been manufacturing the world famous JB4 Performance Tuner for over a decade and their success continues with the release of the JB4 for the all New 2023+ Nissan Z.

The JB4 performance tuner for the new 2023+ Nissan Z shows dyno proven power gains of up to 100hp and 120tq to the wheels on a stock Nissan Z!! The plug and play unit attaches to two easy-to-access sensors in the engine bay and works with your factory DME tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag. The JB4 manipulates the ECU boost control signals allowing it to modify boost levels but does not manipulate the ECU manifold boost reference, allowing your ECU to properly map timing and fueling for the higher boost levels. The end result is something that runs as smoothly as stock only with higher boost targets under heavy throttle. JB4 features a 64mhz processor allowing sensors to be sampled 1000 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.

OBDII CANbus provides performance mapping, data logging, boost by gear, the addition of option fuel wires for AFR adjustments and on the fly map changes with the use of the optional blue tooth feature. The JB4 is not VIN locked like other tuning software on the market, which means it can be removed without a trace, swapped between cars and resold down the road.
