The JB4 is an easy to install plug and play tuner that attaches to sensors in the engine bay and works with your factory ECU tuning to remap boost, timing, and fueling for optimal performance and reduced turbo lag. Includes full SENT sensor technology required for properly tuning the latest Audi platforms. Includes full CANbus allowing the JB4 to access and incorporate all engine data in it's tuning strategies, incorporate unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lubrication and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost. Includes fuel control for ethanol mixture mapping. Fully compatible with FREE JB4PRO app for on the fly map changes, data logging, firmware updates, and much more. 

Revision 2 now includes an integrated boost control connection which can be optionally connected for higher power applications. You no longer need to purchase a separate BCM module for this!

What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way, the JB4 separates itself from the competition with much more advanced connection points and processing, including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade and is sold in over 67 countries worldwide.

Is the JB4 a real tune?

Yes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock/flag your ECU.

Great coffee grinder!
Color: Silver
Amazing product. Easy to use and has different grades of grinding. Zero noise compared with an electric grinder and more control of the results (consistent). His size and weight make it portable and easy to carry.

Quite good as a start grinder
Color: Silver
Very good burr grinder with very functional adjustments. Holds the perfect amount in 1 go for my pour over setup. My only critique is that is has 3 unconnected hopper sections that are quite small and hard to hit. I have to be very careful to not spill and one can fill before the other 2 causing some difficulties closing the crank, but it just takes some self adjustments to get around. Overall I'm very pleased with it for the price.

Nice Grinder at a Great Price
Color: Black
I bought this to use primarily as a travel grinder and found that it is great for every day use. It is not meant for large amounts but it is perfect for single, smaller brewing situations. The grind selection worked well and I "dialed" the proper ground size for my single sized pour over coffee maker.
