SupraStore.com Commentary:

Highly recommended product! Also works on Euro and JDM spec MkV Supras! We have used a few tuner boxes and even ECU flashes and for the average daily driver A90 Supra owner, the JB4 is our primary choice.

Why? Install is quick, performance options via 7 different tune settings, trouble shooting, CEL reader, data logging all make this the ultimate set-up for Supra owners. We include our own personalized install guide as well making it A90 Supra specific.

We have this on our shop car and it is making 400+HP on Map 1 and 450+ HP on Map 3 (93 Octane with a Down Pipe). People ask is the JB4 compatible with Supra's outside of North America? Absolutely, yes! The JB4 we ship is a global application and supports all cars RHD and LHD.

Power gains of up to 80hp to the wheels on a stock vehicle The JB4 is the most advanced and highly featured tuning system available for your A90 Toyota Supra. Power gains are up to 80hp to the wheels (100hp crank) on a completely stock car on pump gas for a B58, gains with bolt on parts, higher octane, and larger turbos are even higher.

The JB4 features a simple plug and play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built in data logging, built in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more. Other more expensive tuners may claim to equal the JB4's technology but upon closer examination lack most if not all of the JB4's features.

Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for those who are interested in logging, adding new features as we post them, etc, we suggest the BMS DATA cable or REV3 mobile phone adapter.

Note we have not developed the in dash commands yet for the JB4 Supra. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.

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.
