I am happy to announce we are releasing the JB4 to the public. The hardware has been finalized but the software/firmware is evolving and many new features will be added. It is highly recommended
that you get the USB cable so you can update the unit as we release new features
How about up to 180hp and 155tq to the wheels on a fully modified car on race gas and/or methanol injection? The JB4 features a simple plug and play installation harness and built in deletion of hidden "tuner detection" codes. Compatible with all ECU versions.
As part of the new release promo we will be offering a sale on PnP units.
