Designed specifically for heavily modified vehicles the new JB4PRO system includes built in Bluetooth, built in ethanol sensor processing eliminating the need for a separate ECA, built in CPI/WMI control eliminating the need for a separate FSB, onboard data-logging memory, plug and play o2 bias wires, built in wiring ports for our 10 bar pressure sensors for low fuel pressure and/or coolant pressure, optional plug and play EWG harness add on, and includes many additional features to be unlocked in the future via free firmware updates! JB4PRO is the ultimate tuning tool for those looking to push their cars to the max!
For less modified cars we still recommend purchasing the less expensive base JB4 system. If you are planning for more extensive modifications like heavy E85 mixtures, CPI/WMI, larger turbos, etc, go for the JB4PRO variant.
