Fuel-It - Charge Pipe Injection (CPI) Kit - BMW / Toyota / B58 | BMS-B58-CPI-1

Advancements of B58 flash tuning and JB4 back end flash maps have removed the software fuel limits but created a new limiting factor, high fuel pressure pump volume. With higher boost targets and E85 fuel mixtures the high pressure pump is not able to keep up with demand resulting in fuel pressure drops that trigger engine misfires, stuttering, and limit your overall performance.

The Fuel-IT B58 CPI kit addresses this limitation by adding an extra 7th fuel injector in the chargepipe to supplement fuel volume. Connected to the low fuel pressure system using high quality plug and play AN lines and included fittings it allows fuel to be injected in to the engine directly raising the overall fueling limit. Includes a CNC machined coupler for an easy install that is compatible with the factory chargepipe. For those equipped with a JB4 the FSB WMI controller is used and for those running flash only the Split Second universal controller is suggested. Both are fully plug and play solutions. JB4 provides free firmware updates designed around CPI control and the Split second controller comes programmed with an unlocked base fuel map which you can adjust if needed.
