Fuel-It S55 BMW (CPI) Charge Pipe Injection Kit

Advancements of S55 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 S55 CPI kit addresses this limitation by adding extra fuel injectors in the charge pipe to supplement fuel volume and take stress off the high fuel pressure system. Connected to the low fuel pressure system using high-quality plug and play AN lines and included fittings it allows fuel to be injected into the engine directly raising the overall fueling limit. Includes CNC machined couplers that screw into charge pipes with an 1/8" NPT bung. For those equipped with a JB4 the FSB controller is used giving the JB4 full dynamic mapping control and safety. For those running flash only we suggest the Split Second AIC Universal controller which we preload an unlocked CPI map on. Both are fully plug and play solutions.
