Fuel-It! / Burger Motorsports S55 Charge Pipe Injection (CPI) Kit – BMW M2 Competition, M3, M4 (F87, F80, F82/F83, S55)

OVERVIEW

With S55 flash tunes and JB4 maps no longer bound by software fuel limits, the high pressure pump's volume becomes the ceiling. Push more boost or blend in E85 and rail pressure can drop, bringing misfires and stutter with it. This Fuel-It! charge pipe injection kit adds supplemental injection in the charge pipes, fed from the low pressure system, to raise the overall fueling limit and ease the load on the direct injection system.

CNC machined couplers thread into the charge pipes via 1/8" NPT bungs, and the injectors connect to the low pressure fuel supply with plug and play AN lines and fittings. Choose the FSB controller to give a JB4 full dynamic control and safety over the CPI, or the stand alone controller for flash-only setups.
