SKU: G5 2step

This add on kit for BMW N54 engines allows your JB4 to "2step" the engine (cycle power to the coils) to build boost when not under load. Useful as both a noise maker for both manual and automatic transmissions, and for launching with manuals transmissions. Also allows No Lift Shifting (NLS) for manual transmission cars.

The relay kit requires a JB4, back end flash map, and BMS data cable or JB4 mobile kit. Automatic transmission vehicles do not need the clutch wire.
