Initial programmed settings. Suggest to tune in the Yellow and Red modes first and then move the Green/Blue mode to 10.5 (+25) to run auto-tune. Closed loop has the following AFR targets: Yellow @ 14 and Red @ 12.5
Controller comes with O2 Plugs OX-021. Your stock O2 connections need to be disconnected.
Installation of Injector Harness is front and rear specific - Your bike is equipped with Harley's Engine Idle Temperature Management System (EITMS). When engine temperature exceeds 284° F, the EITMS will turn off the rear cylinder fuel injector. Idle speed will be maintained, however the rear cylinder will become an "air pump" which will work to cool the engine. Dobeck controllers power-up through our channel 1 injector connection. The connector pair with double pinned RED and YELLOW wires is channel 1 and should be connected to the FRONT cylinder.
