I would like to just say thanks to all the staff at Dobeck Performance for their help on the AFR+. The AFR+ is the easiest thing to tune and it allowed me to make peak horsepower on my vehicle. Thank you.....View More
The AFR+ brings together two technologies within one system to make it the most powerful, user-friendly tuning device on the market. AFR+ combines an EFI controller with a wideband O2 sensor and AFR gauge to provide a user instant fuel trimming ability and feedback about their vehicle's state of tune.....Learn More about the AFR+
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 Bypasses OX-023 and OX-024. Your stock O2 connections need to be disconnected and the bypasses installed.
Factory injector connections DO look different from the Dobeck controller connectors, but the male and female connections will plug in ok.
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.
