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 2 x OX-003. Your stock O2 connections need to be disconnected and the bypasses installed.
This system DOES NOT require the welding in of an O2 bung. The Bosch wideband O2 sensor will simply replace the front factory narrowband O2 sensor. An O2 bung cap is supplied with the unit so you may remove the rear factory narrowband O2 sensor as well. The factory O2 sensor connections need to be disconnected, have the O2 bypasses installed and then zip tied out of the way.
