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. The AFR+ can handle all of your fueling needs or compliment ECU downloads and already installed EFI controllers. The AFR gauge allows you to know exactly how well your tune-up is performing. The EFI fueling allows you to control any necessary fine tuning without spending more money or valuable time.
