Compliance Controls AFR-9R air/fuel ratio controller offers the same simplicity as the AFR-1R model. Non-intrusive installation. Streamlined menu-driven navigation. But with more setpoints, you get even tighter control. The AFR-9R controller offers nine setpoint targets, based on a combination of three RPM settings and three manifold pressure settings. As your engines load conditions change, your AFR-9R continues to make sure it is in the best possible operating range. It also includes manifold pressure and RPM sensing technology. If your site is facing tightening regulations, changes in ambient temperature, big load swings or gas quality/pressure changes, the AFR-9R is the right choice. It’s simple air/fuel ratio control with more flexibility.
