HKS AFR Fuel Computers

The HKS AFR is a fuel-adjustment device that regulates the air/fuel ratio by changing the airflow voltage output to the vehicles factory computer. The AFR was designed for vehicles that are lightly tuned (intake, exhaust system, etc.) and need only slight fuel adjustment. The 12 setting adjustment indicator allows the user to enrich or lean the stock fuel settings by approximately 1.0 A/R point in either direction (richer or leaner). Type-L is designed for vehicles that utilize an air flow meter.

606/09/2004The S-AFR was easy to install, and it's slim dimensions made finding a mounting place easy. It didn't work as expected though. It says it's a universal computer, but it wasn't compatable with the signal from my vehicle's Mass Air Flow (MAF) sensor. I have a '00 Pontiac Grand Am, which uses both a MAF and MAP sensor. The MAF uses a Hertz signal, while the MAP uses a voltage signal. I tried hooking it into the MAP signal and it seemed to work properly, but the service engine light came on. Also, my car uses the MAF for primary fuel enrichment calculations, so the HKS unit wasn't able to solve my fueling problems as expected. I sold it to someone with a car that it would work better on.
