If you are looking at this controller or have been referred here, welcome to professional tuning & calibration. This controller is a reference system used by professional tuners and calibrators worldwide. If you need to be sure of your values, need a wide ranging air/fuel ratio, want to check your other hardware, or are tuning on high dollar platforms, then this is your go to meter. No bells & whistles, no display, nothing more than needed. The display is optional and the AFM1500 offers serial communication and daisy chaining if these options are important to your application. CAN based hardware is available as well.
ECM makes the calibration cells used in professional laboratory environments, product development & validation, & emissions testing. These cells frequently run into the hundreds of thousands of dollars and ECM is the go-to source for high end combustion monitoring equipment.
The AFM1500 Air-Fuel Ratio Monitor is a tool for the calibration, monitoring, and closed-loop operation of fuel-injection and carbureted engines. Exceedingly simple to hook-up and operate, the AFM1500 comes complete with sensor, harness, module, SMB cables, operator's manual, and an exhaust boss and plug. The AFM1500 has both a 0 to 5V analog signal linearized in AFR and a SMB interface. The SMB interface allows serial communication with as many as sixteen AFM1500 modules using a single RS-232 type serial port from a computer and is fully compatible with ETAS INCA software. AFR, FAR, Lambda, %O2, and module status can be read from each module using the SMB interface. The AFM1500 provides unmatched measurement range, accuracy, and speed-of-response in a compact, lightweight package and is an essential tool for any in-vehicle powertrain development program.
