FCC1 Frequency Calibrator and Clamp

Online data sheet below

Description:

The FCC1 Frequency Calibrator and Clamp is designed to condition the output of frequency based air flow meters such as those used on late model GM cars and Karman Vortex. The FCC1 is especially useful for re-calibrating modified engines. The alteration or addition of turbochargers, superchargers, intake manifolds, fuel injectors, fuel pressure regulators, throttle bodies, MAF sensor or MAP sensor as well as a variety of other components can alter the air/fuel ratio. The FCC1 provides a way to set the air/fuel ratio for rich, lean or stochiometric operation over the entire RPM and load range.

A secondary feature of the FCC1 is that it will clamp the output at a designated frequency. When the frequency of the flow signal reaches the internally set clamp level, the FCC1 maintains a constant output frequency at the clamp level as the input frequency rises. This is useful in modified engines that generate higher flow levels than stock. The frequency clamp will avoid activation of fault codes by the ECU and is compatible with OBDII.

The FCC1 is intended for use in kits for specific applications and may be ordered with fixed calibration. No user adjustment is provided. Throughout its entire control and clamping range, the FCC1 always produces a clean, undistorted signal which the ECU can reliably read.

Features:

	May be ordered with fixed calibration and clamp level
	Avoids fault codes due to excess flow readings
	Compatible with OBDII systems
	Clean, undistorted output signal
	Internal transient voltage suppression for high reliability
