a more inexpensive option.

The ARC1 Air/fuel Ratio Calibrator provides precise adjustment of air/fuel (A/F) ratio over the entire operating range of an internal combustion engine. It is especially useful for re-calibration of modified engines. The alteration or addition of turbochargers, superchargers, intake manifolds, fuel injectors, fuel regulators, throttle bodies, intake plenums, Mass Air Flow (MAF) or Manifold Absolute Pressure (MAP) sensors can alter the A/F ratio calibration. The ARC1 gives the user a convenient way to set the A/F ratio for rich, lean or stoichiometric operation over the entire RPM and load range.
The ARC1 provides a means to achieve a best fit straight line approximation to the desired air/fuel calibration curve. It gives the user the ability to make these adjustments without a PROM change in the ECU. Furthermore, these adjustments can be made by the driver on-the-fly to optimize the air/fuel ratio for the current driving situation.
An optional +5V output is available which may be used to supply the reference voltage needed for a dedicated MAP sensor. The ARC1 is typically used in conjunction with a precision air/fuel ratio meter such as the Split Second ARM1. The air/fuel ratio meter provides the required information needed to properly set the ARC1 front panel controls.<ul><li><a href="http://www.splitsec.com/products/arc1/arc1ds.htm">http://www.splitsec.com/products/arc1/arc1ds.htm</a</li></ul>
