In 1995, Field of Japan introduced its SFC-VTEC and fuel controller to U.S. consumers. It was arguably just the right time. During the mid-'90s, as B- and H-series VTEC engine swaps became more prevalent, tuners became determined to find a device that would allow them to adjust VTEC crossover points without actually cracking open their factory ECUs. For many, the ability to adjust VTEC engagement to a higher point, along with minor fine-tuning of the fuel curve, meant saying good-bye to the factory "bog" that plagued so many. Some enthusiasts used their Field units simply for activating VTEC while using a non-VTEC ECU with their swap. Other features included the elimination of the factory speed governor on Japanese-spec ECUs, peak-hold rpm readout, and a built-in audible shift indicator. Those who sought the assistance of an experienced tuner could realize a smoother powerband with a high-cam crossover point optimized for their particular engine setup. Many eager, self-made tuners did more harm than good though, which is really no surprise, finding neither the proper fuel/crossover combination, nor an increase in power or torque. My how things haven't changed.
Years later, as the demand for more user-friendly tuning devices increased, many companies began producing more advanced units, while standalone engine management systems became much more affordable. This left the Field SFC-VTEC and fuel controller in the not-so-distant past. Gone, but certainly not forgotten. May we always remember.
