The 02 sensor "simulators" are used in the marine industry, where it is
impossible to mount an 02 sensor in the "wet" exhaust of many high-performance
late model inboard boats. In fact, a friend of mine bought a new MasterCraft
just last year, with a 350 horse 350 LT1 (Corvette) engine, which uses some
sort of electronic "black box" to feed signals to the ECM based on throttle
position, rpm's, water temp, vacuum, and who knows what else, in order to
determine the proper stoichiometric ratio being run through the engine. I
agree with the statement that it should be fairly straightforward for someone
with electronic skills to create such a "black box" which would allow someone
to eliminate the 02 sensor.
