APS’s high idle engine switches and corresponding kitting provide consistent high power to on-vehicle systems when the vehicle is not in motion (at idle). To comply with environmental regulations in recent years, automotive manufacturers have decreased vehicle engine revolutions at rest to reduce carbon emissions. Lowered idle RPM has indeed led to fewer emissions—a fine trade-off for most consumer vehicles in typical situations. However, for specialty vehicles with work to do at idle, low RPM can cause problems. APS high-idle controls increase engine-idle RPM to ensure consistent electrical power to the aftermarket systems required to get the job done.
