About the System

The Everglade RPM ECO Limiter is an entirely electronic product that enables most vehicles from 2002 to have a permanently set top RPM limit combined with a reduced throttle output. This has proven to be an effective method to reduce wear and tear on vehicles and It offers fuel economy savings to vehicles that may not benefit from having just a top speed limiter installed i.e. vehicles not predominantly travelling at higher speeds. The RPM controller is usually set towards the top of the vehicle torque curve to allow useable performance without putting the engine and transmission under unnecessary strain. The throttle output can be decreased by a percentage that helps reduce the rate of acceleration and dramatically reduces the amount of fuel used in the process.


Key Features:

•   Single set top engine RPM e.g. 3000 RPM

•   Throttle output can be decreased

•   Reversible - Can be removed by our engineers 

•   E Mark Certified



•   Reduction in vehicle emissions output

•   Increases in fuel economy

•   Reduction in vehicle and engine wear and tear

•   Protection for fleet operators – Duty of care
