The Elite 550 is a simple yet powerful ECU ideal for basic 4 to 8-cylinder or 1-2-rotor engine applications. Suitable for either naturally aspirated or forced induction engines the Elite 550 gives you full control over fuel delivery, ignition timing and boost levels. This robust, competitively priced ECU features an environmentally sealed, waterproof case, 4 fuel and 4 ignition channels and a 4 BAR internal MAP sensor. T he Elite 550 ECU is now paired with the new Nexus Software Programmer (NSP) that brings levels of functionality and user-friendliness never seen before in an engine control package. Together they offer true cutting-edge technology to tuners and performance enthusiasts worldwide.
