The ScienceofSpeed AEM Series 2 Engine Management System (EMS) for 1991-94 NSX is a programmable plug-and-play engine management system that allows total standalone control of fuel, ignition, VTEC, along with other engine functions.
Compared to the discontinued Series 1 EMS, the Series 2 EMS offers increased processor speed, enhanced sensors stability, USB connection, FlexFuel tuning, engine protection features, and other benefits.
Note: factory traction control is not supported. The AEM EMS has a limited engine acceleration traction control system (wheel speed sensors are not used) to calculate loss of traction. Requires individual vehicle setup and configuration, but depending on tire and road conditions, the settings must be changed.
