Haltech Nexus S3 ECU

Part Details:

Once a build outgrows the factory ECU, the Haltech Nexus S3 is a standalone that takes over fuel, ignition, boost, drive by wire and even automatic transmission control from one box. Haltech built it as the successor to the Elite 2500, keeping everything that platform did and adding an onboard wideband controller, Wi-Fi, dual drive by wire and far more logging capacity on the faster Nexus processor. It suits engines with up to 8 cylinders or up to 4 rotors, in racing applications where advanced race features and data logging are needed.

The Nexus S3 is tuned with Haltech’s NSP software over USB-C or Wi-Fi, works with the Haltech Connect app, and connects to Haltech dashes and expansion devices over two CAN ports. Haltech products are sold for off-road and competition use only and are not legal for use on public roads in emissions controlled vehicles.
