Advanced VAG Tuning: Nexus S2 Plug ‘n’ Play Kit for VW/Audi 1.8T
The Haltech Nexus S2 Plug ‘n’ Play Adapter Kit brings the power of the Nexus platform to the popular VW/Audi 1.8T AWP engine (2001-2006). The Nexus S2 is the successor to the Elite 1500, offering faster processing, on-board Wi-Fi, and integrated wideband control. This kit is the ideal solution for tuners looking to extract maximum performance from the 1.8T platform in vehicles like the Mk4 GTI, Jetta, and Audi TT.
Seamless Integration
The adaptor harness plugs directly into the factory ECU connectors, allowing the Nexus S2 to take control of the engine without cutting wires. It supports the factory Drive-By-Wire throttle, variable cam timing, and CAN bus dashboard integration (developed on 2003 Beetle). The kit includes an external air temperature sensor to convert the system to Speed Density, eliminating the restrictive factory MAF sensor. With the Nexus S2, you gain access to advanced motorsport features like launch control, traction control, and rolling anti-lag.
