Haltech Nexus R5 + LSx Non DBW Terminated Harness (HT-195406)

LSx Non DBW running a Haltech Nexus R5 VCU is one of the strongest combinations in standalone engine management, and this kit delivers both halves at once: the ECU plus a terminated engine harness with labelled, pre-terminated wiring that gets the engine side of the job done in hours.

What You'll Feel

A car whose entire electrical and engine control layer behaves and gets logged: DBW throttle mapped your way, onboard dual wideband holding closed loop accuracy under boost, and native torque, boost, and traction strategies without add-on boxes. An LS swap wired and controlled properly starts on the first key turn, idles like stock, and takes power adders without drama.
