Product details

Description

This Tuned By Shawn plug-and-play kit (HT-651254) pairs the Haltech Nexus S3 ECU with the matching Boomslang adapter harness (BF29171) for the 2009-2018 Nissan 370Z (Z34 chassis, VQ37VHR V6 engine) with a manual or automatic transmission. The harness plugs into the factory engine harness where the stock ECU connects, so the Nexus S3 takes over full standalone engine management with no cutting, splicing or repinning.

Frequently Asked Questions

Does this kit require cutting the factory wiring?

No. The Boomslang harness plugs into the factory engine harness connectors, so the stock wiring stays intact and the vehicle can be returned to stock.

Does it need a tune after installation?
