Haltech Nexus T1 ECU + Honda OBD1 Plug 'N' Play Adapter Harness

Developed by Tuned By Shawn to give the OBD1 Honda market a budget standalone solution without the budget compromises. This kit pairs the all-new Haltech Nexus T1 ECU, successor to the Elite 550, with our proven Honda OBD1 plug and play jumper harness for a true plug in replacement of the factory ECU. No cutting, no splicing, no rewiring the car.

You get everything a chipped or reflashed factory Honda ECU offers, plus dramatically deeper user customization of tables and tuning strategies, modern NSP software with WiFi and USB-C connectivity, and room to grow into boost, flex fuel and full engine protection.

Every kit includes our full stock mapped base map, dyno developed in house, so your Honda starts, idles and drives right out of the box before you ever touch a laptop.

Important Notes

Direct fire conversion kits: we recommend the Nexus T2 combination for direct fire conversion kits. The T1 will work with some functionality loss: naturally aspirated vehicles will be able to retain A/C, however boosted applications will not.

Manual transmission vehicles only. The Nexus T1 does not support drive-by-wire throttle, which is no limitation on cable throttle OBD1 platforms. Additional sensors such as a CAN wideband or flex fuel sensor are available separately.

Emissions notice: Haltech products are designed and sold for sanctioned off-road and competition non-emissions controlled vehicles only. It is the responsibility of the installer and user to ensure compliance with all applicable local and federal laws.
