03

Off-Road Vehicles

Rugged harness builds engineered for vibration, heat, and exposure.

04

Specialty Projects

Prototype systems and application-specific electrical packages.

Services

Five disciplines, one clean install.

From a bare chassis to a fully calibrated, data-logged system — every service is built to be reliable, serviceable, and documented.

Harness

Custom Wiring Harnesses

Complete custom wiring solutions built around your vehicle, ECU, PDM, sensors, and power requirements.

Integration

ECU & PDM Integration

Integration of standalone ECUs, power distribution modules, sensors, relays, switches, and motorsports control systems.

Calibration

ECU Calibration — MoTeC

Calibration support for MoTeC-equipped motorsports and performance applications. We tune MoTeC exclusively. Intended for off-road and competition use only.

Data

CAN Bus & Data Systems

CAN communication setup, sensor integration, dash configuration, data logging support, and signal documentation.

Custom

Special Projects

Custom motorsports electrical solutions for unique builds, prototype systems, and application-specific packages.

NOTE — Calibration services are MoTeC-exclusive, intended for off-road and competition use only.

Our Process

From scope to install.

A defined process keeps every project predictable, even when the build isn't.

[ 01 / SCOPE ]

Project Discussion

Every project starts with a conversation about the vehicle, intended use, components, timeline, and requirements.

[ 02 / PLAN ]

Quote & Project Plan

Once the scope is defined, LMTR provides a quote and project plan. Most custom projects require a deposit before design, planning, or material ordering begins.

[ 03 / BUILD ]

Build & Documentation

Projects are built with attention to reliability, serviceability, and clean documentation throughout.

Built for Motorsport Use

Our products and services are intended for motorsports, racing, off-road, and competition applications. These systems are not intended for emissions-controlled street use unless specifically stated.

Warranty

What's covered.

Wiring Workmanship

One-Year Coverage

Custom wiring work includes a one-year workmanship warranty. Coverage applies to workmanship defects and does not cover misuse, improper installation, crash damage, water intrusion, heat damage, customer modification, or failure of third-party components.

Calibration & Tuning (MoTeC)

Not Warrantied

Calibration, tuning, and motorsport-use services are not warrantied due to the variable nature of engines, fuel systems, mechanical condition, operating conditions, and customer use.
