Complete custom wiring solutions built around your vehicle, ECU, PDM, sensors, and power requirements.
Integration of standalone ECUs, power distribution modules, sensors, relays, switches, and motorsports control systems.
Calibration support for MoTeC-equipped motorsports and performance applications. We tune MoTeC exclusively. Intended for off-road and competition use only.
CAN communication setup, sensor integration, dash configuration, data logging support, and signal documentation.

NOTE — Calibration services are MoTeC-exclusive, intended for off-road and competition use only.
A defined process keeps every project predictable, even when the build isn't.
Every project starts with a conversation about the vehicle, intended use, components, timeline, and requirements.
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.
Projects are built with attention to reliability, serviceability, and clean documentation throughout.
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.
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, and motorsport-use services are not warrantied due to the variable nature of engines, fuel systems, mechanical condition, operating conditions, and customer use.
