Automotive Technology Group Inc. was incorporated in California with a singular focus: bringing rigorous engineering standards to automotive operations. For nearly two decades, we've remained true to that mission from our headquarters in Costa Mesa.
We don't build generic software; we engineer precise technological integrations that bridge the gap between mechanical complexity and digital efficiency. When dealerships and fleets need systems that simply cannot fail, they call ATG.

Purpose-built systems for high-performance automotive environments.
Integration of OEM and custom diagnostic protocols for deep-level vehicle communication, fault isolation, and module programming.
Network topography analysis, packet sniffing, and custom gateway module development for complex vehicle networks.
Bridging physical vehicle data with shop management software, automating telemetry capture and service record generation.
Safe, documented procedures and hardware interfaces for module flashing, coding, and parameter adaptation.
Robust, oil-resistant, high-availability shop networks designed specifically for heavy diagnostic tool usage and large file transfers.
Integrating modern diagnostic reporting with older shop management systems through custom middleware and hardware bridges.

Proprietary diagnostic interfaces that extract, analyze, and interpret deeper vehicle data layers than off-the-shelf scanners.

Integrated workflow platforms connecting service bays, parts inventory, and customer management into a single frictionless pipeline.

Custom firmware and hardware solutions bridging aftermarket equipment with complex OEM digital architectures.
No guesswork. Every integration is meticulously tested against stringent tolerances before deployment to your shop floor.
Our solutions embed directly into your existing operational workflows without causing costly friction or downtime.
Automotive environments are hostile to fragile tech. We build robust systems meant to survive heat, dust, and continuous use.
We aren't just software developers. We understand CAN bus architecture, shop dynamics, and what mechanics actually need.
