About ecuLink
Remote diagnostics, built for heavy-duty trucks
We build the hardware and the cloud platform that lets fleets and repair shops run their existing OEM diagnostic software on any truck, from anywhere.
Why we exist
Heavy-duty diagnostics has been stuck in the same shape for twenty years: a USB cable, a Windows laptop, and a technician walking around a truck. The OEM software is excellent. The hardware adapter is fine. The shape is the problem — every event needs a person physically next to the truck before any diagnostic decision can be made.
We started ecuLink to change that shape. The VCI lives in the truck. The technician connects from anywhere. The OEM software stays the same. Roadside dispatches drop, multi-yard fleets consolidate around their best technicians, and shops bill more billable hours per senior tech. The diagnostic step in heavy- duty maintenance becomes ambient — always available, always audited.
What we ship
- The gateway. A small, ruggedized device that plugs into a 9-pin diagnostic port. Cellular and GPS built in. Designed to live in the truck full-time.
- The cloud platform. Per-device WireGuard tunnels, role-based access, audit logs, an admin console, webhooks, and a public API.
- RP1210 and J2534 adapter drivers. Install once on the technician's laptop and every heavy-duty diagnostic application — INSITE, DDDL, PTT, ESA, ET, JPRO, Jaltest — picks up the gateway as a normal adapter.
- Free industry directories. A nationwide repair shop directory and trucking jobs board that we run as a free service to the heavy-duty community.
What we believe about diagnostics
- The OEM software is the right interface. We don't build a proprietary diagnostic frontend. Cummins, Detroit, Volvo, Paccar, and CAT have spent decades getting their applications right; we make those applications work from anywhere.
- Remote diagnostics has to be auditable. Every session is timestamped, attributed, and logged. That is a feature, not a side effect.
- Hardware in the truck stays simple. No driver app. No phone pairing. No shop Wi-Fi. The gateway runs unattended for years.
- The platform pays for itself in tow trucks. We price ecuLink against the ROI of preventable dispatches, not against telematics seats.
Who we are
ecuLink is a product of Autonomo Inc. (autonomo.ai), an autonomous-vehicle and heavy-duty mobility company. We're a small team of engineers, mechanics, and fleet operators based in the United States. We work with the people who actually wrench on Class 8 trucks and the people who keep fleets moving — that's where the product roadmap comes from.
