Understand OBD2 PIDs, adapters, and hybrid signals — without drowning in forums.
A curated knowledge base for European HEV and PHEV owners and enthusiasts. Look up what a signal means, which logging app labels it, and which adapter people actually use on a given platform. This is not a log viewer.
What this site is for
OBD logging looks simple until you mix a cheap adapter, a phone app, and a hybrid that hides battery data behind manufacturer requests. This site is a single, structured place to learn those pieces and how they fit together — not another comment thread.
-
Translate the jargon
Standard Mode 01 PIDs versus manufacturer-specific requests, UDS identifiers, and the names apps invent in CSV exports.
-
Match car, adapter, and app
See which combinations are documented for EU hybrids and plug-in hybrids, and which signals are confirmed versus only reported.
-
Trust the source
Every catalog claim carries provenance. Official standards sit above community notes. You can see confidence before you rely on a PID.
Who it helps
Owners and tinkerers of European-market hybrids and plug-in hybrids (roughly 2010 onward, with the densest coverage from 2015). If you log with Torque, similar apps, or a Bluetooth adapter and want to know what a column actually measures — this is for you.
It is also for people choosing hardware before they buy: which adapter talks to which app, and whether a platform exposes hybrid battery data at all. Pure battery-electric (BEV) diagnostics are out of scope here.
How to use it
Browse or search. Pages stay read-only for visitors. Nothing here plots a trip or analyses a CSV — that is intentional. The goal is a durable reference people return to.
-
Standard PIDs
Complete J1979 list: PID number, name, unit, formula, and explanation.
-
Standards
J1979, J1962, ISO 15765-4, J2012, ISO 14229, EOBD and WWH-OBD.
-
Signals
Canonical measurements such as battery SOC, HV voltage, and ICE baselines.
-
Platforms
Vehicle families and which signals they are known to expose.
-
Adapters
Chipsets, protocol support, and known app pairings.
-
Apps
Logging apps and the column labels they write into exports.
What this site is not
- Not a log viewer, chart, or trip analyser.
- Not a shop and not a paid product page.
- Not an open wiki — you cannot publish catalog rows yourself.
- Not a Discord or GitHub-shaped community dump.
How to contribute
One channel, reviewed by a curator. Send a structured tip (PID hint, correction, platform or adapter note). On this page — and on every catalog page — you can also mark it helpful, unclear, or report an error. Votes do not go live in the catalog.
