Tiggy iii is a compact Bluetooth fuel gauge that fits almost anything with a fuel line: microlights, paramotors, boats, bikes and cars. A flow sensor in the fuel line measures consumption in litres per hour and the app works out exactly how much fuel is left and how long it will last, so there is no tank to drill and no float to go wrong.

The gauge talks to the free BigArrowHome app on your Android phone or Wear OS watch, which gives you live fuel figures alongside flight and trip information, buddy tracking, an SOS feature and free updates for as long as you own it. The software is fully functional without the gauge too, with no sales splashes.

Tiggy iii Basic contains 1 x Bluetooth module, 1 x flow sensor and the free BigArrowHome software for Android and Wear watches. Tiggy iii Pro adds an absolute fuel sensor for tank-level readings as well as flow.

Supplied with fitting instructions. Mains power is not required: the module runs from the vehicle supply.

The Tiggy Harley Fuel Gauge is a self-contained round display that reads your Harley-Davidson's own CAN bus and turns the engine's fuel-injection data into a proper fuel gauge: percentage, miles to empty, litres used since the last fill and the odometer, all on a bright 466 x 466 AMOLED touch screen.

It listens only. The gauge never transmits on the bus, so the bike's electronics do not know it is there. Four wires connect it: ignition-switched 12 V, ground and the two CAN wires.

Calibration is done on the screen at the pump: tell it how many litres went in and it learns your tank. When the bike's low-fuel lamp comes on, the gauge re-syncs to that known level, and a fill after the lamp is taken as a full tank, so it stays accurate tank after tank. Developed on a Harley-Davidson Street Rod (XG750A); a built-in finder works out the signals on other CAN-equipped models.

Tiggy CAN BUS Dashboard Studio plugs into the standard OBD-II port and listens to your vehicle's CAN bus (most vehicles from 2008 onwards). Instead of leaving you to compare thousands of hex values by hand, its pattern-discovery system finds the signals automatically, and you build live dashboards from them with drag-and-drop gauge widgets in any web browser.

Full OBD-II diagnostics are built in: read PIDs, check and clear engine codes and read the VIN. Threshold alerts tell you when any signal goes out of range. In read-only mode the interface only listens to the bus and cannot affect the vehicle; transmission features require admin authentication.

Everything runs locally on your Windows 10/11 PC, so your data never leaves your machine. Software updates are free for life with no subscription, and the package comes with a 30-day money-back guarantee.

Hardware: 2 x CAN 2.0B at up to 1 Mbps, USB or Bluetooth LE connection. Protocols: CAN, OBD-II, UDS. Looking for DBC import, data logging, dual-bus routing and code export? See Dashboard Studio Pro.

Dashboard Studio Pro is the complete package: the dual-channel CAN interface, the Pro software and lifetime updates for £199, against the thousands that professional tools such as Vector CANalyzer cost.

On top of everything in Dashboard Studio (automatic signal discovery, real-time dashboards, OBD-II diagnostics and alerts), Pro adds import of industry-standard DBC files for instant signal decoding with scaling, offsets and units; data logging of entire driving sessions in CSV, JSON or Vector BLF format with replay; export of discovered signals directly as Arduino / C code ready for your projects; and dual-bus monitoring, so you can route, filter and modify frames between the two buses.

It is designed for automotive enthusiasts building custom gauge clusters, embedded developers prototyping ECUs and telematics, tuners and performance shops logging dyno data, and educators teaching automotive electronics.

Hardware: 2 x CAN 2.0B at up to 1 Mbps, USB or Bluetooth LE, Windows 10/11, any web browser. Free updates for life, everything runs locally, 30-day money-back guarantee.
