Frequently asked questions.

If your vehicle has an OBD-II port, MiniGauge works — that's virtually every car, truck and SUV sold since 2008 (and many European models back to 2001). MINI (R50/R52/R53) and BMW (E39/E46/E53/E83/E85) also get dedicated fitment guides and model-matched mounts.

No. MiniGauge only reads data from your OBD-II port — it never changes your engine's programming. No tune, no flash, no coding required.

It's genuinely plug-and-play — most installs take about 10 minutes. Plug the harness into the OBD-II port, tuck the wire, and drop the gauge into a standard 52mm pod or a model-matched mount. No cutting, drilling or splicing.

Your choice — MiniGauge does both. In wired mode it plugs straight into the OBD-II port for constant power and data, perfect for a clean permanent install. In wireless mode the gauge pod runs on its own built-in battery and connects to your car wirelessly, so there are no wires on the gauge at all — and you can move it between cars.

In wireless mode MiniGauge runs on a built-in all-day battery, and it recharges with any USB-C cable. Because it isn't tied to one harness, you can move it between cars in seconds — take it from your daily to your track car and back.

Over 20 live parameters, including boost, coolant temp, intake air temp, oil temp, battery voltage, RPM, speed, throttle position, fuel trims, timing and AFR — switchable on the fly, with custom color alarms for any value.

Yes. MiniGauge reads OBD-II fault codes with plain-English descriptions and lets you clear them right from the gauge.

Yes, but they're not read from the OBD-II port — they require the MiniGauge Sensor Box, a separate add-on (sold separately) with dedicated sensors. Add it to display true oil pressure and oil temperature right alongside your live OBD-II data.

No. MiniGauge is a standalone gauge — it powers on with the key and displays everything on its own AMOLED screen. No phone, no subscription.

No. It draws very little power (under 0.5A) and powers down with your ignition, so it won't run your battery flat.

The 1.6″ AMOLED MiniGauge, an OBD-II plug-and-play harness, and a quick-start guide. Model-matched mounts and the oil sensor box are available as add-ons.
