Everything the cockpit needs.
One round display, a web panel that manages it, and a data pipeline built for the track.
01 · Live Telemetry
Live gauge, 10+ channels.
The round 360×360 display cycles through boost, AFR, RPM, ECT, IAT, battery voltage and more — always readable, always fresh. A freshness indicator shows when a value hasn't updated recently, and peak-hold tracks the hardest number you hit.
- check Color-coded arc, blue → yellow → red
- check Per-channel freshness / stale detection
- check Peak-hold per session
02 · Web Panel Management
Full control from a browser.
Choose a theme, pick exactly 8 of your available sensor channels, and pin the firmware version your gauge should run — all from the panel, no cables required.
- check Theme + splash selection
- check Pick 8 of 10 sensor channels, reorder them
- check Pin / follow-stable firmware control
03 · Hotspot OTA Updates
No SD card. No cable. Just park.
While parked, the gauge joins your phone's hotspot for a short window, checks in with the panel, and pulls down any pending config, theme or firmware update — SHA256-verified before it's applied.
240 samples · 2 minutes @ 2Hz · auto-captured, no button needed
04 · 2-Minute Data Logging
Never miss the moment that mattered.
The gauge always keeps a rolling 2-minute buffer. Press Get Log to save it manually, or let an alarm condition trigger an automatic save the instant it happens — both sync to your panel for review.
05 · Alarm Thresholds
Set the line. Get warned before you cross it.
Configure high/low thresholds per channel — EGT ceiling, oil temp floor, boost spike — and the gauge flags it immediately on-screen, with the triggering event auto-saved to a log.

06 · Two Product Modes
One display, your setup.
FlashPro-BLE mode
Already have a Hondata FlashPro? The gauge connects over Bluetooth LE and reads its live ECU stream — no extra hardware.
SMNGauge ECU mode
No FlashPro? The SMNGauge ECU sensor module reads oil temp, EGT, boost, ethanol % and fuel temp directly and sends them over ESP-NOW.
