The first-gen Renault Twingo has no RPM or coolant temperature gauges, which is annoying on track. So I made TwingoDash: a simple ESP32 dashboard that shows both values and adds LED shift indicators.
A WiFi OBD2 dongle reads RPM and coolant temp from the ECU, sends them to the ESP32, and the ESP32 draws the gauges on a small screen. There’s a bit of WiFi/CAN delay, but for a slow-revving Twingo engine it’s totally fine.
LED logic: Green — OK to downshift Yellow — Revs getting high Red — Don’t downshift Blue — Upshift All thresholds are adjustable in the code.
The project is open source and easy to modify. GitHub: https://github.com/Rusty-Wrench/twingodash #twingo@rstwrnch
