Drop-in BLE modules that pair with the Microdyno app. Get clean RPM straight off the ignition coil and live air-fuel ratio from a wideband O2 probe — no microphone tuning required.
Compact BLE module that streams every ignition edge at sub-millisecond resolution. The app derives instantaneous RPM directly — no audio processing required.
Wideband AFR sensor module. Streams live air-fuel ratio over BLE to the Microdyno app. Based on WBO2.
Both sensors in one package: the MicroDyno-RPM module plus the MicroDyno-Lambda with the Bosch LSU 4.9 probe included. Live RPM and AFR side-by-side in the app.
