OBWB8m · 8-channel wideband controller
Eight wideband channels. One honest picture.
The OBWB8m reads up to eight wideband O₂ channels at once, in lambda or AFR, and serves them straight to your browser — no proprietary dongle, no desktop install. Log a full pull, then pull the CSV.
- Embedded web server — configure and monitor from any browser
- Logs straight to your computer over Wi-Fi — CSV, limited only by your laptop
- Full CAN-bus integration — native O₂ data to your ECU
- Bosch LSU 4.9 and Walker 250-25001 sensor support
From sensor to ECU, in three steps.
Integrate
The OBWB8m ties into your vehicle’s CAN bus, so the ECU receives native wideband O₂ data (lambda or AFR) from all eight channels — no analog workarounds.
Connect
Join it to Wi-Fi and open it in a browser. No dongle, no install — and it’s WPA2 password-protected, so your bench stays yours.
Log
Stream straight to your computer as CSV — capacity limited only by your laptop, not the device. Broadcast to the ECU and log at the same time.
