Get Real AFR Data Directly Through OBD2 – No Guesswork, No Risk

If you’re tuning with HP Tuners, EFILive, or DiabloSport, your data is only as good as your AFR signal.

The AEM X-Series OBD2 Wideband Gauge 30-0334 gives you true wideband air/fuel ratio data streamed directly through your vehicle’s OBD2 port—so your logs are cleaner, your tuning is safer, and your power gains are real.

No more syncing external logs.

No more inaccurate narrowband guessing.

Just accurate AFR data inside your tuning software where it belongs.
