PLX Devices SM-AFR Wideband + MultiGauge Link Combo PN: CMLINKAFR

I have one SM-AFR sensor module with Multi-Link. I have two O2 sensors, one each bank of cylinders. The IOS app connects reliably, and gives O2 readings while I drive. Since I can only read one sensor at a time, I will tune one bank of cylinders, then swap sensors and tune the other bank. This does everything I want it too.

EL producto es muy bueno, se instala muy fácil y la sonda va muy bien. El problema es de la aplicación que se cuelga a veces, otras no conecta y en coches carburados oscila un poco pero eso es normal.Edito a 1 estrella pues ha dejado de funcionar, es imposible conectarlo y he probado en 2 smartphone distintos y nada. Parece que he tirado el dinero 😔Deberían mejorar la aplicación para evitar que se quedara congelada a veces.......

Contrairement à ce qui a été écrit sur d'autres commentaires, la société est très réactive aux demandes (un petit oubli de l'adapteur bluetooth) réponse sous 24h et envoi dans la foulée, reçu 48h après... bravo...De plus l'appli marche parfaitement contrairement à ce qui a pu être publié...Je recommande

The wideband works great. I replaced my stock narrow band and I am feeding it from the 0-1v output. By replacing my stock narrow band and having no gauge to mount installation was quick and easy. I thought being Bluetooth it might have lag or have glitches but I have had no problems with my iPhone. Response time is quick which makes it perfect for tuning my fuel injection.

I had very high hopes for this product, but it's been a terrible letdown. Simple install, but PLX documentation is vague, poorly written and regarding the multigage link connections - inaccurate. troubleshooting info is absent from the website, and nobody answers the phone at PLXThe device was installed 100% correctly by a 30 year master mechanic and does not work. Not even a little bit. Display freezes at "0 Lean" or 14.6 and the app crashes constantly.A waste of money and I'll be returning it to PLX for a refund. Then I will buy a replacement wideband O2 from a company that shows actual commitment to making a useful product - and supporting customers post-saleSorry for the unflinching and hard words, but money and time are precious - and people shouldn't have to waste either.
