AEM 30-0334 X-series wideband

So i purchased this AEM that plugs into the obd2 port and the guage reads as should but when i start to scan the channel just disappears...if i had any hair left i would have pulled it out...i tried changing to the 4110 guage and the 03-x3xx still no data...any help would be greatly appreciated. 2017 C7 TSP stage 3 cam,A&A

Once you connect to the vehicle in the scanner, click "Repoll for supported parameters" under the "Vehicle" menu bar button.
Not sure it's a fix, but worth a try.

AEM has a little video on their website and on youtube you can follow too.

Thanks 5FDP worked as should...thanks again!

I'm having the same issue. 2017 Camaro SS 1LE, AEM ODB2 connection. Gauge is working fine. Updated to latest version of HP Tuners. Connect to car, read for all, add new channel AEM Uego 1 selected, it adds it and disappears. Tried beta version. Called AEM, stated it is a known HP Tuners firmware issue (He did not sound convincing). Tried adding with car on, standing on my head, eating ice cream.

Thoughts?

Thanks, new to this.... Tim

I think the channel you selected if for a 30-0300, connected via the prolink.

the obd2 WB is not selected in the external lists, it is in the vehicle data like a normal GM pid u will have to find it in the normal pid list under fuel, or if not then u may have to change the pid and or ecu number for the hpt to pick it up, if its numbered same as another pid it wont show it

Thanks let me try that.

Yup its under unknown folder after you repoll the car with it running. The ones that are labeled already are for the analog inputs into the MPVI2 Pro. You're going to need to add the one that says reports WB under unknown.

Just search for "WB" and it will become apparent what I am talking about.

Attachment 109005 Should look like that. May need to connect vehicle, repoll for supported parameters before it shows up. I have the 30-0334 wideband as well.

^^ yup this is the correct way to add the AEM through the OBD2 port

I?m having this exact problem. 2004 Silverado 2500, I have tried every ecu channel, along with all those on both but rates and the other option. I can not get this channel to show up in hp tuners at all under the engine-fuel-afr options. I have watched every video on how to do it, I have read at least 10 threads in the forum, and nothing has worked.

See my answer in the other thread.
