Aem wideband 30-0334 keep disappearing

Anyone know how to slove this issue? I'm trying to get a remote tune,I add the AEM wideband to the channels and try to the log the car is WB channel dissapears. Also noticed it has a lock sign? with a key next to the AEM but does not have the lock sign when the I don't scan the vehicle . Tried beta and updating hp. Any ideas? 2020 camaro
Edit* I think I was using the wrong channel but I'm sure the correct channel is under engine/unknown devices/and wb eq1 and 2 but these are not on my vcm scanner. Any way to get this to work.

I was tuning a 2017 Camaro SS. I had to make sure the WB was on before I fired up the scanner and connected. If it still deosnt show, repoll.

I have tried everything . Been trying to datalog for 2 days. Put in a ticket and hpt and they are looking into it. Basicly I don't have the wb in the channels. Not sure if I should get arid of the obd wb and get the pro version with a wb wired in.

Does the WB show up in the info log ?
Have you changed any settings on the gauge ?

I don't see the any wb in the log and have changed anything in the AEM gauge. I also just saw where you posted about possiblly having the wrong firmware installed in the wb. I don't have the obd2 option in the gauge but only have can

I have the gauge in my 2016 Silverado and it picks it right up when I re-poll for supported parameters. I used the WB EQ1 channel like it says.

I have no idea what's going on. I have searched every channel and see nothing.

If you have the CAN menu instead of the OBD2 menu, your gauge has the wrong firmware. You need to send it back to AEM to be re-flashed/replaced.

I did hold in the the 2 buttons on the AEM while powering up and came up 0300 so thimk it's definitely the wrong frimware.

I don't know if that test is dispositive. The 30-0334 identifies itself to the scanner as a 30-0300 because the original OBDII gauge was a modified 30-0300. The ID in VCMScanner was never changed.

So, the display, at start-up, might, still, say 30-0300 on a 30-0334. Not, sure.

But, if you have the CAN menu instead of the OBD2 menu, you, 100%, have the wrong firmware.

@ dr.mike you are the man. Ordered a new wideband and everything is working fine now. I'll send my old one back to AEM then eventually run a dual WB set up . Once again I appreciate it
