AEM Wide band disappears when pressing record

[Alex14SS]

I just got a wide band with the obd2 port connection & when I connect it it logs on the little screen but on the computer it disappears and won?t log anything. I?ve tried the beta, rescanned, and nothing.
Anyone know what could be the problem? Thanks. I have an MPVI2 Pro

Mine does that as well. I added wb equipment ratio 1 I believe in channels and it reads what my gauge reads.

JMO but the AEM WB 30-0334 has never worked well with HPT. I have the same WB but without PRO version of HPT. Dr. Mike helped me with a work around last summer and I had it working fine. With spring around the corner, went to install last night and no channel support what so ever. The generic channel for aem 30-03XX does not work either. I submitted a support ticket and was told to update to PRO as only solution. Makes me believe support does not have a handle on 30-0334 setup or realize unit reads from obd2 port..

Have one for several years now with no issue. Occasionally I have to re-poll and that takes care of it.

I reached out to Dr. Mike. See his suggestions below!! I did have a setting wrong.. Bottom line, I reset the gauge settings, repolled and found the channel WB EQ RATIO #1 (SAE) per his direction. FWIW, the channel location had changed for me from last summer. Not sure why..

Big thanks to Dr. Mike!!

from the OBD2 menu:

Next is to select the correct channel. You SHOULD be able to select the "WB EQ RATIO 1 (SAE)", from the "OBD Controller: Unknown/Engine/Fuel/OPen & Closed Loop/Oxygen Sensors" tree, now. Since it is one of the 2 PIDs reported.

Do NOT select the "WB EQ RATIO 1" from the "External Inputs/AEM/X-Series UEGO (30-03xx)" tree. Repoll..

followed this and no luck. ive reset guage back to factory, watched and read tutorials for 3 hours straight and still nothing. made sure drivers on laptop are current etc. im not making any progress. any other ideas?

Contact Dr. Mike! Well worth it. He can read a diagnosis file and make recommendations..

Hey thanks! Ive hit him up!

I had the same issue on my surface. No idea why, but when I turned off Bluetooth it fixed my issue. Now my wideband appears every time. Just something quick to try.

[LS ROB]

thanks. sorry for the late response but i have since gotten it added to the channels with the help from the DR.

Who is this Dr? My ?WB EQ Ratio 1? is greyed out with a broken link and I don?t have the ?OBD controller? folder in the channel settings.

I am assuming this is all done in HPT?

"returning gauge to factory settings"????? I am using the same AEM gauge and just looked at the instructions that came with it and did not see any operating instructions. I'll check it out more thoroghly in a minute.

Does the same hold true if I am not setting up in Lamda?

I experienced some odd behavior with WBO2 datalogging, but slightly different than the OP.
I'm using an MPVI3 with the Pro Link hooked up analog (red wire) to an AEM 30-0300 WBO2.

Sporadically the WBO2 data will freeze, all other data streams fine. I will have to go through a process of stop logging, disconnect, remove the channel, add the Prolink Analog Input channel back, then re-transform it to EQ before it will start recording WBO2 data again. At this point it's been an annoying 50/50 chance on when it might occur.

Just throwing this out there in case it helps anyone, or if anyone has any better solutions.
