The AEM 30-0334 OBDII X-Series Wideband for FlashScan V2 is finally available,

[dr.mike]

Hi All.

AEM has finally introduced the new 30-0334 version of their OBDII enabled wideband ( Formerly, the 30-0333 ) that supports single and dual widebands in FlashScan V2. This is based on the re-flash code that has been tested over the last few months. So, the x-series widebands can now connect, directly, via the OBDII connector, as opposed to using the 0-5v analog outputs. On CAN enabled vehicles. This is a HUGE improvement.

The new EF1 and EF2 PID settings allow for two widebands to share the same OBDII connector via a master/slave configuration. This bit of tech has been the source of the delays. The single-wideband-only version was just completing testing when the new dual-wideband capable version was 1st introduced. So, fun fun fun, we got to start all over. But, definitely worth it, if you want to monitor 2 banks.

Beware that there are still some of the older 30-0333 units ( that only really support brand"H" scanners ) in the pipe. So, be sure that you get the newer part number. In case there is any confusion, I received the following info from the AEM guys:
"The two units can be distinguished via the hold-both-buttons-while-applying-power boot-up message (0333 vs 0334) or a PN decal on the rear of the unit. "

If you get them directly from AEM, I'm pretty sure you will get the correct 30-0334. Not sure what dealer/distributor stock look like, at the moment.

It was fun getting this to work. I hope it helps

Thanks Dr. Mike! Appreciate your help and diligence working to get this done for EFILive customers like me!

Here is my sample file UserCalculatedPids.ini that uses both AEM -334 widebands, the BEN pid selects the leanest bank on the fly

( that file was generated and saved from within the V8 pid editor ( go Scan->Config->Calculated Pids, create a Group (upper pane), create a Pid (lower pane) ) )

we initially/briefly tested this using dr.mike's -334's at AEM (Hawthorne) using Martin's 2010 Camaro (CPR Engines, Gardena)

( dr.mike edited the AEM embedded firmware to make dual AEM's communicate with FSV2, to understate what he did )

I just want to point out that ALL 30-0334 have this "tweaked" firmware that dr. mike developed for AEM. So there is nothing that needs to be modified on a true 30-0334 AEM UEGO wideband, it will support this Calc.PID out of the box.

30-0333 units will NOT support this.

Hey Joe.

Is it possible to use this info to help make a ben factor pid for the E92 controller like we were working on a while ago??

I'm noticing that there are no DMA commanded fuel pids available for the new DI controllers and it's a huge pain in the ass

to calibrate a maf or VVE table without the ability to auto correct the maps with an accurate Ben factor pid.

I tried to use a commanded lambda pid but had no luck.

Is there a way we can do this? Should we start a new thread? I'm sure others will be needing it too.

Thanks

After you select the AEM UEGO Bank1 for the trans controller, you then use the pids GPM.WO2S11 and GMP.WO2S21.

Does this WB have an output for non can vehicles, or is it only for the later model PCM's? I need a WB, but don't plan to try to do anything with a can vehicle currently.

Answered my own question. I guess I read thru the info too fast, and didn't see.......

The 0334 supports CAN-bus as used on later model vehicles (from 2007+)... i.e. does not support J1850 VPW (what 0411 uses).

The 0334 also has analog 0-5V output, see what dr.mike says about it.

It does not have serial comm output.

Is this AEM Wideband compatible with the LS1B 411 PCM?

I should have asked this before I ordered it I guess......
