AEM X-Series OBDII Wideband UEGO AFR Sensor Controller Gauge

[joecar]

Yup, that's working; did you have a calculated PID to convert the lambda value to AFR you'd be willing to share?

The attached calc_pids.txt file defines the pid CALC.WO2S11.AFR... please use this pid to display wideband AFR

( and use SAE.WO2S11.lambda for tuning, e.g. use CALC.WO2BEN ).

Just tried it out, works great!

Giving this a bump since it went dead, is there going to be a production unit offered? All I see listed anywhere now is a p/n 30-0333 is the p/n 30-0334 a special order from AEM and we then still have to bother DrMike for a reflash to drop the serial com so dual WBO2 daisy chain can be used?

Thanks

Just use the analog signal. It's spot on with the digital gauge and quicker then the serial connection anyway.

The AEM guys have been swamped, lately. I think, mostly with the response to their CD-7 display thing. So, they have not had time to test/qualify the new 30-0334 firmware. We kinda threw a monkeywrench into the process by doing the dual-channel thing, after they tested the original EFILive changes. So, they probably don't want to release the single-channel version, then the dual channel version. And just make one part number.

The dual channel firmware passed the bench-test, here. But, needs to be field tested.

I'll see if I can check in on them this week.

The dual channel option is there going to be two gauges needed to run both sensors? Sure would be nice just to have one to cut down on the clutter and still have 2 wideband sensors.

[dr.mike]

Yeah, it would currently require 2 gauges. I can probably set up a 30-0310 to act as the second channel. But they are hard to set up, because they have no UI. It would always need to be 500kbps 11-bit ECU 0x7E6 PID 0x25
At least, that would clean things up a bit.

[dr.mike]

Good news. AEM has finally released the 30-0334 replacement for the 30-0333. This is the equivalent to the most recent re-FLASHed units that I have been doing. They support dual widebands with EFILive. ( which is no small feat ) Unfortunately, it was too late in their process to get them to add the spare pins for the analog/serial interface. :(


Double-check, when ordering from a distributor that you are getting the 334 and, not any 333's they may still be in the pipe. 30-333's work via OBDII, only with brand 'H' scan tools.

This probably deserves it's own thread...

Awesome.

I wonder if i can get the e38/e67 to read and use this data.

[joecar]

dr.mike,

cool thanks.

so you can connect dual -334 wideband controllers to the CAN bus and be able to log both widebands from EFILive;


we need to give this some exposure... I'll make a nice thread (I may need to borrow some pics).



( and I'm going to budget myself to get a pair of these for my own use )
