About to order a wb... any hope for us vpw protocol (411 pcm ) on the 0333? O
I would order the 0333 and also get the pins to add wires to the analog output. Use that for now and you have the CAN option later once they get the multi protocol thing going. Just my opinion.
I'm assuming they will eventually get it working but can't promise that obviously...
Anyone tested two/three/four 30-0333 devices simultaneously on the same bus?
This unit has serial and analog outs as well, though you have to add the pins to the connector in order to use them. The way it comes only CAN and power wires are installed. I don't know if the serial output works with HPT, but obviously the analog will.

Yep I should have updated, when I hit repolling it picked up and worked fine with the firmware update. FYI for anyone buying a new one I would save myself the trouble and have the company your buying from call Aem with the serial # off the box they are going to ship you to verify it has the latest update. This would have saved me and James some headache
I've got some screenshots I'll post later of the analog output overlaid with the CAN output. I added pins for the analog output today. Most of the time they're nearly exactly the same (at 2 decimal places they are the same..). Only on very quick/sharp changes can you see any differences. The analog input is ever so slightly delayed from the CAN data and is slightly more "rounded" off on very big/fast changes. I couldn't see it unless I zoomed into around the 2 second view..
They are very similar though

Couple of screenshots. AEM 30-0333 CAN vs. Analog output.
Difference on very fast changes--analog seems rounded off almost.. it doesn't quite make it to the same peak the CAN reading did.

Here's what it looks like in more typical operation.. analog is ever so slightly behind the CAN output. This entire view is 1 second so it isn't much at all. A few milliseconds

The analog output only goes up to about Lambda 1.22 It looks like you might have hit the limit in the 1st pic ?
1.25 lambda on CAN output at that peak
Looks like you're right

Here's another that doesn't hit the limit. Much closer. I am amazed that the analog output is that accurate.

Is the analog sampling rate set to 100hz to match the CAN data?
Other than that, it looks about as good as you can get for analog 0-5v data.
I know that the analog data rate on the WB is 5x faster than the CAN data. So, it shouldn't lag behind. Unless there is some filtering going on, somewhere.
We can't set the rate on the analog inputs, but I believe HPT sets the interface to measure every millisecond, average the data, then report it to Scanner every 10 milliseconds. I could be off slightly on my numbers here.. but I'm pretty sure that's what Keith said. They used to just take a single sample every 10 milliseconds and threw away the other 9 readings. Averaging the 10 readings smoothed analog inputs out quite a bit.
So--that makes since. Very small bit of averaging, but there is a little bit. I may be off by a factor of 10, but the method is the same.

The analog outputs on these new AEM widebands are pretty solid. Allot of it is the ground offset compensation circuit. The DAC channels are also "digitally trimmed" at test/calibration time for scale/offset.... I am amazed that the analog output is that accurate.
There is a bunch of calibration/normalization data stored in the FLASH memory that I have to be careful not to overwrite when re-FLASHing these things.
It almost makes the OBDII output redundant.
Looks like the same thing happened in the comparison traces that DSPORT did in the new issue.1.25 lambda on CAN output at that peak
Looks like you're right
The Haltech and Innovate outputs go to 1.5. But then AEM clipped at 1.22
It just looks funny

I tried them yesterday and they do work as expected
