Newbie, AEM 30-0333 X-Series Wideband or 30-0300 or other

[Inspiro]

Hi all
Newbie to the whole tuning thing
Will be doing a Camaro SS(2012) n/a with HP pro, just need to decide on the wideband to go with it
Unlikely to use leaded(apparently NTK sensor is better with leaded or metahnol),
hopefully I will use the wideband on other projects in the future

As far as I understand, the only difference between the AEM 30-0333 X-Series Wideband and the 30-0300 is the OBD; which has the 2 CAN wires

• What is the use for these CAN wires(I understand what is CAN)?
• Can I use it the wideband while this OBD connector is unplugged( I guess yes)?
• Apparently the 30-0300 comes with the harness that includes the 5v signals while the 30-0333 doesn't, which makes the 30-0300 the better option to be used with the HPtuners pro?!
  or does the X-gauge now put the data on the CAN and the HPtuners get it from there? I inderstand that speed of the HS GM LAN is 500kbps, but does the HPtuner get it at the same speed or there is delay that kills all the pros of the -claimed-quickest responding sensor?

Your help in clarification is highly appreciated

The best combination seems to be the 30-0333 with the extra pins added to the harness for 0-5v and serial data. The pins cost less than $1 + shipping.

Either gauge will work without the ODBII connected. It only needs +12v and ground.

The 30-0300 CAN data format matches their AQ-1 data logger. So, the MPVI does not read it. The 30-0333 is an OBDII ECU simulator. So, HPTuners can read it directly.

The 0-5v output on the 30-03xx gauges is actually VERY good. Either the 0-5v or the OBDII connection will keep the data properly correlated with the other data on the MPVI.
The serial data is another story. It is pretty slow ( 10Hz ) and only 3-digits ( "xx.x" ). I don't recommend using it unless you have to.

As far as speed, either gauge is capable of higher speeds than the current maximum logging rate for HPTuners. The 0-5v output is the fastest, at 500Hz.

Thanks dr.mike for your reply

So this means if I'm using the AQ-1 DL I need to go with the 30-0300, otherwise both are fine

Can I get these pins from Summit? P/N please if possible,
is the wiring included in the provided harness of the 30-0300 or I need to add an extra harness?

[dr.mike]

Basically, the difference is, there is only 1 CAN bus interface on the gauge.

On the 30-0300, it is used for the AQ-1 formatted data.
On the 30-0333, is it used for OBDII formatted data, readable by HPTuners.

The pins are available from digikey. I don't think summit has them. http://www.digikey.com/product-detai...8-1-ND/1989509

The 30-0300 has all of the wires in the harness. The 30-0333 only has power and the OBDII connector in the harness. Hence, the need for the pins.

Unless you are going to use the AQ-1, the best combination seems to be the 30-0333 with thge extra pins, if needed.

Thanks for the clarification

I've logged the 30-0333 CAN output and the 0-5V analog output side by side and have to agree they were amazingly close (and fast). The analog was slightly behind but I'm talking milliseconds behind, not enough that anyone in their right mind would ever notice.

Well I intended to do the same
hahaha

Found some old pics. For the last one I maxed out the analog out so that's why it looks like they aren't matching..

If I remember correctly for the first one the whole screen is 1 second... so very very close

Yes, the analog signal maxes out at Lambda 1.22 vs. Lambda 2.00 for the CAN data.

Was the analog channel sampled at the highest sample rate ?

How are you guys wiring up the power supply for the 30-0333?

I just ran it to something in the fuse box with an add a fuse. I just checked random ones until I found one that came on with ignition on
