I cleared some space, last night.

Recently, someone sent me a "30-0300" to have its firmware re-flashed, for OBDII ( 30-0334 ) functionality.

It turns out, this is NOT an AEM 30-0300 wideband gauge, at all. It is a poorly made...

I am currently recovering from yet another eye surgery. This one seems to have better results. I hope to be back up and running by the end of the month.

The 30-0305 outputs the same AEMNet data...

Close... I had eye surgeries on both eyes, over the last year ( vitrectomies and cataract lenses ), . I am "mostly recovered". But, it is, still, difficult for me to do programming work. It is...

OK. Sorry again about the extended absence. I had multiple eye surgeries, on both eyes. They are letting me get back to work, now.

Sorry, all. Been dealing with some medical issues. I hope to be back to it, soon.

I cleared some space :)



I was able to grab an PCM from a 4.7L V8 Durango. That should do it, at least for the JTEC stuff.

06 Silverado has a pre-CAN ECU. The 30-0334 only works with CAN based ECUs. Usually, 2007 or later.

It is, mostly the same firmware as the 30-0334. But. it has no user interface/display. So, if you want more than 1 wideband, you need to order them preprogrammed as #1, #2, etc.

Try doing an info log to see what all is in there.

It should show up as "WB EQ Ration 1 (SAE)"
It does not show up in the "X-Series UEGO ( 30-0300 )" section. That is for widebands that are connected via the ProLink.

What is the vehicle ?

If you have the MPVI3, the best way to go is the AEM 30-0300 ( not 30-0334 ) , with the ProLink, via the ProLink CAN interface ( not the OBD2 CAN, which your PCM does not have ).

Looked on eBay. Those look kinda pricey, in case it were to get damaged, in the process.

PM me.

The 30-0300 and 30-0334 use two different protocols.

The 30-0300 uses AEMNet protocol. It can be read by the ProLink CAN inputs. And the data shows up in the AEM section.

The 30-0334 uses...

But, while on the subject of Chrysler products,does anyone know what ECU I can get, that I can get the pinouts for, so that I can run it on my test bench?

My ECU simulators do GM and Ford. But,...

If you have a prolink, you should be able to connect the wideband via CAN.

If you are using the MPVI3, with the ProLink, you can use CAN on any vehicle.
The ProLink CAN interface connects, directly, to the AEMNet CAN lines on the 30-0300/30-0310 wiring harnesses.

In...

Not quite all. There is an ISO-9141 protocol, used, mostly by pre-CAN Japanese vehicles. It is, actually, one of the easiest protocols to cover. I had to drop it, in order to save room on the PCB....

Not with the 30-0334. But, rather, instead of the 30-0334. i.e. it works with the original 30-0300 and/or 30-0310. But, instead of providing an OBD2 interface, only for CAN based vehicles, like the...

For the TL;DR crowd :p

This box is an OBD2 "piggyback" ECU that serves up custom PIDs, as if it were part of the stock vehicle's data bus. It is a pass-thru connector that goes between the...

I can probably send units out on Monday.

OK. These are as ready as they are going to get. Everything is working as designed, on the test bench.

I am looking for the 1st 3 testers. Ideal candidate is someone who:


is using the AEM...

Which Dodge/Chrysler/Plymouth ( and Jeep ? ) applications are people interested in adding support for?
I am going to have to grab a couple of PCMs off of EBAY and Frankenstein them back to life on...
