Dr. Mike,
Are you still offering reflashing of the AEM 30-0300? I just bought an AEM 30-0300 x-series UEGO for my LS1 Trans Am. I am getting ready to install it, then I came across this thread. If this will make my HPTuners read the AFR more accurately, I'm all for it!
is your PCM CAN based ?
Its stock 1999 LS1. Sorry, I don't know the difference.
Sorry. That is too old to be a CAN based PCMUsually, you need to be 2008 or later. So, you will need to use the analog interface. Fortunately, the analog on the 30-0300 is excellent. And has built-in compensation for ground offsets, etc. For now, there is no way to use OBDII to transfer data, with pre-CAN systems. Hopefully, with a future HPTuners update, it will work.
You can also use the serial interface option for pre-2008 setups....will have to buy pins from Digikey (see manual for p/n) and wire to a DB9 connector (Digikey, Radio Shack). Use a Serial to USB converter cable (Amazon, Radio Shack) and transform using Serial options.
I have read (not experieinced) that some earlier (but more like 2006, 2007) platforms may work as well but as Mike said certainly not the LS1a/b configurations.

OK read all this thread, but could someone please give me a bit of advice for my application.
I currently have the AEM 30-0300 and have it installed since over a year ago. I just purchased HP Tuners PRO and want to start doing some data recording. Do I *need* to change to the AEM 30-0334 unit or can I just use the brown/white wires to the HP Tuners Pro unit?
Vehicle is a 2007 Trailblazer SS with E67 ECM.. which apparently communicates CAN over the ECM/TCM but not for the BCM.
The 30-0300 is plenty fast. Use what you have!Originally Posted by epix
I'm in the same situation as above "Vehicle is a 2007 Trailblazer SS with E67 ECM.. which apparently communicates CAN over the ECM/TCM but not for the BCM". I only have the standard Hp Tuners and not the Pro. Can I use the AEM30-0334 and connect my HP Tuners through the AEM pass through OB2 port to read the A/f in HP tuners?
Yes as long as it is really a canbus vehicle.
I really need to gauge how many people would actually be interested in a J1850 ( pre CAN ECU ) interface device for the 30-0300.
What would this interface device do? Pardon my ignorance.. steep learning curve (but I'm trying/researching!)
In a nutshell, it would allow the 30-0300 wideband to communicate to the MPVI directly, via the OBDII interface. Just like the 30-03333/0334 does. But, the 30-0333/0334 only work with vehicles with CAN based ECUs.What would this interface device do? Pardon my ignorance.. steep learning curve (but I'm trying/researching!)
The new interface would be for the older J1850 based ECUs from GM MOPAR and Ford. So, everything from 1996 on.
How much and where do I send moneyand when can I get it. Lol
OK. That makes one.
Make it two
9 sec Montecarlo SS
I'd like this also.OK. That makes one.
me three.
Which applications are you looking for ? GM, Ford, MOPAR ?
GM application
Any chance this device would work with the 30-0310 as well?
