for the latest update of this adx the following has been added:
- No More 1 speed and 4 speed as separate versions. you choose the connection macro yourself (defaults to 1x)
- Added Wideband input support for the AVT 852 equipped with ADC
- Added basic DTC gathering support - see http://pcmhacking.net/forums/viewtopic. ... 894#p66894

to get the wideband working, if you have ADC already enabled on your AVT, you can hook it up to channel 1, otherwise you may be able to add the missing components to get it working (which is what I did) details on this are difficult as each revision of AVT had different components missing. watch out for a separate thread detailing this.
Also, you will need to edit the formula for the wideband value to suit your range, currently it is set to: (((22.39-7.35)/255)*X)+7.35 im sure you can figure out where to type your range numbers in the equation
this screenshot was taken on my bench PCM, which is why some values look a bit funny.

for the DTC gathering the adx is a bit buggy due to the way tunerpro handles incoming packets. its a bit of a hack to get it working at all. You open your FAULT CODES item list and then execute the fault code macro from the send command toolbar. it can read up to four DTC's at a time. if you do clear codes, you must close and reopen tunerpro before checking codes again otherwise the first codes you read out will become stuck in the DTC2,DTC3 and DTC4 values.

I have also made a completely new ADX that loads up the PIDs into 3x 6 byte DPID's then requests each of the 3 DPID packets in turn. so instead of reading 20 PID packets each cycle it only reads 3 DPID packets. I recently got this adx working in aldldroid on the avt-852 with an android otg cable.
this adx doesnt have as many pids as the old style ADX so I have kept both available.

1.4 update - 6-12-2012 added some new pid's, knock stuff, and IAC motor position 1.2 update - 23-03-2012 found an issue with the coolant temp, packet offset off by one, explains the funny coolant temp readings some have been having. 1.1: I changed the default macro to update all the priority items in between each individual non priority PID and it now logs all of the items shown on the "GM & SAE DASH" it seems to work better that way.
