SAE CAN ADX for AVT cables

Postby Jayme » Fri May 15, 2015 12:43 pm

Hi all, I finally got around to making my CAN ADX. this one is pretty simple. it has no GM PID's only SAE ones. as its my first CAN ADX, it also used individual PID's rather than DPID's so its a little slower. I get around 33 Hz / 11 PID's is around 3 Frames per sec.

I developed this ADX for Alloytecs. Big thanks to Biggvl who sent me an alloytec bench pcm to use for this kind of thing!
I also added a function to check which SAE PID's are supported by any CAN pcm. simply load up either ADX and send the Check PID's command. look for the results in the 'Supported PID List' and post up a screenshot here.

I have uploaded 2 ADX's for alloytec as my bench PCM used PID 14 and 18 for the 02 sensors but my VZ Adventra alloytec uses 15 and 19 for the O2 sensors! so try both ADX's and see which one works. if you have any issues, just use the check PID's function detailed above and post up a screenshot.

I see no reason you shouldnt be able to use the ADX on the E38 v8 pcm's, so if anyone wants to try one and post up the supported PID's screenshot, ill make a v8 variant.

Current Version:
AVT SAE CAN Alloytec2 v1.02.adx
(45.34 KiB) Downloaded 335 times

this version uses PID's 15 and 19 for the o2 sensors.

1.02 Changes:
added MAP item (but left out of data loop for Alloytec)
Added Wideband PID's 34 and 38
Added Raw Hex output of PID check 21-40
New Dash Layout
Added 2 Monitor Charts

Oooo! nice work!

I *think* the new VE SS has an E38.. Ill need to eyeball it I think in the engine bay once i stops raining.
Im happy to give it a go with the AVT and get a supported PID list up!

The "PIDs supported" didnt work though. Said no for everything, not sure what was wrong there?

yeah its not pedal...... its throttle blade.
also WTF.... Data bus must behave way differently on E38 ... either that or my laptop has a big issue hahaha.


as for the check pids command... maybe the command works differently on E38 or something ... not sure.

can you grab a serial port monitor of pressing the check pids button to see what its returning if anything...
