Extinct, looks like you're making good progress. Paul has kindly posted pretty much everything you need to translate the ADX into an EFILive xml file. If you want to post the xml file you have so far I'll have a look over the weekend, it makes it a bit hard to test without a controller to test it on.

P.S. I am a mechanical engineer too, this stuff is a little different but it once you understand it its not so bad. You'll find once you understand Efilive v4 it was years ahead of anything out there for ALDL, it still is the most stable effective datalogging tool for that comm protocol.

Therefore I am hoping to build a definition file and use my old EFILive blackbox with the external inputs to do input the 02 sensor reading.
dont know what interface you are referring to there but as far as i know EFILive v4 only works with traditional ALDL cables. That is untill Paul get a chance to integrated it with v8 ;-)
