OK, I'm up and working using the latest version of the API, and updated all the functions successfully, and the Faker DLL works perfectly.
Still not working in the car so far though!!!
The code that I'm using is here
http://www.stevegoodman.plus.com/ECUData.zip , left with all logs after running it (nothing seemed to show up though) - the two batch files are to copy the ELM/Faker to a single DLL so I can switch between them.
Attached is the error message - I couldn't see anything in the log
