Ive tried the cable and it works. it connected at a baud rate of 108400 i think it was in dumb mode.

From here how do i extract the imformation from the ecu and save it to the computer?

Also how long does it take to read the info from the ecu. Does it depend on the baud rate?

Load your saved bin in any hex editor - HXD & Tunerpro are what most use, winols demo may make it easier to read without being able to build maps/change data. HXD to just change hex data, Tunerpro to build maps/a def file too.

EDIT - Then start by looking for ESKONF as detailed in the links, you'll prob need a def file/help/post your bin up for the other bits
