Sailorbob,
Yep you are quite correct, I found the sidesaddle after the above post, so if all else fails then that's what I'll have to get.............however................
I've seen a nice little board that plugs into J3 like a chip and can be used for reading and writing the ROM, MSD uses one, but I don't know who sells this. A ribbon cable just comes from this to the laptop, or an emulator, which I might get later on for live mapping.
Do you know where I can get this little J3 Interface ?
Also do you know where I can get the cal files for ATAFF and ABARO ?? .............
A specialist has kindly agreed to read my spare ECU's firmware but he doesn't have the cal files, which are, (correct me if I'm wrong), the files that make the firmware intelligeable to a dummy like me
Cheers for your help and advice on all this, feel free to pm me if you wish, or if you can impart any knowledge to my ageing grey matter via phone I'll let you have my number.
Here's a few pix of ma Beastie

Cheers for now,
Dave
