Thx - I shoulda mentioned it's an I6.
I just found this thread after a long wander around (you can't search for ECU , 'cause it's 3 letters
that has a long list of ECU parts. Which I couldn't work out what an ED would be, but that's another story.
Seems they have different part no's for manual and auto? Am I reading it right htat the only difference is something extra for the auto trans?
PS - sorry if I sound extra stupid. I've left my car at my old man's so I can't even check under the hood at the moment...
