I have never had transmission hunting at any speed (lots of 30mph) with either of the ECUs, before or after mapping.
OK mapping gave me much more oomph and better fuel consumption. Well worth doing.
My Indie tells me that the ECU is a common one used in plenty other marques in particular Range Rovers, just a different map, so should be cheapish to replace. As long as you know what map to programme in

Your indie is correct, it's a common ECU and the Bosch EDC16 series are very hard to kill when remapping (unless they've not been sealed properly after they've been opened and you get water inside them). Not like the Delphi ones that appear to pack up for a laugh when writing maps to them! I do remapping for a living but I'll say no more, don't want a telling off for advertising or anything!

I'll put Delphi on it today and see if anything looks out of the ordinary. I wonder if it's a software update issue and cars that have either had the box software updated or left the factory with it aren't effected?
