Ok just had a read of the EAE part of the 'Manual' and it looks pretty simple really, just small methodical adjustments until you get the response/AFR's you want!
Much much more accurate than Map vs TPS and will provide a much smoother result I would imagine.
Will have a play once my main VE table is finalised as without that beeing 100% it's a waste of time! lol

Have a look here xr2wishy http://www.msextra.com/doc/ms2extra/...anual.html#EAE explains it all really well!
