it actually bemuses the hell out of me how a potential R8 owner would be driving a Seat at the mo anyway but hey ho life is full of surprises!!! tis certainly one impressive form of upgrade so go for it if you can I'd say.
Well i think if you've done all the h/w chekcs you can think of that can cause the flat spot, and there's nowt left but the s/w, then logic would say try some different s/w then!
seems logical to me. If its causing u that much of an issue that u need to air it everyday, then rather than getting annoyed over i'd resolve it. eg change cars, change maps, revert it to its previous state when it didn't have a prob, whatever. If something doesn't do what I want it to do to a satisfactory level, I'd simply get something else that hopefully does.
Actually I'm not defending Revo at all. Revo can defend themselves. They've already stated their position - its not S/W related.
Maybe you need to do something along the lines of what JKM did for Illyun, which was to disect his engine checking loads of bits. There's a long old thread on here about it somewhere.
