Assuming the steering feel on a 2010 TSX is "better" than that on the 2009 model, does anyone have any ideas as to whether it would be possible to upgrade the steering on a 2009 model?

Not sure if such a thing is possible, and if it is, what would be required ... e.g. software update only? New parts?

Possible yes, but 2010 is the same and that tells me that Acura does not think it's an issue.

I'm with you I would like more on center feel and a bit heavier , Acura do a software re-flash for the TSX steering! The over 45 year old demographic with still buy it and not know the difference but the younger car guys will love you.
