AFAIK there was also a change in MY94 to reflect the changed "baseline" wheel size (16/17). TCS triggers when a front/rear rotation ratio outside +/- 5% of OE
Definitely changed in MY97 (C32 motor), and if I recall correctly there were some fixes made in MY98 (problem with drive-by-wire on MY97 ?).
Just curious - why do you want to change it?
Wow! This topic was over four years old! I wonder if that's an NSXprime record for reviving an old topic?
