since i shut my TCS off a few days ago the very annoying (and infrequent) lags (sort of like a prolonged turbo lag) SEEM to have stopped.
i have rear tires that look a little like slicks, i think they spin more than normal tires and were triggering the TCS. or maybe it is the tire pressure or the rim size
It is quite possible that your TCS is being activated because of your worn rear tires, particularly if you are using tire sizes that are not the best sizes for the NSX's TCS. For proper operation, the TCS is calibrated for the ratio of the stock rear outer tire diameter to the stock front outer tire diameter. Theoretically the threshold for proper operation is that the ratio of the outer diameters must be within 5 percent of stock. However, there are variables that affect this ratio in addition to the nominal tire sizes (as labeled on the sidewalls), plus this threshold is not precise (it's not like it works perfectly at 4.9 percent and never works at 5.1 percent). One of these additional variables is indeed the amount of wear on the tire. That's because a tire that is very worn has an outer diameter that is around 2 percent smaller than a brand new tire, due to having less tread depth. So maybe your tire sizes work okay when tires at both ends have the same amount of tread depth, but not when the rears are worn and the fronts aren't. Differences in size, front vs rear, can also result when mixing different makes/models of tires, front vs rears, because some tires can run large while others run small, even when labeled with the same tire size.
However, I'm guessing that you are not using one of the combinations of tire sizes that work best with the TCS, and that your TCS problems will go away when you start using one of these combinations:
205/50-15 front, 225/50-16 rear
205/45-16 or 215/45-16 front, 245/40-17 or 255/40-17 rear
215/40-17 front, 265/35-18 rear ('91-93 NSX) or 255/35-18 rear ('95-05 NSX)
215/35-18 front, 275/30-19 rear ('91-93 NSX) or 265/30-19 rear ('95-05 NSX)
I have never seen an NSX have problems with the TCS when using any of these combinations of tire sizes, with the same make/model for all four tires. And 90+ percent of TCS problems I've seen have been due to using combinations of tire sizes other than those listed above (although there are some other size combinations that work also).
