hello; I was just looking at a article from a 1990 GS club flyer. It says the GNX and GN has different IC. No big news but news to me is that the same IC on the X is used on TTA. p/n 12396761 and it says it's a bolt in? I know it's an old article and IC are probably better now but I found it interesting if true.
