A 411 swap is where someone installs a PCM from an ’01 / ’02 model. While it is feasibly possible, it will require you to set down and re-pin the connectors with your existing harness. Tedious for sure, but very possible and makes for an excellent swap. However in the Houston area there are people that can tune a ’96 thru ’98 black-box PCM, for instance Wheatley comes to mind.

but the 96-97 will not allow data logging so like dyno tuneing would be very hard to do because of lack of that ability i am thinking of the 411 swap for that reason .

black box rpm is limited to 5800rpm i think?

0411pcm you can raise it to about whatever you want, datalogging, and overall better pcm, supposed to respond quicker too.
