I am converting my 89dx to mpfi and adding a y8 head. I am trying to figure out if it is really worth it to put on z6 obd1 setup instead of 90si stuff and a v-afc for
v-tec. I am only using z6 setup cause i found a good deal on it.

 

How about a little advive on obd0 vs obd1. The search does not give real good info on this subject.
