I'm almost done compilling the stuff I need for my LS/Vtec swap, so a new ECU is next on the list. It's going into my 89 civ 4door. My question...what would be my best bet for an ECU? I'm thinking a P72, but what year GSR should I be getting it out of? Also, can I surpass getting a new ECU altogether and get the stock LS chipped? Any help would be much appreciated.

 

I'm assuming youre running nonobd (89 civic), for that you only have 2 options, pwo or pr3....
