i have a 93 honda civic EX 4 door automatic. and i had a new engine put into it, but they put in a 1.5L instead of the original 1.6L. anyways i was looking at new ECU's and i understand i have to get an automatic one, but dont know about the rest of the numbers on it. so i was wondering if you could tell me if either of these would work for my car, 37820-P06-A52 or 37820-P06-A50?
-thanks in advance for the help!

 

p06 as long as you know its automatic...... i have one in my for sale thread cheap..
works great
