i was wondering if there is even a point in doing this.. some kid down here told me that what he was running a b18 teggy ECU in his CRX

 

ive used in my D16a6 crx before a D16a1 89 dohc integra computer. i had no problems at all. it just ran the car a little richer and the fuel cutoff was higher. idk if the B18 computer would work tho.

 

You use it if for some reason your PM6 exploded and you absolutely need to get your car running again. The ECU is thinking that you have an extra 200cc's of combustion chamber, and as such is dumping enough fuel to complete combustion in a 1.8L. But if you feel like raining gas into your cylinders, by all mean go ahead.
