You’re a better man than I am for even trying to help. I just scratched my head and decided not to respond. ---

He probably wants a different **ECU,** on the theory that it will be “better” than the stock unit. “Better” in what sense is debatable but probably faster acceleration or some such. ---

I get that he is looking for a different ECU but for what? His current engine? A swap? A tune-able ECU? He says he is going to “building the engine” but it isn’t clear if it is the H22A or another. ---

The Hondata s300 / P72 ECU package was the crowd favorite back in the day. I have no idea if that company is still around. If not, you’d have to troll Honda tuner sites to see if anyone’s parting one out. You’ll need a laptop to program it. We didn’t have smart phones back then so there aren’t any methods to control it with an app. ---

I don’t exactly understand what OP intends to do, but I do indeed like those early 90’s Preludes. Very nice looking cars. If OP can get it running well, looking showroom new, what a sweet ride. I think there’s a magazine titled “Honda tuner”, the advertisers there might be a place to ask if no help found elsewhere.
