Icon5 i need a ECU for my h22a Auto swap

i cant find a p13 auto Ecu anywhere even on eBay they are all 5speeds BTW the car is a 94 prelude came with h23a1
so can i use a p13 5speed? and yes the car is auto
i think there was a JDM h22 ecu from a accord that was auto idk the number on that or can i convert a p13 M/T to auto?
more like what makes auto and m/t ECUs different?
if someone can help me with this it would be awesome that's all i need to finish my swap

are you aware that h22 auto transmissions are known to fail?

On 5th gen ludes, I'm not sure which car he's doing his swap but 4th gen auto transmissions are pretty damn reliable from my experience. But for the ecu you what gen is the swap? Just call engine importers like HMO and see if they have one, soon I'll be doing a swap for a H22A with an auto LSD tranny, I found a ecu for it on eBay, or just get a tuned ecu

There used to be auto p13's all over ebay but since rarely does anyone buy them I guess people just stopped listing them.

They do, but its for the honda accords that use a separate tcm for transmission control, they used an obd1 chipped p75 and a matching tcm.
