What is the ECU code for a 1993 Honda Accord EX Automatic?

I've been searching forever and can't find it in the FAQ.

Like how EF si ECU's are pm6, etc I want to know the ECU code so I can search for a replacement

 

dont think autos vs manual are different, but for the EX, it is PT6 i believe.

replacement = JY

 

Okay thanks. No changes from 92-93 correct? I've only found 92 auto PT6 ECU's but they're both 4th gens so I'm assuming it's the same

 

One is
37820-PT6-L52
the other is
37820-PT6-L51

does it make a difference?
