How can you tell the difference between an auto p28 vs a manual p28? any exterior differences? #'s outside? or what? tried search but it deletes any "p28" and "ecu" from the search words everytime

P28 : 92-95 OBD-1 Civic Si/Ex

EX AUTOMATIC:
37820-P28-A51
37820-P28-L51

EX MANUAL:
37820-P28-A01

Si MANUAL:
37820-P28-A01
37820-P28-L01

This should clear it up.

thanks a lot RareSI... exactly what I was looking for. Didn't want to buy a p28 and it end up being a auto ecu.

unfortunately i bought an auto ecu.

dont mean to jack the thread, but how can i chip it to manual??? how much am i looking at spending?????

I know that a Hondata is able to do it for you. Other than that, Im not sure, good luck.

Well my p28 ecu reads 37820-P28-A52... Is it manual or auto????

I would assume automatic because they have the 5 in the 10's place.
