alright...well...

case 1: yes you can have that ECU in your dohc zc crx and it will work...pull the carpet back and your ecu should have a barcode on it above one of the plugs. If you can find the PM6 then its CRX si, if it says PG7 you have an 88-89 integra, and if it says PM7 you are lucky and got the ZC ecu.

Case 2.

No. DX is DPFI and the SI is Multiport Fuel injection so that wont work. And the automatic transmission and all that ....just no...it will not work

^ an auto ecu will work in a manual; it'll throw a CEL though. I believe you can modify an auto ecu to work with a manual without throwing a CEL.

yeah..i but the DX is dual port fuel injection and the si Is multiport fuel injection.

Im pretty sure you would have to do a MPFI swap for it to work.
