swap ecu help

Ok, i'm either getting the d15b vtec or d16z6 engine for my rex next month. Im keeping my auto tranny for now. What ecu can I get that will work on either engine with my auto box? I have an 89 integra auto ecu sitting around can I use that with the apexi V-afc unit?


Thanks guys... just wanna buy the right shit the first time from now on.

yeah that should get the job done... but man those auto boxes are dogs...

I would just get an auto EX ECU.
