JDM D15B Ecu swap prob

[vtecjdm]

Got a Jdm ek civic 1996 with 1.5 vtec d15b and obd2 ecu .. now i`ve got a couple of probs with the ecu .. so i decided to make a swap to an obd1 ecu.

Now, if i get a conversion harness so i can connect an obd1 ecu ..what ecu do i need exactly for my engine ... mine`s a P2J ...

I wanna convert to obd1 so i can connect datalogging stuff since the obd1 ecu seems easier to mod.

Any help much appreciated.
Thanks
