D16y5 swap and having issues

Okay so as much info as I can give
Body is a 98 civic lx
Engine was a d16y8
Head was a d15b7
4-2-1 headers
P2p ecu
All motor
So I swapped in a d16y5 vtec-e which is my first time messing with a vtec motor, wired it all up and it purrs like a kitten. Only issue is it won't rev up. Just boggs and falls flat on its face. Put a new distributor, plugs, wires, injectors and reset the ecu without any change....anyone had this issue with a motor swap? any help would be greatly appreciated.

The p2p is the ecu for the other motor, right? If it is, you need the correct ecu.

Probably still running on 12v and ecu is delivering fuel for 16v. Get an ecu chipped for the y5 minus the lean burn mode.

Or buy the right ecu.....

You have to yell VTAKKKKKK for it to work correctly

Had my buddy come over and properly time it and he brought a p2n ecu and after 2 hours of tinkering, she is running right again.

Hell i'd daily the teg and fix the civic up. Keep at it.

Actually I'm thinking about letting the teg go, dailying the civic, and looking for a gsr
