when you switched ecus did you make sure your adaptor harness is completely hooked up?
is the ECU bolted back down to help complete ground?
Did you mess with anything else when switching ECUs?

everythin was hooked up , didnt bolt it back in (ill give it a shot in a lil and get back to u) and i only tried to adjust the idle control but that didnt make a diff

oh and if it helps i also tried my budys virgin p28 and it did the same thing as mine

How did you adjust idle control?
I know if it was 92-95 civic you would jump the two port hanging under dash by the ecu.
Then disconnect the IAC, then adj. idle.
After all that you turn the car off.
Pull the backup fuse.
Then hook up the IAC back up and pull the jumper in the data port.
Then place backup fuse back in its slot.
Then start the car back up.
What made you change ecu's anyways what was wrong with using P2P?
Where you getting ready for boost or mager mode or what?

a buddy turned a screw in the throttle body
startin my first boost project got everything i need just got to get it on the car and workin ...want to get the p28 to work first so i can send it out to get chipped
-
Yeah you turn the idle screw but before you do that you have to disconnect the IAC.
Look at you manuel for 96-+ civics and see if you have to jump anything and follow the manuel for idle adj.
-
Chip the ECU and there's a Y8 basemap floating around, see if that helps. Some shit about the timing on Y8's.
-
The OBD1 ECU retarding your timing 9 degrees probably has something to do with it.

Would chipping the ecu take care of that thru tuning, or is there a way to still use a stock P28

That minimum base timing shit again?

No, using a timing light to set your timing would. Make sure your basemaps has idle timing of 12 degrees, because that's what your crank pulley is set to, otherwise use your noggin and figure out what direction the 4 degree offset is when using a stock P28.
