i got my new motor in and running but i have it running on a P28 that i had chipped for my 550cc injectors(Y8 motor the ecu was from). can i run a V-tec ecu on a no v-tec motor? what will happen? or is it fine the way it is. i kno the right ecu is a P06 for the Y7.

no....it wont run right because the iacv pin locations are different and the vtec ecu will be looking for a 2 wire iacv where the non-vtec motor is running a 3-wire iacv. have you tried driving it yet? im kindof in the same boat as you. w/ the vtec ecu in there it is stuck in safe mode and wont go above 4000rpms, and mine is an auto trans and the ecu cant figure out what to do w/ the trans. w/ my non-vtec ecu in there i can retain my transmission driveability, but since i already wired everything up for vtec and changed my iacv wiring to accept a 2 wire iacv i have the lovely bouncing idle thing going on and throttle response is pretty much null. i know i shouldnt be driving it like this, but i dont have a choice. any other questions, or anybody want to correct me....please do cuz im in a bit of a pickle myself

I ran a P28 on my y7 just fine. It was a 5spd ECU/motor, so I didnt have any IACV problems. But, a Vtec ECU will run a non-Vtec motor just fine. Just might have a few of those annoying issues.

550 cc injectors? dude do you have a turbo or something?? im always hear that the honda engines runs better without a lot of gas, i live in Venezuela and i pay 2 $ for a full tank, the gas is really cheap here but i'd never think about change the injectors to a bigger ones, maeby to a 215 cc from a Y8, (i have a stock Y7)
