i got a 96 d16y8 and i got a p28 ecu and i was woundering if this is the right ecu and wireharness for my motor and for some reason my vtech isnt working

if its going into an obd2a civic then yes

hondaboynky

d16y8 harness is obd2 and the p28 is obd1 so you will need a jumper harness

o yeah thanx for the correction i forgot about that

Yes and no. The P28 should make it run fine; however the proper ECU for your car would be a P2P. Your car is OBD2a and the P28 is an OBD1 ECU. Thw wiring harness should be the one that the car came with, I highly doubt someone would have changed it.

the motor is in a 94 hatch.. so is that one reason my vtech isnt working as well

itsnotfast

If done right, it should work.

madsci

so with my p28 ecu and the wireharness my vtech should work and is everything i have the right set up?

itsnotfast

It should work if everything is done correctly to accomidate the P28. Is or was your car or the donor car automatic? Do you have any CELs?

i bought this car off of my buddy and it was never an auto his dad owned the car from new and gave it to him and i bought it off of him so what exactly do i have to do to make everything work properly because im building the motor for racing and nitrous

Keep the P28 then and build it. First you need to diagnose the VTEC issue. At what point did it stop working. Has it ever worked in that car with that motor? Is the car even wired for VTEC? What motor came out of it?

madsci

umm well ive driving alot of vtech motors and my buddy has the same motor and exhaust system and u can hear the vtech kick on and i cant with mine and i got a wire runnin down fom the vtech silinod to the ecu and that motor came with the car but i had to replace the bottom end with the y7 bottom end because at the time i could afford the rebuild the bottom end
