I have a 96 civic. Is it a d16 or d15 in there stock? Also if I change out my old motor with a new motor (of the smae type) do I have to get the computer from the new engine or will the old computer work with the new engine?

First off, you have to tell us what trim you have, that's EX, DX, etc. Certain trims came with certain engines. I am pretty sure though not positive that all 96-98 came with D16's, though it's very possible I'm wrong there.

Anways, for your swap, no, if you're changing in the same exact motor then you DO NOT have to change the ECU (computer).

 

Ill check l8r but im pretty sure ur right and it is a d16. So if I go out and get a d16 motor the stock coputer will work. No electrical codes not working in conjunction? Just making sure so I dont waste money on a new engine.

There's more to the motor than just "D16"

If you look to the left of the exhaust manifold/header when looking at the car from the front, down a bit, you'll see the serial number and the engine code engraved into a little plate right above the tranny sorta.

It's probably a D16Y7 (the non-VTEC) or a D16Y8 (the VTEC). Like I said, I don't know that much about 96-98 models where I could tell you all the possibilities it can be. So look to the left of your exhaust manifold, it's right there, in big 1cm high letters - "D16XX" or something of the sort.

If you have a D16Y7 and you put another D16Y7 in there you won't have any problems. If you put a Y8 in there you'll have a bunch of problems as the fuel maps aren't the same, the ECU won't look for VTEC, etc.

Engine code for engine code (being the same) then NO, you do not have to change out the ECU (computer).

The serial number (below the engine code) has no effect on this.

 

cx/dx/lx 96-98 civics are d16y7
unless its an ex then its a d16y8

 

alright thanks guys

 

what has the d15 in it? See the car im getting (the one ive been talking about but dont have yet) is a 96 civic ex but the guy my friend got the car from said it has a dx motor in it. So what would I have to do to put a ex motor back in? Should be able to just drop it in right? Since the ecu already has the vtec hookup. Also with a vtec if you want to upgrade the cams what do u guys suggest and do u have to do anything with the computer to put them in? Thnx again guys. Really appreciate it.

Not sure about ALL the cars that came with that motor, but the 92-95 NON EX Civics came with a non vtec D15 of some sorts. I'd assume the Del Sols of the same trim also.

Im sure someone else can easily list the other models that came with this motor.

 

depends on what year DX it came from, depends on how they went about the swap, for instance, if they used a 92-95 dx swap they converted to obd1 and would require differant directions to convert back to stock, and vise versa.

 

So im guessing that either the people that performed the swap either took the d15 non vtec AND ecu and swapped them in but they also could have left the stock vtec ecu in but used it on the d15. Does this sound right to u guys? Also can someone help me better understand what obd1 means when referring to the the cars ecu. Sry for being such a pain in the *** but im just trying to figure out some of the more common obd and what each of them mean or what engine they go to. Thnx again guys.

 

find out the engine code, then look for the ecu ID#, that will help clear up things ALOT.

 

Ok no prob. Should be able to let u know by tonight.

 

Where exactly would I be able to find the ecu Id#? Should be able to find it on the ecu? Where would the ecu be located?

 

check the ECU sticky at the top of this forum, i could answer your question, but that would be good info for the future, read the whole thread, read all the stickies up top.

 

Good news everyone!!! I finally got to get the info i needed. The engine code is d16y7 which i know came in the dx. The ID number on the ecu i read off the sticker is 37820-p2e-a03900-238811 NT Not sure if nt means anything but figured I throw it in there. Thnx guys and just let me know if that the code that a stock ecu from a 96 civic dx would have on it. Thnx again.

 

I have a 96 civic. Is it a d16 or d15 in there stock? Also if I change out my old motor with a new motor (of the smae type) do I have to get the computer from the new engine or will the old computer work with the new engine?

Pop the hood check the tranny it should either say d16 or d15 on the block. No you donot need to change your ecu. Unless you change from auto to 5spd but in this case you don't.

 

mines a d16y7 and if u use the same engine I dont believe you need to change computers.

 

well you would have to swap the ecu for the one that came in the ex then. the ex has the p2p ecu, yours does not have the vtec hookup. but your car would be obd2, so just get the motor, or head from another obd2 ex (d16y8)

 

I think Im just gonna say hell with it and just put in the motor that matches the computer which is a new d16y7. But im gonna build it b4 I put it in.

 

37820-p2e-a03900-238811 NT so does anyone know if this is the code for a 96 civic dx ecu? Tryin to figure out if this is the stock computer thats in my car.

 

Come on guys I need to know if the code above is the ecu number for a 96 civic dx non vtec opposed to a vtec.

 

YES, it is the stock DX ecu.

 

thanks man appreciate it

 

u cam't really build a single cam.. and if ur aiming for better than stock numbers... get a d16y8. it's with vtec and breathes a lot better. intake manifold, exhaust manifold is a lot better. might as well upgrade since ur swapping out the motor.

 

but I kinda dont wanna expletive with the factory wiring harness and i dont wanna mess up the electronics. If I knew how to do it step by step I would.
