Hi Guys, Hope someone can help my get my 92 civic to drive correctly.

I have a 92 civic non US, NON-VTEC, cause of the regulations in my country i can't upgrade the engine to a vtec engine...

My Civic had a few problems with the computer and the engine, so the mechanic put in a used NON-VTEC motor (which runs fine except for the idle control is a little wacky) also the automatic transmission seems like its in limp mode because it won't shift after 80 km/h(4,000 rpm) 90 km/h (5,000 rpm). I went to Honda central garage in Israel and they told me that the car has a VTEC ECU, so i have no idea if the issues are related to the ECU, if its an electrical problem or something completely non related.

Can anybody help me figure out this nightmare?

BTW. Honda told me that they can't get me an ECU for my 92 Civic, does anybody know where i can find one?

You have yet to say exactly what engine is in the car. Nor what ECU is actually in the car.

Need to know what ECU you have for sure, if you're running the wrong ECU then we know what is wrong.

Ok we can only help a small bit as your post is very vague.

The wacky idle is most likely the air idle control motor on back of intake manifold. Take off clean with brake clean.

The trans in limp mod, i have no idea has you did not provide any good info on issues other than wont shift.

Ecu-- search junk yards, here on HT (honda marketplace), among other honda forums. You will find one.

Out of not trying to sound stupid, but being a complete newb to honda's the engine is 1.6 L, D16Z9, DOHC I4,

The issue is as follows: Car is idling at about 1000 rpm, start driving in [D] on road from stand still, first shift good second shift good (now i am about 60 km/h, rpm around 3,000), from this point forward transmission no longer shifts the rpm's climb as speed increases (its as if the car is stuck in second or third gear. As an example in my Chevy after i get to about 80-100 km/h if i am not on the throttle the transmission kicks down to a lower rpm, in the honda it just stays at the higher RPM no matter what i do, my fear is if i keep driving at 90km/h over an extended amount of time i will eventually blow up the engine.

so the issue is with ECU from what i understand, because the ECU in my civic right now is for a vtec engine, prior to the mechanic switching out the ECU, it had the proper D16Z9 ECU and the transmission was still doing this, hope this gives more info on the trouble i have

Again. What ECU?
And this
D16Z9
Found in:
1994–1995 Civic Coupé (EJ1) 1.6i ESi European
1994–1995 Civic Sedan (EH5) 1.6i EX US

Displacement: see D16 Series Engines
Compression: 9.3:1

So if this is correct your engine is VTEC.

I believe the engine is a D16A8, according to wikipedia,

all i know according to the registration is that its a 1992 honda civic DL 4 door sedan, and i am assuming the car came from europe as i am located in the middle east(Israel)

Make up your mind. Which one is it? Maybe actually look at it and not worry about VINs, registrations and what Wikipedia is telling you? Check the stamp on the engine block.

My next bit of advice is that the next time someone works on your car, make a note of what was done and what was put into it.

And you have yet to tell us which ECU is in it. Look at that too. If you are unsure then post a pic of it.

Thanks, Thats what i just did, the engine is a D16A7 (stamp on the engine block):

Is that the ECU in your car?

n1motorsports

that is the one that is supposed to be, but the shop put in a VTEC ecu. does it make sense that a wrong ecu will screw up not only the gear shifts but also the idles control of the engine?

grumblemarc

No it doesn't make sense.
Did you LOOK at the ECU?

n1motorsports

no, but what am i looking for and where do i find it?

Former User

The ECU is located behind the front passenger kick panel. The type of ECU will be printed on a label(s).




But it sounds like your auto trans may be bad or the shift linkage needs to be adjusted. Any CEL codes?

So i went and got a NON Vtec ECU; model number 37820-P1E-900... Apparently for a 1992 Honda CIVIC DX 4door Sedan, the proper ECU needs to be: 37820-P27-B50

Once i get a hold of this thing i should hopefully be able find out what else is wrong, i am hoping that the issues is just that, hopefully i will know more info in a few days once i get the ECU and install it. I will update this thread once i have some more updates...
