The D15Z1 came in the 92-95 Civic VX.
The D16Z6 came in the 92-95 Civic EX/Si

JDM D15B has the same head as the D16Z6
D15B found in a 1995–1998 Honda Civic Ferio Vi

So if he says VTEC-E is basically the same as out as D15Z1, the ECU used for D15Z1 is.... P07 : 92-95 OBD-1 Civic VX

But I saw this on Hondata...
P08 : 92-95 OBD-1 Civic D15 JDM


So instead of a P28, I need a P08????

 

RonJ I didn't see your posting til just now right after I posted mine. I didn't refresh my browser.

 

P08 actually would be for a JDM D15B SOHC VTEC which is actually more similiar to a USDM D16Z6. The JDM equivalent of the VX engine D15Z1 SOHC VTEC-E would use a P07. Take some shots of your engine including block stamp. It's very possible you have a 3 stage VTEC engine in which case you'll need a totally different ECU.

 

HPH is correct. My mistake.

OP - Post a picture of the engine head code to distinguish the OBD1 versus OBD2 JDM D15B VTEC.

RonJ, you're referring to the number on the block, under the D15B, correct?

 

On the head - Click the links.

 

 

Okay. You have the OBD1 JDM D15B VTEC-E engine, which requires a P07 ECU, as mentioned by HPH.

Can you also post a picture of the VTEC solenoid(s)?

 

 

Post picture looking down at the circled area.

 

 

???

 

Needs new cam sensor.

Cam sensor located inside differential of transmission.


Sounds like you need a new transmission.

Change O2 sensor at the same time to be safe.

 

dude wtf....

 

New cam sensor?? Huh?

 

What's that guy talking about, new cam sensor?

 

Are the P07 ECUs different if your car is automatic or manual?

 

you won't be ablel to use the auto with a 5spd, or vise versa. locate a 5spd P07. They are rare.

 

5 speed P07 are quite abundant, the auto ones are rare as they didn't make them over here. Honestly though you are going to have to do some additional wiring as the P07 uses a 5 wire 02 and EGR equipment that you'll need to pick up. Not sure if it's possible but see if you find a chipped P28 with a P07 basemap.

 

Oh yeah thats right, there never was an auto p07 vtec-e in the states. IF he were to locate an auto P07 would he be able to convert it to a manual are are those soldering points different from a p28?

 

Don't listen to that guy, he's an idiot. Your transfer case is bad.

 

I found a p28 out of an automatic because my car is an automatic but it's not chipped.how do I chip it and put a p07 baseman in it

 

I've been looking all day on Google for the correct ECU for my motor.
I have a JDM D15B in my AUTOMATIC 93 Honda Civic
It's the OBD1 JDM (dip stick in the middle of the exhaust manifold, this is how i know it's OBD1)

What is the correct ecu for this motor!

 

Specify which of the OBD1 JDM D15B engines you have. Block and head codes should help to clear up the confusion.

Place simple questions right into your thread title. Edited.

 

These numbers were on the block
d15b
2232866

This number was on the head
P07-1






I was also reading that this motor comes in 1991-1999 Honda Civic VTi EG4
