Just need a little advice I'm sure there's a post on here for the same question but I have a 1992 Honda civic hatchback VX model it has a d15b and I think I have a p07 ecu and reading online I need a p08 ecu its single vtec online one solenoid is there so I'm not sure if.I have a vtec e motor in it so any advice is appreciated oh the head on my motor does not say vtec thanks again

Sorry use to other forums not this one

 

You need a p28 ecu which is the vtec one to work perfectly.

However you can use a p06 one if you chip and tune it. Anything else will NOT work

 

EDIT: didn't even see that it doesn't read VTEC my bad dude!!!

 

Yea the head doesn't say vtec but I see the solenoid so yea idk its weird what can u do to get more power since it is a true d15b cuz I've been looking it up and all will cams do anything for me or is it just a waste of time and money?

 

Sorry for the double posts I think i have a p28 I'm going to check today and should i be able to hear my vtec crossover because I don't so what can I do to know if vtec is going into effect ill post pics also of the head engine stamp and the solenoid

 

1992 and 1993 D series VTEC engines don't read VTEC on the valve cover.

If it is a true D15B JDM Vtec engine, then the ideal ECU would be a P08 or a chipped P28 with the correct basemap for the D15B.

The P07 is the original ECU for the VX engine.

 

Ok well where the cam is it looks like a jdm one with ngk on it and Japanese writing the motor was swapped before I got the car and the stamp only says d15b I'm going to get pics of everything after work so it may help yall

 

D15Z1 is not V-tec as we know it. It only changes from a 12 Valve mode to a 16 Valve mode. NO V-tec ecu(P28/P08/p2p) will run it, ONLY the P07 can run the D15Z1......BUT one guy on here posted a thread on how to change the D15Z1,P07 head into a D16Z6/P08 head.

 

Ok but I have the vtec solenoid and all and the stamp only says d15b that's it

 

Ok so i have a p07 so all I need to do is swap that with a p08 and it should be good Togo right?

 

Yes if you swap to a P08 ECU, which is the JDM ECU for the JDM D15B then it should work fine. Or like others stated, you can use the P28 ECU. I think you would have better luck finding a P28 ECU. I have a D15B and I'm running it on a P28.

 

Ok thanks for the help

 

wont run the engine or the lean-burn the z1 is famous for? Cuz im running a d15z1 with a p28 as we speak runs hella good to! just had to wire in the 4 wire o2 sensor cuz that wide band o2 is to expensive.
