Hi all,
I hope that this is the the right place for this (sorry if not) - i have bought a 95 hatchback civic the split boot one.... on the log book it states it has a D16Z6 vtec engine in it, but i have checked the engine and it says D15Z3 the VTEC-E engine. when i asked the previous owner he said he go it with that engine in it....... But the problem i have is when i sink my foot and reach that magial RPM it begins to hit what i could descride as a limiter for the vtec to kick in i have to lift off the gas and then accelarate again, i have also tried progressively accelarated to the 5500 rpm and the vtec kicks in fine with a slight hessitation.

Can anyone help me in this situation........ i am not really clued up on the vtec system- i am getting a haynes manual to help me hopefully......(i know haynes is sad but i need to)

Hope u's can help- speak to u all soon

Paul

When whoever put that engine in it, they probably forgot to put in the correct ECU. I talked to a guy before who had blown his engine and swapped in a d15z1, but forgot to swap the ECU and the car did what you are talking about.

D16Z6 uses a P28 ECU. If that's what you have then you have the wrong ECU for the D15Z3.

I think you're supposed to have a P07 ECU. That's what the D15Z1 uses and they're both VTEC-E so it should be right. Are you out of the USA? because that's not a USDM engine, it's from a Vti.

If it's the wrong one and you need to replace it make sure you get an ECU that matches your transmission. The manual ECU is different from the automatic one.

 

yep seems like the car needs a good ECU tune

 

As you guessed im not from the usa, im from scotland, UK.

i have checked the ecu and the on that is in the car is a P28 so im now gonna source a P07 ecu, will keep u's posted on what happens

cheers for the advice
