K20Z3 Swap problem

[j_c]

Hi Guys, recentely, I got a 07' Si K20Z3 engine from my friend, and I have swapped into my ride which is 07' FA1 with R18A1.

But finally, I couldn't start the engine, I double checked the wiring and everything looks fine.

Can anyone give me some advice to work it out?

Is it Immobilizer problem? If it is, how can I fix it?

P.S. the engine also come with stock 07' Si ECU

P.S. I heared that the K-PRO doesn't work on 06+ civic, is that true?



Many thanks

Damn I never saw anyone swap a z3 into an fa/fg1...One guy did a type r swap. But yea I don't know man. Do you have a dx/lx/ex? Would be sweet if you had a dx no power anything and no sunroof! make that thing a sleeper after it runs

for more infor:

1. I tried to swap back stock FA1 ECU to my ride, I could start the engine

2. I used HDS to check the system and try to flash the key with SI ECU, but HDS appears:

a. immobilizer not normal code D3
b. no communication between ECM/PCM and immobilizer unit

Man, I have no chice, because the FA1 is the only model we can buy in our country.

This happened to a friend when he did a type s swap, he took it to honda and they matched the key 2 the ecu, they did request proof that it was not a stolen engine

I'm guessing your a tech since you have a HDS? If your using the correct hds password on request it should let you override any key I would say enter All Keys Lost and reprogram any keys you have available the ecu will learn that key try that with s.I. Ecu goodluck

hopeful you don't need a s.I. Harness which I'm thinking might very well be the case there's no way in hell you can run an si motor on a single cam ecu harness and motor harness .... GL

you ran the K20Z3 on an R18 ecu? how did it run? just curious.
BTW, you definatly have immobilizer issues. if your car ran with teh origianl ECU and not with the K20 ecu, its a communitcation error. make sure that the keys are coded correctly, and the immobilizer and ECU are communicating with the correct codes. if you could reprogrma all of them, chances are your car will run fine.

Thanks for your responding, man.

My SI ECU also come with SI harness, just it seems that HDS can not communicate with SI ECU...

I have sent my ride to local honda dealer store, but they can not help me out, either!

I just can started the engine with R18 ecu, but I never try to drive....

My K20Z3 does come with SI ECU, but my HDS can not communicate with SI ECU when I want to flashing the key....

The key codes are stored in the top line of the reprogramming for the ECU. Just get the keys coded to the car and it will be fine. PM BLueroadster he has done the rekeying process numerous times before.

There is a hondatech on here lemme find his name.

[JeShUa]

You need to program the key for the Si ECU.

[Highrev1]

PM udumkid, he has been sucessful with swapping key codes to different cars and can give help to the dealer techs..

* I Have Finally Done It!!*

Thanks man

[emancivic]

good luck pm'd

[byronl225]

just a quick question, was the z3 motor a straight drop in for the fa1 chassis?
