Hi!

I would be grateful if anyone could help me out here.

Car VIN Code: KMHCM41ALAU462066

I have to change my ECU (please see attached picture for reference)

I have contacted a few ECU repair services and got a few hints on what i should be looking for in other model references which will work for me (they will opt Immobilizer out).

So the references for the ECU are as follows:
Kefico maker Part Number: M7.9.8
ECU Ref 3913226BJ0
Software needed: 9001040241KB GMC-AR4DES0-5000

As I was said, the bold parts of the references are the most important.

Anyone here who could advise me properly please.

For what i know, if you can't reflash the immobilizer code (probably in hyundai can do it), u must buy with the ecu the related smartra module and the keys of the donor car (with related steering and door key locks), otherwise the key will not recognized and you can't start the car. I don't know if is necessary to replace also the body computer ecu, but probably not.
The smartra module is a little cube box under the steering rod. For example, in this photo of an ecu of Hyundai getz with G4EE engine, is the box on the left of the engine ecu:


Even if the ecu is different in this photo, the immobilier system is ever the same in the car with G4EE/G4ED engines

These are the specificiations of the system:

but still can't use it because it's not M7.9.8 plug.

Tried searching for the ECU on the web but still no good result.

Even looked for plug and play ECU but bad luck till now.
