Hello Rauf

A belated welcome to the forum.

I have been looking through the manual but cuold not find many notes on replacing the ECU.

The instructions basically say that you should check ground before replacing as often the ECU will malfunction if ground connection has deteriorated.

Good luck

ps. Have you opened up the old ECU? I wonder what's inside. If its a microcntroller it would be educational to look at the code.
