W. Salam Murtaza sb,
If you follow the same thread, you will see my solution to the problem. My elder brother made clone ICs for me, and they are working as expected to this day. The schematics is shared as well, so anyone with electronics experience can make.
You can get the ECU repaired, and tell to replace the marked ICs with ones from another scraped ECU. Or alternatively, buy replacement ECU from used parts market of your city.
