No longer able to detect through gpt pins i opened ecu soldered boot wire onto pad inside and if i select (53) tc1766 micro 1504kb i can read and write successful but car will not start has lots of faults on the dash.

How to solve?

When you failwrite file you erase 18000-1BFFF area. It's BOSCH service loader area.

You must select 53 module, use write function and select off optimization write, select write all, include, service areas and [Other] option in ECU selection and not correct checksums.

 

You must select raw write. Not MEDC17. And your reading is enought to recover your ecu.

Read your file after crash and check 18000-1BFFF area.

 

53 module of your ktm bench 1.20 clone tool to use to check your file after the crash.

You must read your bad file in BOOT mode. And compare it with your original read.

Good luck!
