I got this ECU with bad checksum,Car had faulty codes for checksum and throttle , and it was running very bad.

Car is far a way and want to make sure rest of the software is good.
I attach file .

it is BMW 525 I
ECU info :
5WK93017

Anyone??????

I think there might be 2 reasons for that to hapen:
1. The 29F400 flash of the ECU is broken (had similar problems very recently with BMW)
2. Someone flashed the ECU with wrong software dump.
There are MS45 and MS45.1 which have different softwares. If you flash MS45 with MS45.1 software the car will throw DTCs about checksums - this happened to me. I see that you read the whole flash already on bench, so now you have to reflash it with newer version ACCORDING to the ECU SW AND HW numbers.
You can just post a picture of the ECU label and i will give you the right flash for it.

Regards.
