What software would you recommend for calculating and replacing checksum after removing immo from software.
Example : removing immo from renault scenic ecu sirius32 from flash 29f400 (i'd like to completly remove immo.)

Why do you need to calculate checksum.
In Sirius32 you read the file by OBD and write by OBD using a remap machine tool.
No problem to do it.
If you have Beeprog for example you can also remove the flash, read the file, correct the file and program it again.

I use labtool programmer.
The car did't start without fixing chechsum. Also the software for immo removal software (immo u.d.) suggested to recalculate checksum before programming. I had to send file to the tunner I know that fixed it and after that it worked.
So what would be software for that?

It is not a problem. I read this with ordinary programmer (labtool).
Which russian programer works with this sirius?

If you really need to calculate checksum the best and easiest thing to do is:
Read the 29f200 with Labtool, open the file with ECM or WINOLS and correct the checksum.
It is easy and fast to do.
After that you can write the file using Labtool once again.

When correcting checksum do I have to set it to the same as it was before clearing immo or just recalculate to adapt to new file?
