i am checking the original file and it passes, then when i alter even only  the rev limiter it fails to correct the sums, this is my second car (i have one s3 - and i had no problems for tunning almost everything on her) now i am trying to do it to my brothers car, and i fail checksumming.

Is it bad because of my tune? Or because it didnt download correctly. I tuned my other car  with no problem at all. I really cant figure it out why it is bigger, how to correct file size

In the future please put the PN in the topic. I have changed it for you.

Also post output in plain text not a screen shot so I can copy/paste data from it.

It could be this file is not supported by me7sum. Do you have an ORI i can test with?

Whatever modifications you did were bad. You have a bad map pack or you really screwed something up. Start from stock again, fix each map one by one.

And here's the corrected stage 1...


Ferrari 360 ME7.3 Rom Tool. *BETA TEST Last Built: Nov  6 2019 07:49:40 v1.71
by 360trev.  Needle lookup function borrowed from nyet (Thanks man!) from
the ME7sum tool development (see github).

..Now fixed and working on 64-bit hosts, Linux, Apple and Android devices Wink

Semi-thread jack: have you run into circular or varying csum location dependencies? for ME7Sum I could not find a fixed checksum fixing order which works in all binaries.

Seems to find everything no problems and never any circular references. Check out the code its all on github.

I've got the same problem once with the same file with nls routine
Changed routine offset and counter memory adress with no luck.

Not finding, correcting. I haven't found circular references either, but i haven't found one order that always works.
