You're checking the wrong bin..
C:\Documents and Settings\ABC\Desktop>me7sum.exe testout.bin trytestout.bin
which writes the corrected file to trytestout.bin, but then you do:
C:\Documents and Settings\ABC\Desktop>me7check.exe testout.bin
The last message printed by me7sum is misleading, I'll fix it in the next release.

Test.bin is the file I am trying to correct checksums on. Tes1.bin is what i commanded the correction to be called.

Looks like ME7Check fails on a win-ols corrected bin (which is identical to the me7sum corrected bin)... possibly a bug in ME7Check? That is bad news :/ I will email sezti... No guarantees he will respond though. In the meantime, the corrected file is most likely safe to run... but i'd hate to ask a noob to play guinea pig w/o understanding the risks... your call, but if you want to roll the dice, carry a spare stock ecu with you  |

Not sure yet, I received a response from setzi and it appears that neither winols nor me7sum can correct that file properly.
No idea why yet.

The file you posted has modified checksum routines. I doubt it is your file. If it is, I'm sure you can figure out how to properly calculate checksums for it I have no intention of fixing ME7Sum to work around tuner modification protections. Please don't waste my time posting files you didn't write yourself :/ 1c1

Hey im not trying to waste your time! Im not trying to do anything sketchy here. This is my original bin when i bought the car. Is it not stock?? All i did was change rev limit and some stupid things like that to get my test.bin. If i want to be able to tune this car should i simply get a stock mbox file??
I have to edit this to be clear: I attached my bin that i read using nefmoto. I didnt mean to come off as a dick. I just want you to know im not here to waste your time unless helping a noob is then im sorry for that. I am just trying to learn how to tune my car. If this file is not stock please let me know because i am unaware. I will start fresh with a mbox file. Once again i really appreciate your help, I am not trying to use someone elses stuff or anything like that. If this bin is not stock, really i dont suggest anyone using it cause i have no idea where it came from. Thanks nyet for your help, I will just start with fresh file when i can get my ecu boot mode bench flashed.

You must have accidentally modified a few locations you were unaware of. It looked like a tuner hack, because one of them (coincidentally) happened to be in the CRC table.
The other odd change was the first two bytes of the file were zero.

You tell me. Why did you modify the first two bytes of the file? |

Honestly i dont know how to do that. nor what that really means. I tried your program on a .bin online made similar changes and it works. So i think my ecu had something weird on it or done to it.
