Easiest way of correcting Checksum on ME7.1

[J_amb_o]

My ECU is 8D0 907 551 C

I have found maps in TunerPro, but before I can burn, what's the easiest way to correct the checksums?

You need to correct with checksum software... POST your file and I will correct for you

Hi,

posting the file is no good, as I am tuning the car and will need it correcting many times, so I need a way of doing it myself. What software can I use?

You need to purchase the checksum software from EVC... 1000+ euros ... If you have msn you can send me the file each time and I will correct for ya

Send me PM

I have WinOLS, that looks like it may do it, it asks me if i want to correct the checksum when I adjust a map. But then when I goto the next map and change something, it doesn't ask me. Not sure if it's doing it automatically.

in WinOLS window at down you have symbol "Σ" , it's for Checksum ,
if Σ is green checksum is corrected so it's OK..
if Σ is red checksum isn't corrected , so don't OK..
