Hi friends,

I want to change my k-value in cluster because I drive big offroadwheels on it. So speedometer is not correct.

I found in a other forum the addresses of k-value and tire-circumference.

Now the big deal is the checksum. Can anybody help how to calculate it? Or can I use the empty zones in the end of file to made correct checksum over the hole file?

Cheers

paul

Does DashDumpEdit support this binary?  If so, it will correct the checksum if you select to calibrate the speedometer (use 100 instead of the default 105 if you don't want to change the speedo scaling).
