Tuner pro checksum help.

[Steve Webb]

Hi guys,

I got an email asking for some help with a checksum calculation for an XDF tuner pro file last night.
Any of you lot got experience with this sort of thing?

Hi Steve, well, when you make changes with tuner pro or other software, checksum is changed... i think that it doesn't matter if checksum is different. i tuned my Q4 by myself with tuner pro and checksum of course now it is different. but if you learn something tell me please, just to know something more. i make a lot of chances with tuner pro. i even change rpms brake points etc

Hi, it was my question, "reposted" here by Steve.

"fortunately" Q4 doesnt have check light on dashboard, so only problems can be with diagnostic tools, i think.
I made remote mapinging for one friend of our Italiancars community. No problem at all.
Only settings of boost was bit lumpy, but its another story
