Title: me7sum noob Post by: nickw on May 08, 2019, 03:09:29 PM hey guys! I've been playing with tuning my 2000 audi s4 that im installing my built 1.8t in, I figure ill use the high mileage engine for a "test and tune" I am a noob with all of the tuning and me7sum stuff. I have taken the original .bin file and I've attempted a soft launch control, rear o2 delete, and I've changed the speed limiter. The issue im having is that when I use CMD in "windows 10" it will run the checksums and correct them so figured it saved them, I then loaded the tune on the car and now its bricked. I went back into CMD and run me7sum again and it said it corrects 5 checksums. I cannot find/figure out where the corrected files are being saved or how to save them. any guidance is appreciated! I've used the search bar here and ive tried google but I cant find a definitive answer. Thanks

One is the input, the other is the output. They are in different directories since you specified me7sum\ in one and nothing in the other. Please do a bit more cmd.exe research :) Title: Re: me7sum noob Post by: nickw on May 08, 2019, 04:15:46 PM ok, thanks for checking out my post. i figured something of that nature was happening, but i wasn't totally sure.
Title: Re: me7sum noob Post by: nickw on May 08, 2019, 05:21:43 PM i feel pretty dumb :D i finally got it, guess ive got some learning to do. thanks for the help without burning me man!
