	me7sum noob « 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

this is what I get, but if I re-run the file to double check it itll say the same thing saying it corrected 9 errors?

Code:

*** DONE! 9/9 error(s) in me7sum\Audi_S4_2.7T_experimental_stage_1_launch.bin corrected in Audi_S4_2.7T_experimental_stage_1_launch.bin! ***

are you checking me7sum\Audi_S4_2.7T_experimental_stage_1_launch.bin or Audi_S4_2.7T_experimental_stage_1_launch.bin?

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
