tryin to upload custom tune, but displays: Backup not saved (-11) followed by No tune done due to backup (4). i thought i saw a fix for this but cant seem to find in my searching.
car was bought used with 158k miles and only a corsa cat-back installed by prev owner. never felt like there was a custom tune installed being that it ran stock time in 1/4... but tuner seems to believe otherwise? im not sure what else to do? lookin to try whatever suggestions before tryin to get a refund on "faulty" unit...
