Hey guys,
My tuner sent me a .COZ file because he said it was easier, faster, less bandwidth, etc than a .CTZ.
Only problem is the program won't recognize it. I have the most updated V8.2.2.258 software and firmware/boot block on my autocal....windows shell extensions wont recognize the file as an efilive file. and when i load it on the autocal it gets error 050b when i try to load it to my car. I asked my tuner but hes always so busy and only does emails so id like to try this tune ASAP. Whats the deal?
Thanks!
