Codes issues - Cat6 Tune install

[CORHinO]

Battery cables must come off before installing cat6 , then the battery cable to main battery is installed first then smaller battery cable is second before you setup app and turn on truck. if you do it in the right order there are no problems , you can also check the TSB's on the truck to see if there are any issues make sure you update cat6 after installing it. also make sure parking brake is off before driving it can cause issues.

Thanks for this post. After installation it threw a P068A code with a CEL. Then disconnected negative battery cables, OBD II, and the throttle/pedal cable. Reinstalled pedal cable, OBD, and then reconnected as you said, main battery first then auxiliary. No codes now and works great.

Removing the MAP sensor took the longest, dang time...unscrewing that bracket helps a wee bit, but there are so many cables and attachments on top, it's a bear. Luckily, similar to @RamFan , I have long fingers...

It did throw the common CEL code; cleared it and it's been perfect ever since. And OH MY WORD...does she drive wayyyy different; had it on Level 2 and threw into Sport mode - my word, she quick. Someday, Level 3 with Sport and do a 60-time.

BTW - loving this forum; lots of great information being shared.
