I tried to use the Quick Cal unit with no success, will not write to the 2018 2500 gas trucks. RC said has something to do with the 18 Rams auto tune software. Question is can the dealer do the same adjustment without causing me headaches.....concerned with this request it will open a can of worms. Not familiar with local dealers for Ram but with other brands they have all been less than cooperative and ignorant to simple changes.
