I did not ask on my last visit.I understand that new calibrations are updated routinely as the software is updated. They plug in a laptop(Ethernet) to the truck, will respond that updates for the VIN are available, if so, tech initiates. 10 min, done deal. My truck was calibrated in Jan, again two weeks ago,oil change visit, (I have the oil/lube package,cheap) Warranty Bulletin D-0912 dated June 2009.
To: Dealer Principal, Service Mgr, Parts Mgr and Warranty Claims Administrator.
Purpose: To announce a change in policy regarding electronic control module"Service Flash" updates wiTECH
Timing: Immediately
Background: In an effort to delight the customer and enhance the experience on the Service Drive, we are now promoting the usage of wiTech to pro-actively provide the customer with the latest module software available for their vehicle at every service visit, without waiting for a specific symptom to occur. This action supersedes the previous policy requiring that a customer wait for a specific symptom before executing a flash operation.
Apparently, the code title(flash) is meaningless. If you go for service, they hook it up: YOU GET IT.As outlined above,my truck was calibrated in Jan, again in Mar this year. The remaining body of the bulletin, is tech stuff pertaining to warranty application etc and wiTECH. I never ask what this or that is.(truck performs great) I don't care because I am stock.Not positive; but by refusing performance enhancing updates may impact the warranty in some way? Probably could call a dealer.
