, for example, makes the shifting more aggressive. If a customer gets an unrequested change in acceleration profile and complains about it, the dealer can't undo the TSB and is SOL on his customer satisfaction survey.
The update is to refine the profile. While some parts are more aggressive (holds gear longer on part throttle) the overall effect is a much smoother vehicle. And, since every WK2 built after the date listed in the TSB gets the new software I don't think it would cause that much customer dissatisfaction. It is quite simple though, ask the customer what they want and DO what the customer wants, not what corporate says they want you to do.
I can't imagine anyone who bought the Hemi having any negative comments about the new program. In fact, unless you were doing a back to back comparison you wouldn't really know anything had changed aside from the 1-2 upshift not banging into gear and the truck doesn't buck when you are trying to maintain a constant 45 mph.
The one that gets me is the 4WD error code update. No one who hasn't have the error will request it BUT, the error is caused by using the truck in a demanding 4WD situation which will leave the vehicle stranded. So, the dealer can spend the 0.2hrs updating the control software or pay for the 100+ mile tow to get a disabled vehicle back to their lot along with having to pacify as really pissed off customer. Jeep didn't thing that one through.
I've had Porsche's, VW's and Volvo's that got every update as a matter of course and customer satisfaction has never been a problem. The old code had a problem or they wouldn't have taken the time to correct, test and QA the new code.
The bottom line for me is I want my January built WK2 to be as up to date as the last 2011 that left the assembly line, period! Just give me that option, don't play the "you have to have the problem to get an update" game...... Luckily my dealer didn't make me play that game but the poor soul who doesn't have access to this info is SOL.
