Update on my car, all is well, love the Track Cal and will never go back to stock. Occasional detonation under the right throttle "roll-in" conditions but not enough to make me want to activate the octane adjust feature just yet. I have noticed also the occasional "re-set" of the lopey idle back to the smooth idle for another 2 minutes if I'm "lugging" the car in a parking lot too much. Probably a default in the program or a "my-fault" for lugging the engine too much.
I got tired of the pinging and activated the octane adjust feature. (In CA we only have 91) The car no longer pings and it runs a bit snappier, runs better all-around. I'm sure this has everything to do with detonation causing the knock-sensors to remove timing. I'm not going to lie I thought the feature would have made it slower but it feels like it did just the opposite. ...I'm curious if anyone else can chime in on similar results??
Old thread, but I'm looking for some follow up from those with the Track Cal. I am *very* close to pulling the trigger for my 2013 GT. Has Ford made any updates since Decemberish? It looks like the Track Cal is now self-install and no trip to the dealer is necessary unless you have the key.
