Default An Observation We Made Today

My husband and I swapped cars today. They are both ( of course ) C7s. His is a Premier Edition #17 convertible mine is a coupe 2LT. Both have the Z51 packages. We both noticed differences between the two cars. I noticed that his brakes were touchier than mine and his steering is stiffer. He noticed that my accelerator was more responsive and my brakes not as touchy. We both run in Sport mode, not using the paddle shifters. The coupe was built in Sept and the convertible was built in Jan. Thought this was pretty interesting.

Thanks for the input, that is interesting. I suppose the differences are based on production variances?

Here is some food for thought. While I can't comment much on the steering other than to wonder if you are feeling differences in tire air pressure or if the steering settings are over ridden in the infotainment system settings and he has his set to track in the steering settings or yours is set to Eco Mode.

As for performance feel, the cars computer is a learning system. If you are really easy on the gas pedal, the car will (based driving behavior) kind of respond accordingly. If you drive with a heavier foot, the car will be more responsive and vice versa. The other thing that comes to mind is milage. If his car has really low miles, it's still not completely broken in. For example, my gas milage really seemed to improve once I hit the 2000 mile mark. That tells me that the cars performance will improve as miles are accumulated.

Both cars are set up the same. I have 4300 miles and he has 2987 miles.

Similar experience here, but same driver and same model car. I had VIN #00076 as a base Stingray manual, delivered in October 2013. I exchanged it for the exact same configuration (but with competition seats) as VIN #16589, delivered in early March 2014. I had 3450 miles on car 1 and car 2 now has close to 2000 miles.

The later production car has tighter and more responsive steering, a stiffer but more precise shifter, and an overall improved "driving feel" that communicates more to my body about what the car is doing. Car 1 lacked "thrill factor" on the road. Car 2 has it.

This is true in all modes.

Reportedly there was an extensive EEC S/W update in Nov. 2013 that is dealer retrofittable. Could this account for the differences ?

I can't answer your question, as I only have experience on one half of your comparison. My P.E. Vert (#125) is freaking fun.

Are both your steerings set up to change with the mode or is one set to a fixed setting? Double check because I believe the defaults are different based on the version of your ECM code.

The brakes could be different due to break in bedding or possibly the less sensitive one needs to be bled.

The throttle response is learned. When I picked up my Silverado the throttle response was horrid. Within 500 miles it was 1000% better. It learned my lead foot and compensated and the system is identical on all GM DBW systems.

I wonder if the computer can be reset after the engine break in period, to wipe the tame driving behavior from memory. My driving habits will change after the break in period, as I will be exceeding 4k rpm, sometimes quickly.

My Z4 35i computer could be reset. Nothing detailed in the owners manual. A Z4 owner posted how to do it on the BMW forum.

Love that technical explanation, Lisa. Ain't it great?
