How fast do shift patterns adapt

[DHalsey]

I've used the search extensively and haven't found an answer to this. I have a little over 500 miles on the car and am wondering.

How fast the car will start learning my driving style?


I copied this from a thead I found.

SHIFT SCHEDULES
The basic shift schedule includes up and downshifts for all five gears. The TCM adapts the shift program according
to driving style, accelerator pedal position and deviation of vehicle speed. Influencing factors are:
² Road Conditions.
² Incline, Decline and Altitude.
² Trailer Operation, Loading.
² Engine Coolant Temperature.
² Cruise Control Operation.
² Sporty Driving Style.
² Low and High ATF Temperature.

ADAPTATION
To equalize tolerances and wear, an automatic adaptation takes place for:
² Shift Time.
² Clutch Filling Time.
² Clutch Filling Pressure.
² Torque Converter Lock-Up Control.
Adaptation data may be stored permanently and to some extent, can be diagnosed.

Driving Style Adaptation
The shift point is modified in steps based on the information from the inputs. The control module looks at inputs
such as:
² vehicle acceleration and deceleration (calculated by the TCM).
² rate of change as well as the position of the throttle pedal (fuel injection information from the PCM).
² lateral acceleration (calculated by the TCM).
² gear change frequency (how often the shift occurs).

Based on how aggressive the driver is, the TCM moves up the shift so that the present gear is held a little longer
before the next upshift. If the driving style is still aggressive, the shift point is modified up to ten steps. If the driving
returns to normal, then the shift point modification also returns to the base position.
This adaptation has no memory. The adaptation to driving style is nothing more than a shift point modification meant
to assist an aggressive driver. The shift points are adjusted for the moment and return to base position as soon as
the inputs are controlled in a more normal manner.

Carefully read the last ten lines of your post.

I did. Does anyone have experience with how long it takes to go up the ten steps of shift points that were mentioned. Hours, days, weeks? Do I have to flog the car all day everyday to get the best performance?

when i'm concerned about performance and shift points, i take matters into my own hands and go into AutoStick mode.

The car I test drove at the dealership was the owners car. It had about 3000 miles on it. It would bark the tires into second gear everytime in Drive. When I bought mine I assumed that it would do the same. ( I didn't flog mine at the dealership because I new I was buying it, and about the break in). Just wondering if there is that much difference car to car, or if his was just a freak..

IMO, the car only keeps the aggressive shifting pattern for a very short time, probably 15 seconds or less. Lighten up on the throttle/shifting and the car will quickly revert back to the base position. But I have no proof of this.

The SRT engineers say the car adapts/learns within a few minutes.

SRT Engineer Answer to question about removing Fuse 11
Removing fuse 11 removes the battery feed to the engine controller. A couple minutes of being left unplugged will clear your adaptive memory. This forces the engine to run at pre-programmed state that is not optimized for you specific vehicle. Within minutes of starting the engine the adaptives will be relearned (this is a good thing) and the engine will perform at it's optimum levels.

ok, so the fact that the car I drove at the dealership had very firm shifts has nothing to do with the TCM?
Are there any limitations set on the computer during the break in process?

[arnoldw]

You'd think that if both cars are identical that they would shift basically the same way.

did one have the "flash" and the other did not. Since the TCM flash "preloads" 2nd that may be why the shift is "harder".

just my 2 cts. JP
