A6 shift points are ?





On a stock A6 ('08 if it makes a difference) what are the minimum speeds that the trans upshifts and downshifts for each gear?
Are the speeds different for Drive and Sport?

I did my own tune for S mode only and it is more aggressive than the S mode table above. It makes a world of difference and takes all the sluggish feel out of it at low throttle %.

What makes things even more interesting is that "Normal" is also considered to be Drive and since you can enter different values for each, you could end up telling the computer that the same mode needs to behave differently.
I tested this one day and found that if you have different values in Normal than you do from Pattern B, the Normal values will take precedence (if that makes any sense whatsoever).

If A is Drive and Normal is also Drive and B is identical to Normal.
That would mean everything is Drive.
On the other hand we have B as Sport that is identical to Normal? If B is identical to Normal and B is Sport, then Sport forces earlier shifts.
Just looking at the speeds for upshifts at any %TPS looks like Normal would be Drive because they are earlier than A.
If Normal = B = Drive and A = Sport, then I understand, otherwise I'm totally lost and need a brain transplant.

One more thing to ask. Are those charts for a 2.56 gear or the 2.73 gear?

I recently had a tune that moved those values in both D and S. I'd like to know how far from stock they were changed, so I can more correctly identify what my personal driving style would be most comfortable compromising toward. For example, in S my present 1-2 shift at light (6 or 12%) throttle is 20mph, which is too high in comparison to stock at 8-10mph. So maybe 13-14 would suit me better than 16-17 or 10-11.
Yeah, I think I would have an interest in seeing all the values including the 4-5 and 5-6 shifts too. I'd appreciate that very much, thank you.

One would think that the sport mode would stay in the gear longer before upshifting (higher mph figure) (for both part throttle and WOT tables) and also downshift sooner (higher mph figure) as compared to the drive mode.
The only table shown on this thread that matches that theory is Table A shown by Dave.
The Drive tables would have the lower mph figures to make them a milder (sluggish) shift. Both normal tables shown have this. This makes sense.
So Pattern A cannot be drive or normal because it has higher mph numbers not lower. We can't be calling a table with lower numbers the Sport table! It does not make sense.
My LS2 Edit program has 2 tables, labeled Normal and Sport which match my higher mph figure theory stated above. Very simple and easy to understand and use.
Hp on the other had throws in pattern A and B and normal with mph numbers that contradict what we would believe to be true.
Can someone give us the final word meaning which table do we adjust for Sport ( this un modified stock table should have higher mph before we touch it) and which table do we adjust for Drive ( this un modified stock table should have lower mph before we touch it).
Then please tell us what to do with the odd ball third table. Leave it alone or make it match which of the other tables and why is this third table even used?

In regards to the numbers not making sense, the one thing I forgot to mention earlier (and it probably would have caused less confusion if I had) was that my car has 3.42 gears and I've modified my shift points based on the fact that I race the car.
Sorry for the confusion as I was only trying to show what the different screens looked like, not what the numbers should be for a given car.
Hope that clears things up (even just a little).

It also appears in the "pressure pattern select" menu
that there are only two choices (X and Y), which causes the changes you experienced in Normal to be duplicated in either Pattern A or B, depending on what the setting was in the type menu.
I'm guessing you have toggled one or more of those settings and that's why your information differs from DaveC6 who may have toggled his from stock too.
At this time, my concern is only with the stock shift points, so I don't ask the tuner to do something that becomes less than what I got from the factory.
I appreciate all your help.

BTW, I got a laugh about the max speed of 318 mph on the bottom right.

Let me know if you'd like to see all of the shift values for your car and I'll post them on Photobucket.

The reason for the pink coloring is that I only had a 2.73-geared tune as my starting point so when I switched everything over to 2.56, the pink represents the values that were changed.
Hopefully this will give you everything you wanted to know but if it doesn't, just let me know and I'll do my best to help you out.

This has to be from an 08 with a 2.73 gear. My 07 will downshift into second gear at 60mph with 100% throttle.
