QUOTE=billvp218;7984657]Anyone have it for the 7-speeds?[/QUOTE]
Here's what I've used in the past, among other calculators.. if trying to determine optimum shift points for our car... its simple... shift near redline...at least for my torque curve.
This is for the AWD 7 speed.
That is a simple graph generated from the gear ratios, final drive and tire diameter, limited by rpm... nothing more.
There are other graphs out there that go one step further and account for your power profile to maximize acceleration by determining your optimum shift point based on your individual torque curve.
Here's the data for my car based on my dyno plot...
You'll notice that my torque profile indicates to maximize acceleration I need to take the car to almost redline in every gear. This is specific to my torque profile which is very flat... those of you with peaky profiles aka older tunes with large torque spikes down low, you may want to look at this calculator and input your own dyno profile to see what your optimum shift point is... it may tell you to short shift to optimize torque and hence acceleration...
^ This old brain of mine have no idea what you just posted. Was just hoping for simple numbers...like fuel cut-off occurs at 5k rpm in gear 1, 6k rpm in gear 2, etc..... so I know when to shift before cut-off occurs.
If your tune is good and you have the necessary supporting mods required, then you shouldn't see fuel cut-off at all... at least until the rev limit is reached.
Even stock allows you to run all the way to redline in every gear, only speed limited by your tune... I think 155 mph for non S models, and 186 for S models... I could be wrong here though.

Thanks for the link. Your entered gearing looks nearly identical as what I've found for the rwd SL63 7-speed, although what you have shown for the final drive ratio is what I see for the reverse ratio ... I have seen 2.65 for the final drive ratio. I also have redline at 6250. Do those speeds you posted look correct to you (2nd gear only going to 47mph)? Here's what I have for mine. This looks about right, I'd roughly estimated that 7th gear would hit around 250 at redline, and the car shifts at redline slightly before 135.
