I want 6200rpm shift points in my C5
I just got a new ECM installed, so my tuner is going to redo my dyno tuning again for free, instead of using my old tune. This time around I want to go with even higher shift points, 6200rpm to be exact (they were around 6100 before)
But I remember when the tuner was inputting the shift points in LS1 edit, it asked for the mph of each shift point. So I'm curious as to what mph is needed for each shift point in a 3.15 geared A4 C5 in order to achieve 6200rpm shifts on the 1-2, 2-3 and 3-4.

This might help. Work up from your stock settings.
REAR AXLE RATIO 3.15:1
1-2 SHIFT ------------------2-3 SHIFT--------------------- 3-4 SHIFT
1 MPH = --------------------1 MPH = -----------------------1 MPH =
121 RPM --------------------65 RPM ------------------------40 RPM

Thanks a lot, that will help me out big time! Do you happen to know what the exact stock shift points are? Looking at my tach it appears like they are around 5700 from 1-2 and from 2-3, although sometimes it looks like it's shifting even sooner, at 5500.
If the stock shift points are 5700, it looks like I'll need to go about +4 mph on the 1-2 and +7mph on the 2-3 shift.

Now I'm very confused. Someone on one of the Corvette forums told me they calculated the following mph in order to get 6200rpm shift points in a 3.15 A4 car:
1-2 at 50.7 mph
2-3 at 93.8 mph
??
1-2 at 50.7 mph
2-3 at 93.8 mph

OK, I think I might have the answer now!
Someone on Corvette Forum mentioned that both of the parameters need to be met in order for the shift to take place, so that if I set the mph of the shift to a slightly lower point, but input 6200 as the rpm (in LS1 edit) that the shift will occur at 6200. If I were to set the mph at exactly where 6200 would be, then the shift would end up occuring after 6200, since it waits for both parameters to be met first (and I assume if both parameters are at the same point it slightly delays the shift as it might get confused?)
So perhaps the mph isn't even that critical, I could set it to 45mph and 90mph if I wanted to, but as long as I have the rpm of the WOT shift set to 6200, it should make the shift at 6200. Does this sound correct? (I know a lot of you must've played around with shift points in LS1 edit!)

I don't think your car will benefit, performance wise, from higher shift points unless you are going to a bigger cam soon.
In stock form, the motor makes peak power at 5,600 rpm and peak torque at 4,400 rpm.
