Been reading but still somewhat unclear. In HP Tuners
(First with the gear swap It does just go right to rev limiter)
So first I adjusted the gear from 2.73 to 3.73.
Next do I have to lower my WOT shift soeed. Is this just trail and error. right now its at 1-2=46mph 2-3=93mph 3-4=255mph
Drive car at rev limit notice speed and -2 mph and try that???
Thanks
Dennis

Reset Gear/Tire Size (you did that) and rescale
rev limiter is probably set at 6200 (Stock)
Set WOT Shift RPT vs Shift points for Normal/Perf/Hot to 5900 or 6000
This is my Shift Speed vs. %TPS vs Shift table (copy to normal, Perf/Cruise/Hot): Yours can vary from this but this may be a good starting point.
Your WOT shift speed is ok but you may want to try:
45
88
143
42
90
128
Play around with it though to see what you like. Same goes for the above tables.
If you want, I can email you my .BIN file (which I've "borrowed" a few tables from others) and you can look through to get an idea of any other changes you may want to make such as A4 Shift Properties and A4 TCC.
Also, under Engine/Fuel/Fuel Cutoff make sure your Cutoff RPM vs. Gear is is also set at or below your rev limiter.
ps: Check your Diagnostics screen and make sure your P1870 Trans Component Slipping table is something like:
72
279
800
80
40
-20
279.1 600
277.7 5
Ussually when that happens and there is no reasonable explanation from a programming perspective you've got slippage in the tranny between gears. Unfortunately, that's also a sign the tranny is on it's way out.
I'll email you a copy of my .bin file. But for a further test, try shifting the car manually down to second and third and back up and then stab the pedal in each gear. If it's slipping, you will know it.

I've tried manually shifting and down shifting, I don't feel any slip at all, going to second it will spin the tires and going to third it pulls strong.
Could you send me a copy of your bin file? I'm can't get mine to shift 2-3 below 6100 rpm, there has to be something I'm missing.
My mods are 3.73's, blackwing and Corsa exhaust and that's all.

It's believed that both shift speed and shift rpm parameters must be met for the trans to shift at wot. I set shifts on that basis even though I'm not sure it's true. Try lowering the mph threshold.

I noticed yesterday that I still have my WOT RPM values at 3000 from back when I was trying to figure out why it wasn't shifting where I wanted it to. I don't shift at 3k so I can at least affirm that the WOT MPH values are required. I don't remember ever doing something like setting it to anything above the rev limiter and verifying that it was also required. I'm not always as thorough as I aspire to be.
BOWTYE8, I'd be looking for something more like 65-70 for your 2-3 shift, depending on your converter. Your idea of observing your speed at your target RPM is not a bad first guess and is a decent substitute for trying to compute what it would be. Once you're in the ballpark it does require a little trial and error to get it dialed in, but it doesn't have to be a completely random first guess. FWIW, I find it easier to work up to it rather than down from not being able to shift. It also means I don't have to think too hard (always a plus) about getting in the ballpark initially.

Topless,
I seem to remember we were part of a thread on this subject about a year and a half ago. It seems that whichever of MPH or RPM is set higher controls shifts. It's easier, for me, to set MPH lower and use RPMs to get the desired shift. Moving RPMs some value doesn't result in an actual shift change of the same value, with my car. It takes some playing to get the actual right.

IIRC, when I was last really playing around with my shift points I was wrestling with some buggy software and trying to understand what was up with the speed condition. (The speed value wasn't being computed correctly relative to the gear change and we were trying to figure out why.) I agree that whether you try to match the two criteria or rely on only one or the other, it requires a little experimentation to get it where you want it.
A reason I might choose to favor one condition over the other is if it gave a more repeatable shift point. A downside might be introducing inconsistencies with the part throttle tables where it transitions to WOT shift mode. I never seem to have the time and patience to play with things like this anymore... I'm curious now though, and also want to think a little about what the logic might be behind the intent of the two conditions. I haven't thought about it much but my first guess would be to prevent an early shift. Something for me to think about while sitting in today's meetings.
I just had the same problem, took a while to fix, it turns out that I needed to adjust the settings for the pulses per revolution. If you are still having the problem, try that.
