Hypertech Question - Reassigning Shift Points on a 2000 A4
Just got my Hypertech PPPIII and want to begin programming. I am going to raise the rev limiter to 6400 RPM to start with. I have stock tires and the 3.15 performance rear.
My question: Do any of you current Hypertech owners out there have any recommendations as to where I should set my 1-2 and 2-3 shift points for starters?
I read the manual and do not have the luxury of going to the track to beat on the car for 15 - 20 runs to decide which shift points are best. Due to the similarity of our vehicles, there must be someone out there (or maybe even several owners) that already have this process pretty well figured out.
I also would like some info on resetting the shift firmness. The options are 25%, 50%, 75% and 100%. How much of a difference is there between each of these settings? Has anyone installed a shift kit after making modifications to the shift firmness using the Hypertech? If so, was there a marked difference in how well the vehicle shifted before and after?
Thanks. All advice is welcome.

I am at work and can't remember how much I increased the shift points, but I know that I set my limiter to 6200 and increased the shift point by at least a couple of hundred rpm. I set the shift firmness to 75%...100%, I thought, was just too firm.

Re: Hypertech Question - Reassigning Shift Points on a 2000 A4 (B. Stewart)
With your mods, 6,000 RPM shift points would work well. I'd bump the limiter up to 6,300 just to have it out of your way. If you add a set of headers later on, bump your shift points up to 6,200. That's where I was shifting with stock internals since that's how far my engine carried power out before declining.
As for the shift firmness, I wouldn't go over 50% firmness. All the HPP3 is doing is raising the trans. line pressure electronically. Too much line pressure will kill a trans quickly. I'm not a fan of raising the line pressure electronically to be honest. I would personally have a TransGo shift kit installed. Be sure to NOT raise the line pressure electronically if you do have the shift kit installed. This will set the line pressure too high and kill the trans.

Thanks for the advice. I'll start with your recommendations on the shift points and work from there. It looks like a shift kit may be the next investment so I can keep the stock line pressure while enjoying the benefits of increased firmness while shifting.

The HPP3 doesn't raise the maximum line pressure. You are plenty safe using the shift firmness feature. :) Lots of us have lots of miles after having done that.

try this
Shift firmness @ 75%
1-2 shift - +2mph(snapped neck)
2-3 shift -+4mph (snapped neck)
3-4 shift no change

Re: Hypertech Question - Reassigning Shift Points on a 2000 A4 (jawski)
The last reply pretty much sums up the research I did a while back. Lots of disagreement re line pressure/trans life. Some said early death, some say longer life with greater firmness!?! I do know that one downside with increasing the firmness beyond 50% with my 3.42's is that the TC will activate on the 1-2 shift! :D

Re: Hypertech Question - Reassigning Shift Points on a 2000 A4 (C5XTASY)
Right now I am at 75% firmness with +2 on the 1-2 shift and +4 on the 2-3 shift. I left the 3-4 as it was. So far no problems. I am going to try driving it a while like this and make any necessary adjustments after I get the feel of the car.
When I programmed my car, the Hypertech module indicated that the tuing was completed, however, just as it finished, the DIC on the car came up with a reading that said "Reduced Engine Power." Has anyone else noticed anything similar?

Re: Hypertech Question - Reassigning Shift Points on a 2000 A4 (C5XTASY)
Last fall, when first trying out the Hypertech, I used +2 on the 1-2 and +5 on the 2-3 with 75% firmness. I left the rev limiter at the stock 6200 rpm. I banged the rev limiter on both shifts. So, I lowered firmness to 50% and the 2-3 shift to +4. No problems then. I may try 75% firmness again when the weather warms up, and set the rev limiter to 6300 rpm. Set your fan turn-ons a little lower, too.

The Hypertech screws with your dash read-out. The programming always seems to work, but I've had my entire dash go down (i.e. you can crank and run the car but all the gauges read "0" and there's some odd error message like "reduced engine power" on the display. You just have to hook the programmer back up & let it re-establish communications and then cancel back out of the install and the dash will come back to life.
I don't know what causes this. Maybe it's a dip or spike in voltage while you're programming.
This really freaked me out the first time it happened. The dash just needs to reset. There's a way you can reset the dash with the gauge bottons (something like hold down the reset button while pressing the fuel button 4 times) but that never seemed to help.
