I have my '02 set at 6250 on the 1-2 and 6200 on the 2-3 now. Thinking about going higher but haven't been able to track test since getting LS1Edit.
I'm looking for what's working for the FASTEST A4 '01-'02s only. Thanks.

When I got my LS1edit done, I believe we set them at 6100, which I though for sure was going to be TOO low, but it sure wasn't! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I used to have it near the rev-limiter(6400) on both shifts with HPP3 - but the car always did feel like it was starting to slow before shifts..
Now, it feels like it's in one gear the whole way down the track, if that makes any sense. The high shift extension of these Yank's helps that too. So does my X-pipe - I'm at near peak power all the way down the track. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
<----this is Lane by the way. But I believe V6bird has similar shift points as well. Don't know for sure, and he probably wound't want that disclosed... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

LOL! Yeah, TQ rules man! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Hey Jerry, look me up sometime while you're down here. Maybe we can hit MMP one Friday? <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
V6 Bird, thanks for the help. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I'd like to hear from someone who has experiemented extensively with shift points at the track. '01-'02s only.
Ya'll see I'm just being lazy and don't want to do all of the testing myself! <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" />
I know one way you can tell that you're shifting to high is if the shift seems hard. That means your acceleration died off before the shift and that punch in the back was getting back into the powerband upon hitting the next gear. Right now I'm not feeling that at all on the 6250 1-2 shift but maybe just a twinge on the 6200 2-3 shift. That 3.06 1st gear causes a higher 1-2 shift to make sense. You gotta drop alot of power to make the 1.62 2nd gear worth going to. The 2-3 is much closer of course.

Hey Colonel,
Using only HPP3, how can I get reasonably close on determining shift points? The only options on the HPP3 are +/- in MPH that are converted using the table in the directions. For my 3.23's, it indicates 129 rpm per mph. OK, fine, but what are the factory set shift points I'm starting from?
Currently I set the rev limiter to 6300, and went +2 on the 1-2. It bumps the limiter, which surprised the heck out of me, since I thought stock point was around 5700, so I should be shifting around 5960 if that's the case. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
I have read a lot of posts on the various boards, and there seems to be a strong sentiment that the LS1 quits making good power over 6000 rpm, and anything over that runs a risk of valve float and its attendant troubles. Apparently you don't share that view - and I respect your judgement and experience. So clue me in on what's "safe", ok?
BTW, I'm trying to catch up with Lee Hurley at HESCO for a dyno session. Installed a cutout last week, SFCs and a QTEC electric valve are on the way. Probably won't be in before Steele on the 5th - we're going to SC to get our son from USMC basic (grads on the 3rd <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" /> ) Will you be at Steele for the shootout? Hope to see you there, the weather should give us a good DA. Never ran there.
Laterz!

Slapout? I have relatives from there. Heck, I even bought a Slapout T-shirt at the Boys Store (is it still called that?) <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
You can calculate your RPM by increase of MPH but that's only guesswork since your converter and transmission slippage are wild cards. The only way you will be able to truly tell how high you engine spins during shifts is to use a diagnostic scan tool like Autotap. You can monitor the RPMs very closely through a run if it's the only parameter you're monitoring (the more parameters you monitor in Autotap the slower the sample rate, at least with the DOS based version I'm used to using.)
Your factory shift point should be 6000 on the 1-2 and 2-3 shifts and 5900 on the 3-4 shift. That is set as 37, 76, and 125 MPH, respectively, in your PCM.
Correct, I do not agree that you shouldn't shift higher than 6000 simply because it's been my own experience (as well as that of all of the faster guys) that this is not the case. It's not hard to go out and try some runs shifting at 6000 and then again at 6200. Your trap speed and ET will be better with the higher shift point. Why is this? A couple of reasons. The LS1, with it's wide LSA camshaft, has a fairly slow drop off of power after the HP peak. It's a gradual drop off not an abrubt one. And, just because your power drops off in one gear doesn't necessarily mean that you would be better off in the next gear. Look at the gearing of the 4L60-E. Your first gear is STRONG with it's 3.06 ratio. You second gear is 1.62. You have to drop ALOT of power in first gear to make going to 2nd gear worthwhile. Remember, it's not the power coming from the crank that matters but rather what's making it to the rear tires. Gearing (both in the tranmission and rearend) plays a HUGE role in that.

My 11.41 pass was made with the hpp3 set at -1 1st and -2 2nd. My trans doesn't have a shift kit and shifts sloppy so the rpms are still at 6400 or so because any more on the shifts and it hits the rev limiter at 6500.

I ran 7.50 at 89.75 in the 1/8 today. Shift points were 6250 on the 1-2 and 6200 on the 2-3. That was the first pass of the day. After that the track didn't hook so well, the car was hotter, and the MPH dropped back to 89.3. I upped the 1-2 to 6300 and the 2-3 to 6250. The MPH went to 89.5. I bumped the timing up from 2 degrees more than stock to 4 more than stock. The MPH went to 89.59. Never did manage that 89.75 again but that was straight off of the road with nothing inbetween. This car seems to always MPH best on first pass. Plus, it hooked best on that pass probably helped the MPH a little too.
I still feel the 1-2 shift could stand to be a little higher. It flat pulls straight through the shift. The 2-3 seems about right at 6200-6250. More testing next weekend.

Other than you having a 01-02, why would exclude the '00's? Is there a difference in the program, or what?

Thanks Alien but this car won't make it to NA 10s internally stock. It'll keep the stock gearing and tight converter plus it won't ever be gutted at all. The goals for this car are to go fast in comfort. I'll let the HP make up the difference.

I'm not quote unquote one of the fastest bolt on A4s yet but I thought I'd chime in anyway. I didn't have much luck with adjusting shiftpoints by rpm so I just leave the rpm at 6000, the rev limiter at 6400 and adjust the shifts by mph. The 1-2 shift ends up being around 6250 and the 2-3 shift is around 6170...or is it the other way around? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

You would want your 1-2 shift to be higher than the 2-3 shift.
Adjusting with RPM seemed to work fine for me.

Colonel,
Thanks for the info. I'll tinker with it and see what results I get and let you know. When I met up with you at MMP in early Dec, you had the laptop in the pax seat. Were you running Autotap then?
I'm very interested in your progress with the NBM, since my goal with the white 02 is the same. No sense in reinventing the wheel - what works for you will work for me too.
The 12's (without converter and DR's) are the next goal. The correct shift points, decent hookup, and the new cutout should get me there)
Steele on the 5th - are you in?

I am running the HPP3 and I use the stock shift point on the 1-2 shift and -1 on the 2-3 shift. It always wants to hit the limiter otherwise. I have the limiter set at 6400. <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> I run it the same way on the N20 and the motor. I think the TQ management is killing me. <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />
