Drob, if i'm recalling that trap is way up. Any software revision or new mods since then? Different conditions?

Mike

Maybe unicorn 93 gas? :) But I am curious what fuel/octane you were running Drob!

Also went to Milan. Had a great time with a bunch of forum members. I managed to get a new personal best, looking forward to improving from here. Video credit to madman4you!

Thanks man, yea the trap is great, et should get better with an improved launch. Pretty sure the improved trap is largely due to the amax mode with the tcu tune. But yea, great feeling to know the car is running right after so much uncertainty regarding knock issues.

Having slightly faster shifts would improve ET. You have more power if you got a 5mph faster trap. If you were retarding 8 degrees (regardless of the reason) and now just a couple degrees you are effectively using 5 or 6 degrees more timing. Thats significant and where you get 5mph improvements in trap. As an example the other APR stage 2 car there running 104 octane ran the same 116mph trap. Thats timing. He got a better ET but you improve you 60ft and so will you.

You do realize that the TCU tune increases power significantly , right? Max hp is at max redline...

[AZT]

I think he was responding to Drob specifically calling out AMAX mode behind the increase in trap speed. If you are talking about the general redline increase for B8.5s, yes that should result in higher average horsepower and trap in the quarter. I recall in whole that APR saw a little over 1 mph gain in trap with the TCU tune on a B8.5 Stage 2. Advancing another 6 degrees with increased octane / E85 (as Drob had mixed in) would have the bigger impact IMHO. These cars love octane and especially some E85.

According to the thread, 35whp gain, probably just as significant as the octane level

Didn't see who arrived at 35whp, can you link to the post? I saw APR quote the new RPM power peak was 20-30 crank horsepower higher, though in the chart the 93 octane seems closer to the 20hp figure or 15whp. Which would align with a +1.5mph trap I suppose and it appears that's what they got.

6400 rpm to 7200 rpm is huge. APR claims '20-30 whp' on their website, but you can see by the graph that they are saying that conservatively , look at the 91 octane line.

Arin, you accidentally listed me as stg 3 Or is that code for TCU/ECU tune since you are listing the blower for the actual "stg 3" guys?

[AZT]

It looks like that graph on the TCU page is in crank HP and I still don't see what you see, but if I go over to the stage 2 B8.5 AWHP dyno graph, it is definitely not even close to a 20whp increase from 6400 to 7200. I realize this is probably a different test, but in general it seems like the B8.5 dyno curves on the ECU page aren't quite as optimistic in their climb between 6400-7200 as those on the TCU page.


With that said the average HP probably does jump more (as you get into the higher gears) from not dropping to as low an RPM in the next shift than just the peak increase would indicate. Maybe that is the number APR is getting at which you can't easily see on a chart. I am interesting in getting the TCU tune myself.

You are too focused on peak HP. That is not the most important factor, what matters in acceleration testing is the area under the curve. The transmission was shifting at 6450 before the TCU tune and at 7200 with it. Which means you shift to a much lower point in the powerband in the subsequent gear. The b8.5 gear ratios were changed from the B8, which lead Audi to change the shift maps (or red line) to maximize power using the stock engine calibration. Now that peak power continues to red-line with stg 2, there is a huge benefit to revving the car out.

And for those of you not following the bickering on the other site, my point about the TCU tune being a huge contributer was directed towards this being a great trap relative to the other pump times on board, especially given how my et's weren't great.

This picture... and it says on the side AWHP...

I only see Horsepower [ HP ] on the side, not [AWHP] like in my graph, so I don't know where you see that. Anyway we know Stage 2 91 octane doesn't make 450 whp.

Yes, that one graph shows crank hp. It also proves how much power a dsg flash can give

[MVR 155]

Looks like the TCU tune is good for a solid 20-25hp at peak RPM but as blaze pointed out earlier..... it put's the car into a better power band after every shift which amplifies the results. This will without a doubt equate to better trap speeds.

Seems like you could calculate the average HP gain (area under the curve) knowing the before and after shift points. In the other thread it was pointed out APR saw a 1.5mph increase in trap before and after on their car.

I think a 1-2mph increase in trap speed sounds very reasonable with the TCU tune

So now Primetime, Ryan and Jeff are all running upgraded cranky pulleys.. I'm still the fastest stock crank pulley car :)

Since Prime and Ryan have crank pulley, shouldn't they be classified as APR 2+ since you listed GIAC as 2+ with the crank pulley? Just to make things less confusing since they're not running that fast with just basic Stage 2. An extra 2-3psi def makes a difference ;)

[Arin@APR]

Lots of new times. I'll update them but I need a desktop. I'll be in sema all week so I may be slow.

On the tune section, it was intended to be the tune the car is running. So if it's XYZ's stage 1 tune for 91, but they had 104 in the tank, it would help the reader understand the results were not with a 104 optimized tune. The hardware notes section should list all the relevant mods but that's gotten sloppy and out of hand. I'd almost like to make it a link back to the persons posts, and maybe with a few key mods listed for quick browsing.

I wonder how much longer it takes you guys to realize that one of these times was an A4?

This. The 3.0T is octane hungry. Better fuel directly correlates to better results.

That trap finally matches the ET. Nice. I know you mentioned you were going to clarify that you had a mixture of e85 in your last "93" run. I'm sure you'll get around to that. Did you run straight 93 this time or mix it with e85 this time?

How much of a kick do you think those test pipes gave you? Did you have to dismount the engine in anyway to install them?

Would have had a chance of besting you had my TCU tune LC worked properly. I don't know regarding the test pipes, it's obviously less restriction, but many before have shown not many gains to be found with exhaust modifications. But the test pipes certainly don't hurt. Removing the cats is a disaster, I didn't switch to test pipes by choice per say. You can read about it here http://tinyurl.com/omjynsc

Yeah launch control can be finicky at times. What exactly happened with you this go-around?

From the little I've seen, the cats are where most of the restriction lies, but until pushed much further by something like stage 3, doesn't seem to be worth the headaches.

As for the times, good luck! I'm not going to deny enjoying sharing the top for 93 on 93 but I'm all for friendly competition and getting the platform records as low as possible on each general setup.
