Time slip enclosed, want 11's.

I did not make it to PBIR last night due to working late, and the track was crazy from what I heard. Oil on the track and a cobra spun out and hit a wall. Mike ran an 11.8 though, which is great. I will try again soon, hopefully it stays cool down here. I did walk an SRT8 on the I-95 though, he got off at the next exit. Lol. I cars are pretty darn stout, especially when it is cold out.

Bummer conditions looked great last night. Both Mike and the S6 that was there ran great times.

Hey Rick, let me know when you are heading out to PBIR again, shoot me a PM on here or Audizine. I have my Avant back and need to go. I’m going this Saturday - 2/20 - it’s a Street Racing made safe event (allow roll races but no et or trap is displayed) so it’s not your typical test n’ tune. There should be a RS4 coming out to play as well.

I sent Jeff @ Revo my logs from a couple runs in 78 degree weather recently. Here is his reply about my Revo 1+ tune.

Rick,

Ah, my apologies, I had a log open from a dealer seconds before opening the one you attached and it was the wrong screen. We are very very familiar with VCDS; that’s not the case.

The bleed off is normal, it is hitting requested boost and pulling back a little; we request .92 and you are hitting 1 in higher RPM. Timing is fine and starting to pull slightly as it should and temps are still creeping up. If it was warmer out or other elevation this car would be struggling to make boost like most do. This happens to be strong - good.

I’ll copy my response from the other site below:

He basically responded with what I would have expected. He’s saying the specified pressure is setup for average conditions, and because you are at a lower altitude in good conditions, you are going to bypass for that reason. In those conditions, they are limiting you to about 2100 hPa specified pressure (about 30.4 psi). Depending on ambient pressure, that means you are limited to something around 16 psi of boost.

The counterpoint to that is Mike’s Uni tune in the same conditions didn’t bypass, and he had basically the same timing. His Unitronic tune maxed out at 2223 hPa (32.2 psi). My APR tune doesn’t either, and I was hitting the same 21 degrees timing last week on the dyno. I topped out at 2300 hPa (33.3 psi). The GIAC logs I have in similar conditions has similar timing, and top out at a crazy 2600 hPa which isn’t even achievable with a 2.5 bar MAP sensor… I literally have logs from every other tuner that look nearly identical to yours minus the bypass.

I definitely agree that the amount of boost you are making is strong and good. But, I’ll stick to what I originally said, and say that I don’t see why it really needs to bypass there. The small amount of timing pull is not an issue at that point. There is nothing wrong with tuning it that way. I am sure they do feel it’s safer to limit pressure when running slightly more aggressive timing, but limiting you to 2100 hPa of pressure is going to limit you from the best possible times at the drag strip. It pretty much explains why you won’t see a record time from Revo. Your car is fast, but it’s also leaving a little meat on the bone if you really want to run the fastest time possible.

Helpful post;

Thanks for putting it here as well.

very helpful, probably the best explanation of what limitations Revo has in their tune that I’ve ever seen.
Thanks

Hello all

I waqs searching about for revo 1/4 times & cam across an 11.985** 2015 Audi S5 Revo Stage 1+ (1/4 Mile)

gives hop to us 1+ guys

haha this is Fireball the guy i was talking about in my earlier post. he has actually ran a faster time then that. This season he should be a bit faster as he now has some of my old LW parts
