Renntech Intermediate Tune Only 11.51 at 129.63mph
Made a few passes at Famoso Raceway at the Team Spankin Time private rental. Weather was pretty good with DA in the 300-1000ft range all day. I ran stock Conti street tires, so traction was a big issue out of the hole. I was very happy with the consistent 128-130mph trap speeds, but obviously ET suffered from poor 60ft's. I will have some proper tires for the next event and hopefully can hit 10's.
Attached are my best couple of passes. Car ran full weight with 95 octane chevron 91 and vp 100 blend.

I'm confident this car as is has a 10.7 at 131 in it with proper tires and a good launch.

Actually there was minimal spinning. I learned after the first pass that the only way to get off the line was to just very slowly ease on to throttle with a lot of restraint. With drag radials would have been able to floor it from the start and likely even pick up a mph or two.

I ran 11.2 at 127.7 with weistec tune but had also installed mbh catted downpipes and did not retune for them...i just got a retune for them and feel the car runs better but tracks are closed for the season so have to wait a while..

Love the trap speeds--- How much more hp are you gaining from the fuel upgrade? I hate that cali std is 91---
I wonder what my SL63 would trap with that tune? I am a little lighter right?

Actually, your SL63 on the same tune should trap about identically since our curb weights are similar according to mbusa.com (4,048 for 2013 E63 vs 4,068 for 2014 SL63).

Thanks for the comments. Next private rental may be as soon as next month. January historically averages the best weather conditions, so if we're lucky enough to run in conditions closer to 0 DA, might be able to squeeze out a 10.6x at 132mph pass. That would assume a low 1.7x 60ft. Pretty amazing what our tune-only cars are capable of!

Thanks Vic. Not sure how much extra the 95 octane is giving me since I never did a dyno comparison, but my guess is maybe 5-10whp since it's a 91 octane shelf tune and can only dial up parameters minimally.

Interesting, I expected the hp/tq to be higher based on the 4 pts octane gain...APR recently tuned the Audi RS7 and here is what they got from the different octane numbers; the 2 octane change (91 to 93) is incredible.

How could simply running 100 octane on a proper 91 octane map produce an extra 83hp?!?! If that's possible, then amazing how much adaptation ECU's are capable of these days. Also begs the question of why we would even need multiple maps for varying octane levels.

But don't these results reflect separate Stage 1 maps for each octane level? If so, then of course it's more the tuning adjustments for higher octane that are producing the big gains, not the octane alone.

Oh Im sure the maps are different--- dont our cars adapt well too?? I know with my Turbo Porsche I only had 1 map (91) but would screw with race gas the I could easily tell/feel the gains... maybe the DME's on the Audi and Porsche are more flexible to fuel variants?

There's no way for a car to sense the octane of gas outside of watching for knock. Many manufacturers (including Ford with their new EcoBoost truck that advertises more torque if you use higher octane) have a soft series of timing advance maps that some algorithm moves up and down as it senses knock.
That said, you can vary the aggressiveness of the timing "yank" that occurs with the sensation of knock in one or more situations. I'd be slightly cautious about how aggressive tuners push the timing and boost if they dont have an equally aggressive removal.
That said, the ECMs are not going to just add boost and advance until they sense its too much and then back off a little. Each of the maps are specifically retuned, retested, and (I hope) carefully watched under a variety of environments before they advertise them.
Octane produced no gains by itself... in fact higher octane fuel has *less* energy density than lower octane. The car has to take advantage of the octane to make more power from the remaining fuel.

That said, now-a-days direct injection has made fuel timing important. If the car can carefully adjust the timing of the fuel injection to optimize much higher-than-stock boost flame travel and whatnot, then maybe (maybe) the car can learn in a little extra power (but no way 83).

11.5 is nothing to be sad about.. but 129 is really good for a tune and drop in filters.
I'm very impressed with the RS7 tuning development.. not so much with the S6/S7.. seems like the bigger turbos on the RS cars really make the difference.
I would rather have the DCT on the S6/7 but seems like it not set up to handle that much torque.
E63 S 4 matic or RS6.. its really a tough choice.
Still hate the turbos are mounted on inside the V with Audi and BMW.. I'm not sold on that idea. But 4.0L TT in the RS cars is a incredible engine.
