Is it possible to make it display min/max values under each gauge? Doesn't need to be big text and the ability to reset would be good also.

I think the app has settings for it, at least it did at one point. But it's not really accurate or useful. Boost is sampled in front of the throttle body for example so when you let off the gas the throttle closes and the reading can jump up to 20psi or whatever for a moment, even stock. AFR moves around from 0-20:1 based on decel fuel cutoff, same for timing, so there are not a lot of parameters where it might be useful.

There are 2 spots for nozzles on the meth spacer.
Are there any plans to tap the o2 sensor to run a little richer? Do you think there should be any concern running the hybrid turbo at stock afr?

Default Audi B9 RS5 JB4 dyno testing - 12-20-2018, 03:07 PM

We managed to get a RS5 on a linked 4wd dyno for some testing. The car is otherwise stock running 93oct/98ron.
We used similar boost profiles to what the S4 uses.
Runs are map 0, 3 and 5 all on 93. Run 5 looked promising but not sure why the power dropped out. We ran out of dyno time so next time round we will evaluate.
In the midrange the gains are 50whp and 70ft lb giving the car a massive kick when on the roll.
We will be going back and testing a E85 mix and then will create optimized boost profiles for the car.

Initial impressions are that the torque can be raised by quite a bit more but there are challenges higher up the rpm range that might be due to hardware restriction or flow capacity from the turbos. This is one of a few cars that car going full bolt on with the mods so we will soon find out.

Is this version applicable for us SQ5 guys as well or just the S4?

George, thank you for sharing this. I am truly excited to see what new discoveries we find at the next dyno session. The gains from the basic S4 MAP thus far are quite significant over stock already. I can only imagine what will be possible with a B9 RS5 specific MAP. The question is, what will be the limiting factor? Will it be the injectors, turbos, timing, boost, etc.?

I will have the Roc-Euro intake installed before the next dyno session to see what gains are available from less airflow restriction. The AWE Touring Exhaust and Downp1pes should be in early January 2019. I am hoping to have performance catalytic converters ordered and installed at the same time to complete the intake/exhaust flow components of the vehicle.

Barring the aforementioned potential limitations, I am truly confident that 600HP/600TQ are within reach with the BMS JB4, complete bolt-on upgrades and a touch of E85.

Hello,

Im from Europe and Im driven S4 Avant, mileage ca. 10000 km.

There are some of my Dragy logs with full stock car (98 RON standard fuel from a standard cheap gas station, no race fuel, no e85).
The difference is not very big.

hm..... Is my car too fast or JB4 needs more agressive mapping?

It doesnt look like its accelerating any faster with JB4. Can you run some logs amd email to george@burgertuning.com and we can evaluate what its doing.

Well...I haven't had the code trigger again once I updated back to the latest firmware again. I'll keep my fingers crossed and let you know if it pops back up. Otherwise, all has been great.

Oh sorry guys, everything is fine. The car was full stock without JB4, the former screenshots of Dragy were without any tuning. Its S4 Avant.

Now I have my JB4 Thx u for amazing fast shipping vom CA to France

Everythin is fine, but I got today a christmas three with 0233F and failure of many systems, parking brake, ACC, PreSence ans so on. (Map3).
Conditions: fast acceleration from stop (without LC), sharp turn.

After restart of engine it was gone.

I took some measures on dragy with Map 2 und 3. Looks nice.

I'm still working on that one, slow going as only a couple cars can produce it. Set 6cyl timing = 10 to see if it helps.

George,

Any estimates on HP increase when using Map5 with E30 mix? Also, In having to supply race fuel or an ethanol mix at +6psi, is it safe to assume that this is the limit for the stock turbo/fuel pump?

I've had this on my SQ5 for a little over 2 months now, and it's been flawless for me. Took it off for a couple days prior to first service of the vehicle, and I was stunned how lethargic it felt without the JB4 installed.

I drive in sport/dynamic all the time. Throttle response felt like it was running drive/dynamic, and multiple times I had to flick the shifter to the left to confirm it was correct.

I find the SQ5 fun as heck to drive with the extra power. I usually grab the keys for it on the weekend for the family outings (for the space, cabin quietness and sound system). If I had to go back to stock (even though it's got a "pathetic" 354HP ), I'd be picking the BMW instead.

Super pleased!

Today I filled some E85 (20 Litre to a half full tank with 98 RON Shell gasoline inside) and filled the rest with 102 RON Premium Gasoline up.

Swithced to map 5... And I was surprised, the logging times are slower as with Map3 ans 98 RON fuel yesterday.

Is my mixed fuel all the same worse as Standard 98 RON Shell?

The log looks good. You 98ron run seems to be on slight down hill gradient so that could have a impact.
Does the car fee smoother overall vs the without the E845mix.

Maybe.. And today was very rainy. I ll try it tomorrow on same place as 98RON run.
Are there ignition retards in the log?

Intresting is lower boost in E85 Mix Run as in 98 RON run. Here ist the log (sorry very long, timestamp: 2050.50 - over 21 psi and 2534.50 -19.7 psi.

Thx.

PS: sh... too big for Forum.
