I have a FL DSG (MY19).. Here is a pull in gear 3 on map 2:
I don't seem to get any throttle closure at peak RPM, however I do get spikes pulling up the revs, but I think that is merely the ECU torque targeting.

Thanks for the info mate! However, it wasn't what I hoped to see of course
The thing is I can't really feel the throttle closure so it doesn't seem to be anything of major concern. Could you maybe try to uploade your logs to https://datazap.me/ ? It makes it possible for me to take a closer look on the different parameters.
Just a REMINDER for people updating to the new firmware and want to limit the boost in e.g. 1st gear: "The new firmware the values you put in is what it cuts so if you got a large value like 19 it will try cut 19psi giving you the issue. Start with 4 or so in order to cut what the JB4 is going to add and take it from there ."

And it seems like my "problem" with throttle closure at high rpm is in fact normal behaviour of the 7-speed dsg - as George explains it: "What you seeing is normal behaviour of the ECU and there is nothing wrong. ECU seems to close pre shift as a way to prepare for the gearshift. In the run its modulates the throttle to assist with torque targeting."
Logs from other members with 7-speed gearboxes on Vwvortex confirms this:

BTW this is my new map6 settings, drives really well even in hot weather with the RS7 plugs (35c):

Just some information from George (I know it's like I'm talking to myself right now, but I know people out there are searching for information and I just want to help).
I asked George about some codes that I have seen and couldn't find anything about them on google, so here we go:
3A6C
From George: Its a emission related fault. Post CAT fuel trim to high. Usually downpipe related.
The thing is that my downpipe is stock and I only have a resonator delete together with the exhaust valves coded out. George asked me if I had any exhaust leaks and I highly doubt this is the case but I will of course check and return if it is in fact the case. George would also look further into this since it might be related to something else but it doesn't seem to be anything serious.
3AD2
From George: The 3AD2 relates to fuel rail pressure. Typically caused by the fuel open loop value. It should be set at 45. If you getting a fault without a engine light you can ignore otherwise lower the value by 5.
Makes sense since I was running FOL 50 while getting this code. Mind you this seems to be the case with the facelift S3 since pre-facelift cars are running higher FOL when you look at peoples logs. Pre-facelift cars with the 6-speed dsg doesn't seem to have the throttle closure at high rpms neither.
The app will be updated in the future to have a fitting description instead of just showing "No Description Found".

Hi. Thanks for your info.
I am 7-DSG too.
You are using 93 octane fuel?
I will try your settings. My car has intercooler.downpipe.inlet. and I intake.
If you make more changes to your map, please share them.
It's not my car but yes it should be stock other than the JB4 of course.
New firmware online 27.01.2020 (60/86/5 - File Name JB4_EA888_8_6.hex): https://www.n54tech.com/forums/showthread.php?t=50428
Changes are as follows:
Refined part throttle driving
Change in spool up speed
Logging resolution increased

I know I'm talking to myself in this thread like a crazy person BUT there might be people lurking around which find my information useful nevertheless
So, I've been driving around with the new firmware for a couple of days now and I just have to said "Wow!". There's no doubt that the increased sample rate makes a major difference especially during part throttle. The JB4 is now so great all the time an not like 80% great part throttle and 100% great full throttle. The car feels more responsive and reacts better and faster to shifting during full throttle at 4-5.000rpm. I can't recommend this firmware update enough
The app has a new layout now (or at least mine has, maybe because I'm a beta iOS tester) and to update the firmware you have to go to above link and find the firmware at the bottom of the first post, click on it and download and then choose to open the downloaded file in the JB4 app. Then you can find the firmware in the app and choose to update from there.

I read your drivel Lehn... 
I updated a couple of days ago.
To be totally honest, I can't feel any difference.
I have never had any issues with idle, part throttle or full throttle, on any firmware since installing the JB4..
I get the ECU pulling the throttle at high revs in Maps 2, 3 and 4 now though..
As suggested by George, I assume it's the torque targeting. I do wonder if it's robbing us of possible power gains?!
I also have been getting a 3BEF code, which doesn't clear in the app. Something to do with boost pressure not attained.?!?
Doesn't affect the driving and no dash warning lights, so I'll just ignore for now.

Haha great! One reader at least
Placebo or not, as long as it feels better I'm happy
Regarding the ECU pulling the throttle, read my post here, second paragraph: https://www.audi-sport.net/xf/threads/jb4-info-and-discussion-thread.309046/page-9#post-3480724
Do you have a 4th gear log you could post here as csv-file or from Datazap? Then I can take a look at it and see if I can see something obvious that should be changed.

i got the new beta firmware update 2 weeks back and felt super smooth acceleration, however it seem it got slower as i have also measure 0-60mph thru dragy vbox. Do anyone feel slower than before after new beta firmware update?
Have you tried making a new log and compared to a previous log to see if it's the same boost? I know the boost is temperature dependant but you won't feel a 1.0 psi change as significantly slower as you're describing.

i saw the logs and compare it previous firmware logs, on map1 i m not able to reach 15psi + as its doing 12-13psi now although the temperature has gone warmer here. My A3 1.8tfsi stock boost is 9-10psi and FOL been set at 65
Hmm maybe they have tweaked map 1 little but normally they would say so then. You should try to write George an e-mail
Fitted a JB4 to my facelift S3 and noticed that when coming to a stop, it downshifts to first, but I can see the revs drop to around 600 rpm and the car feels like it's going to stall. Any one experienced this? I'm using Map 2
Just seen your post, I made a whole for my car and have a few AFR harness’s left over. If your interested pm me and I can show you some images and price.
have you got a video of this and Does it happen when you come to a stop very quickly ? Take off the box or put it in map 0 (Turns it off) and see if the problem goes away.
I ended up making one but sold it and my JB4 as I went for a Unicorn Self Tune

Fair enough, how are you finding the unicorn tune compared to the JB4 ? Is it a day/night differenceI ended up making one but sold it and my JB4 as I went for a Unicorn Self Tune

Never actually installed the JB4 as I couldn’t be bothered installing plug D and the OBD lead!
The Unicorn tune is Stage 1 and listed as 360+ on their website. I’ve an R600 intake, hose, muffler delete and turbo elbow so maybe get a couple of BHP from that.
Pulls really well and feels much sharper than stock. Very impressed for £499. Additional maps are £49

I haven't got a video, I changed the map to Map 4 just before and the problem has gone. I'm going to test it again tomorrow in Map 2 and see if it comes back, but yes, it was doing it when stopping quickly, it felt like it was going to stall but the revs picked up just before it did.
It seems map 2 is a bit generic, I really need to get my Map 6 sorted!
Drop me a PM if you're still selling the AFR harness

I think that’s just the how the DSG boxes behave, but if your haven’t got any bolt on mods, running map 4 (Designed for 7speed boxes) with 99ron fuel would be pretty much maxing out the potential of the JB4 on a stock car.
You could run a map 6 if you wanted to improve lower end torque. If you want some help with a map 6 send george@burgertuning.com with a 3/4th gear log and he’ll advise you on a map 6.
I’ll pm regarding the AFR harness.
I'
Cheers, I'm running 99RON fuel, only thing I've run it on since I got it. Only mods I have are the "pikey R600", turbo elbow, silicone airbox to turbo hose and stock air filter. Seems to be better on Map 4, but I will get the logs for Map 6 and get the most out of it

Just go for map4 since you have an FL S3. Before George made map4 a thing my custom map6 was very very similar to this map. You can’t really push more than 6psi extra out of the turbo and less the closer you get to red line.
@alpesh26
Map 2 is not great for the facelifted S3 if you wanna do launches because it adds too much boost in the top end, that's why they made map 4 for our 7-speed gearbox.

Thanks Lehn, very useful! Yes, on Map 2 I was getting overboost and the car was coming up with drive faults when pushing it to the redline. I did a firmware update and that got better but, as you say, Map 4 is for the facelift so best to run that.
I've noticed the "stall" happening again even on map 4 (but not as bad as it was on Map 2), revs are dropping and the car shudders as if its about to stall but it doesn't. Did you have this?
That doesnt sound right at all. stock boost is about 15-16psi (lower in 1st: 12psi, and 2nd: between 13 to 14 psi)

Mine is A3 1.8tfsi, you are probably talking about S3 stock boost. Btw after updating firmware to new alpha firmware and now I can see boost reaching on 15-16psi on map 6.

Hi,
I’m getting rid of the JB4 and going for a ecu tune as my warranty has now finished and have a AFR wire connector for sale, just makes it’s easier to connect and disconnect into the AFR tap without damaging the wire by using the positap. Looking for £25 and can be sent out via 1st class signed for (UK)

SO this means I can Add a Downpipe and won't have a CEL? just like flashing to a stage 2?
