Burger Motorsport Development B9 S4
 

Proud to announce that we have received our development S4 and will soon start offering products to cover this model. In the three years we have started working on the VAG Group vehicles this is the 7th addition to the stable and will be developed concurrently with the new 400hp RS3 since the board technology used for our plug and play device will be shared on the cars since they both use new tech SENT protocol sensors. A lot of the work has been done over the past year on our RS3 370hp version which shares some of the tech.
For guys that are not familiar with us we have been developing BMW products since 2007 and consider ourselves market leaders in the field of advanced piggy back systems. In 2013 we entered the VW/Audi world with offerings that we have expanded over time. Our headquarters are in California USA but we also run a R&D facility in South Africa for Euro spec cars and through our vast dealer network make sure the products are compatible for all markets and fuels. Our site can be viewed at BMW Performance parts | BurgerTuning.com and our VAG brand related products here: VW JB1 and JB4 Tuners, Intakes and Accessories - BurgerTuning.com

came from bmws and used their n20/n55 jb4's

Sub'd. My previous car was a F36 with the N26 engine. Heard nothing but good things about your JB4's in the Bimmer community. Also, I'm located in California as well, if you need a test car...

Looks like things are picking up in the A4 side, looking forward to hearing updates on this. Probably won't do anything for a few thousand miles, but definitely interested in a non-ECU tune. I know in the B8/B8.5 community the Chipwerke was an alternative, but too many people complained about shifting problems with the unit, hoping this isn't the case in the B9.

We have been doing VAG group cars now for two and half years with a great portion of them being DSG/Steptronic. You can view the range here: VW JB1 and JB4 Tuners, Intakes and Accessories - BurgerTuning.com
To date we have not had issues with rough shifting and iron out the cause in the 1year we took to develop our first unit prior to release. The Chipwerke is quite a basic unit compared to our offering and it only connects to the two boost sensors limiting its capability.

Makes sense, connecting to the OBD port seems like it would give a more comprehensive solution compared to chipwerke. Being that a lot of the work is done with the RS3, how long do you think it will be until it becomes available, 3 months, 6 months?

It will be less than 6 months.

Great news!

Just checking in, any news or updates on the tune so far?

You can catch updates here: New 2018 AUDI S4 Development Car - N54Tech.com - Your Source for International Turbo BMW Racing Discussion
At this point we making a circuit board change to increase the fueling capability the final unit will require.

The VAG group cars are done in Pretoria. I am currently doing the RS3 unit here.
The S4 was done in California though as we could buy a car far quicker and cheaper on that side.

We have close to 20 beta testers now and things are going well. We got some small issues to sort out programming wise and if all is good will put the units on our site by month end.

Power??
 

how much power have the testers been putting down?
Just went on the burger Motorsport website to check it out and didn’t not see the tune for the s4.

Hi,

We haven't had anyone test on a dyno yet and the closest 4wd dyno to us is 100's of miles away. We have 40 testers out now so its only a matter of time before someone hits the dyno.
Its not on the site yet.

I have the JB4 installed and I haven't dyno'd, but it is a consistent .4 (4.4/4.5 to 3.9/4.0) seconds faster 0-60 and .5 (12.8./9 to 12.3/12.4) seconds better than stock in 1/4 mile. I assume it must be right around 400hp.

I assume this will also work on the S5 SB (B9), correct? thx

Correct.

When does it go on sale? :)

We nearly done testing with the unit. The last car we did is full bolt on a Hybrid turbo with meth and it seems in the current trim the unit can handle it.
We trying to pin point a random fault some users are getting ever two to three weeks. Once this is solved we will put the unit up on the site.

What?!?!

A vendor we work with has already done a turbo upgrade.
They will also be releasing a affordable intercooler and intake system and we working the methanol injection integration of the existing kit on our side.

I reckon a lot of owners have been underwhelmed by the S4 considering the previous model can run 10's with the right mods so its going to be quite a big market.

Considering I was coming from a Prius, I am far from underwhelmed....

I'm sorry if this has answered somewhere. I just have a quick question.
My BMW JB4 gets the steering wheel control for different map and settings. Will this have the similar options or just boost control?

The Audi communication works differently to the BMW so we cannot get steering commands to the JB4 without a addition circuit board making it cost prohibitive vs getting the Bluetooth module for the phone.

George:
What if I told you I was willing to pay a not-unreasonable, but still decent amount extra for steering wheel or physical button integration? I am very much not a fan of having to fumble with a phone while driving in any situation, but especially to change power modes in an already high-power car. There isn't even a good place to mount a phone in the S4.

An aftermarket physical button that I can velcro/3M-tape to the steering column or center console would be better than a phone app for mode-changing. I go on 4000 mile cross-country road trips in this car every year and the option of toggling to a detuned fuel-saving economy mode while I'm traversing Nebraska, to a fully tuned power mode as I'm entering the canyons, to bypass mode/stock tune for traffic and the daily grind is very interesting to me.

If the cost of adding a circuit board for *-button steering wheel integration is too high, what about the option of a rechargeable Bluetooth wireless button? It could have a multi-color battery and mode indicator light, and a microusb charger port.

At this stage we unfortunately have too much on our plate to do projects like that.

I think in theory having that option sounds really good. In fact, this is why I bought the bluetooth adapter and JB4 app. I thought I could easily switch maps anytime I wanted on-the-go. I bought a vent phone holder (bestrix), connect my phone and launch the app (which is awesome btw), and guess what - I've only changed the map one time in the hundred or so trips I've made, and the only reason for that was because I was on a road trip and could not access 93 octane gas.

If you want to drive 4000 mile cross-country, you can put drive mode in comfort and you won't see much boost regardless of the map. Even if you do, since you aren't asking for full throttle, the boost given won't be much higher than what the ECU is requesting, at least that's what I've noticed so far. In fact, I believe it helped improve gas consumption as I averaged 27.5mpg on this trip where I had previously made it at only about 25 mpg (averaging 85 mph!).

Having the phone app btw, is quite useful. The app itself can be setup to capture logs by pressing a start/stop button, OR by setting it to log automatically at full throttle (or X % of throttle), you can review the graphs on the app and click a button to email it to yourself. It also pulls codes in addition to showing live performance like RPM, AFR, boost, ECU boost, map setting (always shows 3 for me), fuel trims, IAT, ignition and much more than what you could ever hope to see in the dashboard.

One quick question, you going to ship these to California??

We have close on to 40 testers now and tuning wise the unit is good. Some cars are throwing a random temperature sensor error that we figuring out now. It comes on randomly after a few days of driving so it makes it harder to trouble shoot the issue. We have produced the units though so have plenty stock for when we release so there wont be a production delay so we can start rolling out as soon as this is solved.

What is to prevent the ECU from adapting (with time) to the changes presented by the piggyback unit and thus negating the performance boost?

The picture of the parameters the ECU sees are mostly stock so there is nothing it can adapt back. At all times the ECU is targeting its programmed torque target and will log like a stock car.

Will your product allow for the deletion of the cat inefficiency MIL/CEL owners have been receiving as a result of running a catless downpipe?
In the event one was really pushing the car on a track (while running a catless pipe), it would be nice to be made aware of other malfunctions via the MIL.

For the US market there wont be any support for that. The unit will be CARB approved eventually and the feature will be disabled for US market.

Got it, thanks.

What? lol. This coming from a 3-month forum veteran with 4 posts. Put your tin-foil hat back on. I'm only posting over here because BMS seems to be ignoring the Audizeen B9 S4 subforum.
