Use subject to terms and conditions posted at http://www.burgertuning.com/terms.html

Order here: http://www.burgertuning.com/vw_volks...Jb4_tuner.html

THIS PART IS LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND IS NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a "racing vehicle" as "a competition vehicle not used on public highways." (Calif. Health & Safety Code 39048) This part may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THIS PART IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BURGER MOTORSPORTS, INC, AND CAN VOID YOUR VEHICLE'S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of this part, and Burger Motorsports, Inc hereby disclaims any liability resulting from the failure to use this part in compliance with all applicable federal and state laws.


We'll use this thread for our upcoming Audi RS3 & TTRS JB4 SENT BETA updates, map guides, firmware, and discussion!


Install Guide here: http://www.n54tech.com/flash_files/audi_s4_install.pdf

Optional map changing, datalogging and updates are done using the BMS data cable or JB4 Mobile REV3 bluetooth kit.

JB4 Mobile Smart Phone wireless connection directions Click here
BMS data cable hard wired directions and software Click here


Map guide as of v4 firmware:

Map0: Stock tuning, disable JB4
Map1: (default map) 2psi peak over stock
Map2: 3psi peak over stock
Map3: 4psi peak over stock
Map4: 5psi peak over stock
map5: 6psi peak over stock
Map7: Integrated WMI (water/meth) map, progressive control with boost increased as a function of fluid flow up to the user defined WMI additive.
Map8: Valet/Low Boost/Safety map. Runs 25% less boost than stock.

Dragy results:
10.8s all stock on JB4+E30: N54Tech.com - International Turbo Racing Discussion - View Single Post - JB4 for 2018+ AUDI RS3 TTRS


Firmware:

JB4_AUDI_TTRS_5:

1) Adjusted map5 to target up to 7.5psi over stock, for those running E30 or unleaded race gas who want to push things a bit. Results in around 22psi in most situations.
2) Adjusted shift boost reduction logic to further reduce boost spikes during shifts. Default setting is shift reduction = 50. A higher value will reduce boost more during shifts and a lower value less.
3) Minor adjustments to boost ramp in to improve operation under boost limiting/loss of traction situations.
4) Added support for low fuel pressure hardwire connection to monitor and rescale, allowing some fuel trim reduction in heavy E85 mixtures. Requires harness addition so is just under testing for specific cars for now.

JB4_AUDI_TTRS_4_T3:

1) Various minor map and tuning revisions.


JB4_AUDI_TTRS_3:

1) Revised boost targets per map
2) Added direct boost control logic allowing dramatically more boost than is possible previously. Enabling this unique feature requires purchasing the optional BCM module.
3) Revised logging channels to include high fuel pressure on a scale of 0-50 = 0-3000psi.
4) Revised logging channels to add road speed
5) Added in over boost and lean-run JB4 safety systems. If boost exceeds user adjustable "boost safety" setting for more than 1 second the JB4 will switch to map0 (disabled). If AFR goes leaner than 15:1 at full throttle for more than 1 second the JB4 will switch to map0 (disabled). More advanced user adjustable safety systems including the ability to failsafe to less boost than stock (for flashed cars) is under development.


JB4_SENT_AUDI_RS3_1:

1) Adjusted warm up temperature safety to avoid bug with it kicking in when car is heated up.
2) Adjusted cyl 2-5 logging parameters so they show much higher values, to make boost/octane evaluations easier.
3) Created a firmware split so "S4" firmware will be used for all six cylinder models, and "RS3" firmware for all five cylinder models.

FutureUseD Bit Settings as of v3 firmware:

Bit0:
Bit1:
Bit2:
Bit3:
Bit4: Turn on to disable JB4 passive safety systems (over boost safety, lean run safety)
Bit5: Turn on to disable extended Audi logging channels (knock 2-5, dme bt, ecu_psi, fp_h, gear). Disabling these channels doubles the sampling speed of the primary channels.
Bit6:
Bit7:

Here is a log off a flashed one, who will be using the JB4 for fine tuning, logging, and running WMI. All of the JB4 maps are currently additive based. So he's adding a couple PSI over "stock" here.

AFR seems pretty good on this engine platform. What's the highest E85 mixture we can run with JB4 only?

Still a work in progress on the RS3, need to get fuel control working. We have it active on the S4.

What about 1-2 gallons per tank, for now? Our 91 is so bad here.

Should be fine, knowing you, we'll get logs both ways.

On the RS3 the big things we need to get done to really be competitive with the flash tuners:

1) Fuel control active
2) Wastegate control active

Of course, the flash tuners can never compete with the JB4's ability to remove the tuner without a trace.

Awesome. Launch control is so bad ass with this car. I could never launch this hard with my B58, even with launch control and sticky tires. Even with our 91, this thing just pulls all the way through 3rd gear.

I'm "supposed to be" breaking the engine and clutch in, ha ha. Did one launch control before I made the purchase just to be sure I wanted the car. Only had 100 miles at that point. Boy was it worth it.

The S4 launches really well, it's a standard style automatic transmission which I prefer. Easy 1.80 60' times. Would be faster with more power. It just needs a bigger turbo to compete with the RS3/TTRS crowd.

I'm not really understanding the transmission and shift behavior on the car yet. When driving normally on city streets it upshifts very quickly from 1st to 2nd, but then hold 2nd very long, as well as the next couple gears. I'm using Dynamic mode only for now to vary the RPM's and break in the car. Also, the damn shifter is backwards for up and down shifts. Hopefully there is some flashing that can correct these annoyances.

What tune is the other customer running? Integrated Engineering looks legit. Obviously APR is well known. But they are owned by the same company as Dinan!

Default Jb4 ?? - 12-15-2018, 02:56 AM

I have some newbie questions about the jb4 scene, just want to make sure Iím not misunderstanding anything.

I was looking at the other rs3 thread which said there were still issues being sorted for the Rs3 before it becomes available. Can I assume that this thread here implies the issues have been sorted and it is now on sale?

Also from what I read the jb4 unit is the same hardware for s4 and RS3, hence why all the documentation refers to S4?

I am confused about the order link as it makes no mention of Rs3. If you order on the supplied link how do you specify the RS3 code.?

Lastly are there any instal pics which show where the sensor connectors are located under the bonnet.

Look forward to your advice.

RS3 uses the same JB4 as B9 S4 and that is what you can purchase at the moment.

You need to update the JB4 with RS3 hex that is 1st post. You will only be using the TMAP and MAP connections on the harness for now.

More features will be added soon and a proper harness will be released in the near future.
I just got my JB4. I'm anxious and want to play.

Our development TTRS finally arrived! Wasted no time throwing on the JB4 BETA to data log some stock runs (JB4 map), install was super easy. Photos below.

Is that with stock tuning or with the JB4 adding boost? Either way, you have some catch up work to do with me

Currently 100% stock with APR's Stage 1 E85 flash.

All stock baseline! See attached JB4 log from run.

We have a couple objectives with the platform. First to provide a robust tuning system for those who don't want to void the warranty by flashing. Second, to provide those who have taken the plunge to flash tons of extra features and options to make their tuning easier to use, safer, and more intuitive.

Yeah, these cars rip in stock form. E85 allows well over 20 degrees of timing at 22 PSI. Looking forward to stacking with the JB4 on lower ethanol mixes and less timing.

I've been running the beta since December on my RS3. I've been communicating with George and sending him logs. I get an occasional random throttle close when WOT. Not sure what is causing it but seems like I only get it in the early morning when it's cold.
