Hey guys,

We'll use this thread for our upcoming Audi S4 & RS3 SENT JB4 BETA updates, map guides, firmware, etc. Stay tuned for more updates!


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 3rd party JB4 Mobile REV3 bluetooth kit.

JB4 Interface: Latest Interface Download.

If you need directions on how to connect a laptop to your JB4 to update firmware or how to datalog Click here.

JB4 Mobile and IOS interface posted here: http://www.n54tech.com/forums/showthread.php?t=21742


Map guide:

Map0: Disables JB4 all together
Map1: (default map) 2psi peak over stock
Map2: 3psi peak over stock
Map3: 4psi peak over stock
Map4: Stock tuning with CANbus active for logging
Map5: Open
Map6: Open
Map7: Open
Map8: Open

Firmware:

AUDI_JB4_SENT_T6:

1) Added map5 which is 6psi peak over stock, for race gas and E85 mixture experimentation
2) Added knock monitoring in cyl5. Will add cyl6 shortly.
3) Added flash boost target logging
4) Changes to avoid triggering 9023 manifold pressure too low fault when letting off the gas on higher boost maps

Be interesting to see what this kind of turbo can do.

Great looking car with lots of potential!

135idct 09-27-2017 02:09 AM

Nice car,
i think it will be like the B5 s4 in tuning potential :burnrubber:
baseline number?

Alessandro 09-27-2017 02:19 PM

Nice finally first dibs if you need any beta testers

Cant wait

Do the new SENT sensors make manipulation a lot more difficult?

I'll let you know in a couple weeks. :)

jomama 09-28-2017 09:54 PM

subscribed to see what awesomeness comes out of this!

Sticky 10-05-2017 06:45 AM

And you can't develop for a 911? For @#$ks sake Terry...

911 production is a small fraction of cars using the 3.0T. There has to be a business case to support a vehicle/motor.

Once we get it working for the S4 then I suspect the same hardware will work on the SENT sensor 911s. :) So we can talk then.

A larger % of 911 owners will modify and this will apply to the 991.2 Turbo as well as the Boxster/Cayman.

Bigger market than you think but we'll see what happens.

casterson 10-08-2017 01:00 AM

Woah, that is a really nice looking car! Do you have any front pics as well, please? :D

Alessandro 10-13-2017 02:13 PM

Terry any progress you can share?

Making good progress... Have SENT mostly working, and CANbus mostly active.

Also testing out a new really affordable GPS performance meter called dragy we'll be distributing soon. Results of a stock run I took earlier today on 91 octane... Slower than expected. I'll try again when its cooler out with a harder launch.

Alessandro 10-16-2017 06:45 AM

Terry thanks for the update, what i noticed during my first runs is you need to launch it very hard with LC otherwise the car will not get out of the gates very well.

Best i could do stock is 12.6 at a 109 80 DA 1400.

Terry @ BMS 10-16-2017 07:57 AM

How do you engage LC?

Alessandro 10-16-2017 08:01 AM

its not a proper LC but you need to be in Dynamic Traction Control off hold the brake firmly apply gas, RPM goes up to 4K i believe. Its like brake boosting but it does launch the car much harder was able to get 1.69 60ft.

Terry @ BMS 10-16-2017 02:19 PM

Oh, yes I've tried that. Got RPM up to like 3000rpm... Was a bit quicker with a 1.9 60'. Will try again when its cooler out and post the results.

Almost ready to get started on tuning it! So I'll need a good baseline for that.

Updated times stock on 91 octane, brake boosting it harder.

Alessandro 10-21-2017 06:53 AM

Just a short update.

Came back from the strip and best time with a tuning box currently available on the market was 12.2 on various settings vs. 12.6 stock similar weather conditions same fuel.

I thought i try something else on the market available to shorten the time for terrys product. Still waiting inpatient for the JB5 :).

I will not disclose the name of the tune here in the forum for obvious reasons. Time slip and video will be posted this afternoon.

Terry @ BMS 10-21-2017 08:56 AM

Glad to hear there is at least some tuning potential for them! How did MPH change? We've got logging up and running and the car is running quite a bit of boost from the factory. More than I expected.

Product we're developing for the S4 will be called JB4. It's a new JB4 board that also has SENT capability along with CANbus and the rest of everything you've come to love about the JB4 over the years.

Hi Terry

Will this also be compatible with the B9 SQ5?

Same motor as the S4 so assume it will be but figured i'd ask to be sure... picking one up in the next few months.

Terry @ BMS 10-23-2017 01:10 PM

Most likely yes but check with George on that.
