We'll use this thread for our upcoming B9 Audi S4 SENT JB4 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.

Map guide as of v4 firmware:

Map0: Stock tuning, disable JB4
Map1: 2psi peak over stock (default) 91oct
Map2: 3psi peak over stock 91oct
Map3: 4psi peak over stock 93oct
Map4: 6psi peak over stock, E85 mixture, race gas, or octane booster suggested
Map5: 6.5psi peak over stock, E85 mixture, race gas, or octane booster suggested
Map6: Custom tuning map, can be used as additive by setting RPM1500 less than 5psi, or absolute by setting it greater than 5psi.
Map7: Water/Meth (WMI) Progressive Mapping
Map8: Low Boost/VALET map. Runs 30% less boost than stock.

Firmware:

JB4_AUDI_S4_4_T4:

1) Revised maps per above. Changed map4 to performance map, adjusted map5 target, changed map7 to WMI map, changed map8 to VALET/low boost map.
2) Logical revision to correct 233F false alarm fault code some got when letting off the gas.
3) Tuning change to improve boost performance on tip in.
4) Added support for BCM (boost control module)
5) Added support for map6 to be used as an absolute target map in conjunction with the BCM, we expect this will be useful for those running larger turbos. When using map6 the boost value entered under "RPM1500" determines the profile. A value of 5psi or less makes map6 an "additive" map meaning the value is added to the stock boost level. A value of map5 or more makes map6 an "absolute" meaning the JB4 targets that specific boost value. The logic does not yet allow for targeting of less than factory boost levels so if you enter an absolute target below the stock target you'll receive the stock target.

JB4_SENT_AUDI_S4_2:

1) Adjusted warm up temperature safety to avoid bug with it kicking in when car is heated up.
2) Added cyl6 knock correction logging. Adjusted cyl 2-6 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.


AUDI_JB4_SENT_T7:

1) Adjustments for WMI integration.
2) Potential fix for bug that lights off every code in dash when letting off gas suddenly on higher boost maps.

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.

[Payam @ BMS]

Great looking car with lots of potential!

[135idct]

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

[Alessandro]

Nice finally first dibs if you need any beta testers

Cant wait

[A418t81]

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

[Terry @ BMS]

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

I'll let you know in a couple weeks.

[jomama]

subscribed to see what awesomeness comes out of this!

[Sticky]

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

[Mike_L]

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.

[Terry @ BMS]

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

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.

[Sticky]

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

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]

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

[Alessandro]

Terry any progress you can share?

[Terry @ BMS]

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]

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]

How do you engage LC?

[Alessandro]

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]

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.

[Terry @ BMS]

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

[Alessandro]

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]

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.

[Alessandro]

It went from 107 to 111 best time was with the 109 trap

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]

Most likely yes but check with George on that.

[George @ BMS]

It will be compatible to SQ5.

[alexc93]

It will be compatible to SQ5.

[Terry @ BMS]

First tuned log off an S4... Around 2psi over stock. So far, so good.

[Alessandro]

thanks for sharing

how much boost is it running stock is it like 18 psi?

[alexc93]

Following intently...so exciting to see you guys on the audi platform after many years with you on the bimmers

[Terry @ BMS]

thanks for sharing

how much boost is it running stock is it like 18 psi?

Yes around that, I'll post a stock log later.

[Terry @ BMS]

Little more testing from last night. Nice 1/4 mile gains at 2-3psi over stock.

[Alessandro]

thanks for sharing we need more boost

[jason427]

Congrats! Nice work! Glad you are working on audi’s! Been a while since I have had a JB tune on a car. I used APR on last S4. Can’t wait to see what you come up with for my S5!
Can’t wait till this is finished.

[Payam @ BMS]

Man the IAT goes up so much in just one pull!

[jomama]

Man the IAT goes up so much in just one pull!

so maybe some combination of a larger intercooler, meth and e85 will help release some fury?

[IanCH]

There is an intercooler on ECS that supposedly fits our cars. Dont know if it actually does.

Also, hello everyone, really looking forward to this product release! will be an early adopter for sure.

it allegedly fits both a4 and s4 cars, so it seems a bit suspect. at least the plumbing has to be different.

https://www.ecstuning.com/b-integrat...t/ietpck1~int/

Yeah, it had me very skeptical as well. It seems like if the intercooler was universal fit that there would be many more than the one.

[George @ BMS]

https://www.ecstuning.com/b-integrat...t/ietpck1~int/

Visually on the tech documents the two coolers look the same. I reckon the size remained the same for lag reduction.
What is even more interesting is the Twin Turbo RS4/5 got a charge cooler instead.

[IanCH]

So, what do I need to do to be a tester for this JB4? I'm technically savvy and have a S5 SB :D

sorry, I'm just being impatient, the car can do some fun stuff now but with a little more power its gonna be a blast!

[Terry @ BMS]

We finalized the harness and new JB4 board for it, so now it's just a waiting game for early production parts to show up. Then we'll start looking for willing testers.

We've got the S4 here and George has the RS3 with him so between us we've got the new SENT sensor well covered for development.

[Alessandro]

Terry, i am waiting on to test those let me know once available.

[jason427]

I'm dying here... This car sounds amazing but can't move out fast enough.

Please hurry with the tune!

Jason

[Terry @ BMS]

Haha we're working! Turns out fuel control requires a SENT channel so we had to add another one to our new board. 3x SENT channels now.

It's been slow going waiting for parts to come in since it's a whole new board and electrical changes we make result in a 2 week delay waiting for fabrication.

so is there hope for anything more than nominal gains? i know it was mentioned earlier that the rise in IAT after a couple pulls may be a problem, and that you weren't sure how much room there is for improvement.

[jason427]

I am wondering the same as above. I hope I didn't make a mistake going S5 route over the RS3. I like the S5 but not at stock power level. It's gotta be able to dip into the 11's or better I will get bored too with it.

I'm not sure yet what the tuning potential is on the platform. It's a little too early to tell. I'd guess its going to wind up in the +50whp on pump gas, +80whp on E85 mixtures area, when its all said and done, but we'll have to see. So probably looking at high 11s otherwise stock really pushing it?

Jason

i think we made a mistake currently also driving the S5 SB and fore sure there is not way we can reach the power levels of the new RS3.

Well mine is a lease will see what happens next.

[jason427]

That's a bummer. I was stoked to hear twin turbo 6cy thinking it was going to be a beast after tuning... Oh well...
I may have to switch out sooner than later if it doesn't go low 12's - high 11's.
