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.

It will be compatible to SQ5.

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

Alessandro 10-25-2017 07:22 AM

thanks for sharing :clap:

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

alexc93 10-25-2017 09:10 AM

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

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

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

Alessandro 10-30-2017 01:52 PM

thanks for sharing we need more boost :)

Congrats! Nice work! Glad you are working on audiís! Been a while since I have had a JB tune on a car. I used APR on last S4. Canít wait to see what you come up with for my S5!
Canít wait till this is finished.

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 11-08-2017 01:31 PM

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.

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.

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 11-13-2017 07:59 AM

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 11-25-2017 10:16 AM

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 11-25-2017 06:45 PM

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

jason427 11-30-2017 10:20 AM

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

Please hurry with the tune!

Jason

Terry @ BMS 11-30-2017 10:33 AM

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 12-01-2017 09:13 AM

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?

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 12-01-2017 02:51 PM

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.
