Hey george did I read somewhere that you are currently working on being able to tap into the second set of injectors with the jb4?

At this point we are working on the low pressure side to add more fuel. We havent done work on secondary yet or at the moment seen a need since it seems supply from the back is the primary challenge.

Thats interesting, it seems all the flashes utilize the port injection to get full e85 available while running the stock LPFP

Yes once you flash you have a little more headroom on the fuel trims side. But run in to limitations on the fuel pump and fuel injectors shortly after. For those who want to run straight E85 you're going to have to bite the bullet and flash the car. And once you do can still use the JB4 on top of that for fine tuning, boost by gear, logging to your smart phone, etc, etc.

Hey Terry,

You going to develop intake or any bolt on for the rs3/ttrs platform? They can use a dsg breather and maybe a catch can too. Just seems kinda stagnant compared to your other platforms.

Not much of a market for the RS platform based on how many cars are produced and the fact that there's already multiple offerings out there. There's a lot more R&D for making hard parts. I could see breathers or catch cans, though. Give it time.

I suppose that has some merit. Under 3000 rs3 from 2017-2019 and ttrs even less. Though there are some low hanging fruit there for parts for sure.

Testing a DSG breather/catch can system now. Trying to get the right design to keep it simple to install/remove and still effective. Will share details when ready.

As to the intake would be cheap/easy to do but I think that market is already well saturated? What is the cheapest intake out?

We will have an IC option using the same core we're developing for the B9 S4 and Kia Stinger.

Most intakes are ridiculously expensive because they are made with carbon fiber.
I think CTS makes the cheapest intake.
I'm running a Forge motorsport 3.5" inlet hard pipe with K&N panel filter. It works for me...keeps things quiet.

Keep in mind the the 2019 models have changes on the DV hose.

Hi
Has Anyone experienced a knocking sound/inconsistent idle after driving their RS3 a bit hard. I experienced this on MAP1, oil temp was around 104įC. Once I put it into MAP0 and temps lowered, it seems to have disappeared. Also, randomly under acceleration, the car seems to lose boost completely in 3rd gear. My car only has a BMC filter and runs on 93 unleaded. The JB4 read 2 codes (P0804 and P01302), not sure what these are. Any help would be greatly appreciated!

Thanks!

The JB4 monitors knock in all cylinders, post up a log so we can check it out! On the faults if you clear all codes ign on, engine off (sometimes takes a couple times to clear), when do they come back?

Hi all,

same problems here with the boost sometimes, which user"theskunk" reports.

Pull the Pedal , no Boost. Then get off an pull again, geos off like hell.

Only Pipercross plate filter and PPH Air Pipe 90.

Runs with 102 Oktan. JB4 with BCM and v4 Firmware.

Happened in all Maps. Exampel in Map 6 + 6 psi

Results enclosed.

Is there any new Firmware in progress ?

Greetings

We working on resolving it. Our car rarely does it which makes it a bit harder to pin point but its on our priority list.

I havenít been able to recreate the issue, it seems that shifting a bit early into 3rd causes the loss in boost. Been running Map4 on 102 octane (BMC filter is the only hardware) and havenít experienced the same issue, only happened in map 1/2 on 93 octane.

There are times when the ECU limits throttle to ~65%. Other times the car will start to build boost then the ECU suddenly cuts throttle to ~30%.

Usually if you let up then go WOT again and it's fine. Occasionally the car won't go no matter how many times I try letting up.

I was having it about once a lap on an open track day at VIR on Monday. Ultimately, I decided to disconnect the JB4 until an update comes along to resolve this. If additional logs are useful, I’m happy to reconnect.

Just traded my 18 R for a 2019 RS3, canít wait to get a JB4 on it. However, this intermittent loss of boost issue is making me wary. I just want something that works, every time. Probably stay stock until they manage to figure it out.

Given the intermittent nature and the fact that the issue comes up on the RS3/TTRS but not the B9 S4 that uses the same hardware, it's been really tricky to pin down. We're testing a circuit board change right now to see if that has any effect on it.

Honestly, it's not THAT big of a deal. The BMW B58 headaches were much worse. While annoying at times, it's so worth it to have the JB4 for logging and additional safeties.

Don't worry, Terry will figure it out and will be a simple firmware or board change. JB4 for life!

I hope a board swap isn't required...getting a JB4 shipped to me is already kind of a pain.

Maybe if it was $200 sure. But I don't like the idea of paying money for 1/2 mile events, 1/4 mile events, just to have it potentially cut out and not work properly.

If its just for logging then it needs to be a lot cheaper.

Additional safeties are great but not when it introduces a no boost scenario randomly.

I'm coming from N54 and am a big proponent for jb4 on that platform. But this is reminding me of my 4bar issues and I am not gonna go down a road like that again.

Lol, proper logging tools cost more than just $200. They also don't have any safeties implemented either.

The 4bar issue never had anything to do with the JB4, it was the sensor itself.
Just want to clear that up...

Hey Payam, lets keep it professional. Like I said I am a JB4 proponent.

I can find tools for logging many other brands for $200. Hell you can take MHD and use it for just logging. My point must have gotten missed. If I am paying full price for JB4, I personally expect it to perform to the same standards as it does on other platforms.

The 4bar issue was not JB4 and you guys were amazing in replacing it 3 times for me. I am referring to it since it was an unsolvable (at least for me) issue for 2yrs, 3 sensors, multiple firmware or parameter adjustments, and it would pop up randomly and cause issues. That type of experience is not something I will be bringing with me to the RS3 platform. The 2.5tfsi is known for its repeatable performance. Not misfire/issue city the N54 has.

Maybe but the 2.5L engines pop often so don't undervalue the potential JB4 safety benefits especially if already flashed. A new engine starts at $15k+.

Also FWIW for the TTRS/RS3 there are not good logging tools that record knock in cyl2-5 real time to your phone. There is just the VagCom cable system which is a huge headache to use and has slow sample rates.

You'll have to decide what makes the most sense for your build. Our development TTRS has been tearing it up running 10.8 1/4 mile times JB4 only on 30% E85 literally problem free. I think only one time in the last six months have I had an aborted run due to low boost.
