WMI might be a good option, we haven't had a chance to start that development yet.

For starters just run map1 or map2 and log so we can evaluate it.

Hi Terry,

If you could get a box to me over in the uk before the 3rd of May as I said Iím going on a Road Trip around Europe visiting the tracks at Spa, Nurburgring, and down to Monza so Iím more than happy to Beta test for you!
Will be Running 98ron fuel although 102Ron is available in Germany so it would be interesting to see how the unit performs, combined with my straight pipe exhaust and cold air induction kit!

Genuine offer to test my friend.

Appreciate the interest but prefer test customers closer to the USA for the moment.

Ok mate no problem ;)

I assume you probably have plenty of test vehicles, but I have a SQ5 and would be willing to test, and also happy to wait until a product launch as well :)

We have a SQ5 tester but a second one wont do any harm. Drop me a email George@burgertuning.com

It would make sense that the boost is being stepped at lower gears because of the lower speeds -> less intercooler airflow. That aligns with the weak intercooler performance that was observed in the testing.

I want to see if anyone else has a take on the intercooler before jumping on IE's offering.

Terry @ BMS 04-19-2018 04:02 PM

It's more about rising intake temps causing a higher boost target so power can be kept level (from the factory tune perspective). On the IC we'll be making one. Don't have an ETA but we've started on it. :)

nvm, saw above post

If you are still looking for testers I've got a stock S5 Sportback.

Hey George...any updates on RS3 dyno testing with your beta JB4 setup?

Here is a dyno on 93oct on a otherwise stock car. Power was measured at the front wheels on a generic map that doesn't target high torque. We still got a bit of work to do and will be putting updates as soon as we have something new.

Thx George... looks like some good numbers so far. Im a little surprised the stock run is showing so little parasitic loss. Loosing only roughly 25hp due to driveline/etc(would expect something close to a 60 hp hit/loss)...? If correct I guess this suggests your initial tuning is pushing the stock 400hp number to around 460ish?

thx....

I reckon around there.

Have you guys gotten an S4 on the rollers yet?

Chavoos 07-13-2018 10:03 AM

George and Terry

Having used the JB in the N54 and N55. I am a big fan.
I will be getting an RS3 and watching very closely.
Will history of the tune be visible when the JB is removed.

Nope, same as all our products. Clear codes, pull Jb4.

Maza454 07-17-2018 04:10 PM

Hope JB4 should be ready soon for the RS3...

Its being worked on. Once the S4 unit is released the RS3 will follow a few weeks later.

txdp123 07-20-2018 08:46 PM

Curious, but would the JB4 for the S4 work on the new S5 Sportback (Same Engine)?

Yes, it is compatible to the S5 as well as the SQ5. We have quite a few testers using them on both.

Hey all! Can't wait for the JB4 for my S4. Have all the little hiccups been found and fixed? Can't wait to test it and make a record with our 94 pump fuel here. Then try Ethanol blends :burnrubber:

Thanks!

Alex.

Terry @ BMS 07-30-2018 09:06 AM

It's taking forever to sort out this minor IAT sensor bug, since I'm only able to trigger the fault every few days. But we're closing in on it. Once resolved we've got the systems ready for wide release, for the S4. Then we'll get to work on the RS3.

I love the way the TTRS looks!

Chavoos 07-31-2018 06:28 PM

Test in South Africa
 
Hi George

Long time no hear.
Good to see JB4 work on the RS3
If you need any more test vehicles , i may be keen.
