You're gonna get huge power out of this motor. I ran a RaceChip on my 13 A6 3.0T and made a huge amount of power with it. Probably 70+hp. Audi limits the boost with the ECU, the hardware from all versions are the same, so changing that allows it to make significantly more power. Obviously the 310hp versions will make more than the 335hp or 354hp versions, because they're starting lower and ending up at the same point.

Hello, i follow the thread.
i m from france, i buy an audi S4 B8,5 from 2014 ( facelift) S-tronic 7 ( dsg)
moteur CGWC on paper 333 hp and 440 nm vs 351 hp and 466 nm on dyno
feed with 98 ron
i m looking for jb4 and for awe exhaust with oem dp

with jb4 i have to put it on setting n 3 ? right ?
for controle technique ( sorry for english) they plug they computer on obd, so if jb4 obd is unplugged, car run like oem or i need to uninstall all the system before control technique ?

thanks you

On current firmware on the unit if you unplug the OBD it still adds 2psi. I am not sure what Controle Technique is but if its to remove it for diagnostic purposes there is no issue with that.
For 98Ron map 3 is recommended.

Thanks.
Controle technique = technic inspection to be sure véhicule is ok for drive.
And they plug they computer on obd for diagnostic and do at same time test for C02.

So BMS plugged in obd = map 3, i turn off the car, i unplug BMS from obd and get map 1, i go to technic inspection => no problemo ?

After inspection, i turn off the car, plug BMS in obd, map 3 get back ?

sorry for stupid question

Yes, this is possible. At idle and light load where most testing is done the emissions will not change at all and be in line.

Just took delivery of the JB4 yesterday, ready to take it for a spin.

I came from Racechip, hoping JB4 would give me better drivability.



George, could you please explain what every map's functions are?

newbie here, sorry if I have a lot of questions.

I have a smaller SC pulley that can produce 14 psi of boost.

Also installed AEM's WMI, 50/50. Only using it for cooling and some safety in the Texas heat for now. Not tuned yet to take full advantage of it.

I'm trying to make JB4 transparent below 3000 rpm so daily cruising stays stock. Then produce max boost from 3500 rpm to redline.

I find the stock fuel trim super rich, is there a way to trim fuel using fuel bias? Not sure if this is something adjustable on this platform.

thank you.

Hi,

The best bet with this is to send logs in map 1 to start and we can work it up together. I haven't worked with a car that has a pulley mod. We can attend to the fueling then as well if needed. Email logs to george@burgertuning.com

Thanks for the quick response! I just emailed you the log file. Appreciate your help.

Is there a installation guide for this engine in an A6 (c7)?

[Mike_L]

Does this install on the MAPs? If it does I have a pic for you that I took 7 years ago to show the install of a Racechip. Very clearly shows the locations.

[Terry @ BMS]

Yes attaches to the MAP sensors on the manifold, and OBDII. George should have a guide for you,try emailing him?

[Mike_L]

I haven’t seen the guide, but this may help some people.
