Looks like something fueling related for sure, usually would be trims maxing out but they aren't maxing out in the log. What happens with 1st gear set to say 3psi?

Thx for helping me diagnosis this. I will have to retry to see what it does in 1st gear by adding boost +1psi each pull...then I can get back to you.

I personally am not clicking a random link when the .csv can be uploaded directly. Risky business.

[Syeghyayan]

Did I attach it correctly

[Serstylz2]

Yep solid logs.. the log pros should be here soon

[ddnspider]

Something really funky going on in those logs. I've seen targets of 6, but boost is also 6 like its not commanding any boost. Seems like a setting issue or something isn't connected correctly.

@ddnspider
what do you recommend that I should do? What is funky about it? What is it I should be looking for here to fix my problem?

[ddnspider]

Review the settings on page 1. Make a pull on map 0. make a pull on map 1. Then it can be compared. Safely, try to get a couple gear wide open throttle run.

Yep definitely something wrong with my jb4 not doing anything for me highest psi is at 10psi ... like its restricted or something

[Peekb24]

Has any with an RS noticed boost spikes with bit6 turned on ??? Terry@bms

Seems like something is wrong as boost is so low, log on map0? What codes are coming up?

Looks pretty normal to me.

If you need technical support rather than just general log advice, you'll need to email in, unless you're not in a hurry. I'm not always to stay up to date on this thread.

Highly likely your map sensor connectors with the JB4 are not seated properly or you have bent pins or a poor connection. This would entirely explain the lack of boost from the logs.

[Syeghyayan]

What should I do in this case ? I’ve tried unplugging and plugging make sure pins are aligned at this point I have no idea it’s been this way for about 3 months I even noticed the power loss

[ddnspider]

I would contact BMS about troubleshooting and possibly a replacement.

[Syeghyayan]

Thanks you all for help and support

Hey new to the thread
Just got my jb4 on a Stock Q60 red sport And would like to have log reviewed to see if all is good

Your timing dropped significantly in third gear, 4600RPM as boost hit 17+ PSI. You may need to back it down to +2 or 3. Best way to evaluate the log is a longer pull say 2nd to redline and then 3rd up to 6500 or so. Timing is Ign1. You shouldn't see sudden large drops in the number except at gear change. What Octane fuel were you running?

Hey thanks for the reply
Right now I’m running 91 but will be switching to 94 next fuel up

[JCB]

94 octane will make a big difference. Take it easy for now on the 91...car looks like it is fighting knock. Did your JB4 come with the fuel wires? If so hook those up. Also highly recommend the wastegate control wires.
