Burger Tuning JB4 Golf 1.8TSI MQB specific information thread

So I ran a log on Map 4. Trims, AFR, and Ign1 all look much better.

I emailed George about it and he said they had a firmware update that will correct the issue I was having, which he attached.

So the next step is to update the firmware, run another log on Map 2, and look for improvements.....stay tuned.

Cool, looking forward to seeing this fixed! Thanks for the update. Sounds like the firmware update may be released soon since you were able to get hold of it that easily.

I did some more logging tonight with the updated firmware...

45 degrees F, 93 octane fuel. About 5-10 minutes between logs. I'm noticing that my car is having a hard time putting out the target boost above 5300rpm.

First log is on Map 1. I think AFR, Trims, and Ign1 all look pretty good, no?

https://datazap.me/u/stuntnuts/log-1507856977?log=0&data=1-4-11-14-18

The second log is on Map 2. AFR looks good, Trims look decent, Ign1 has a couple of craters in it. Again, can't keep up with target boost above 5300rpm.

The third log is a bit scary. Also on Map 2. AFR is has a couple of decent spikes in it. Trims have quite a spread. Ign1 spreads between 1 and 14.5. Is that dangerous? I don't understand Ign1. And again, tough time keeping up with targeted boost.

https://datazap.me/u/stuntnuts/log-1507857270?log=0&data=1-4-11-14-18

So I'd say the firmware update helped AFR, but Trims and Ign1 are still all over the place. This seems much more pronounced on Map 2 than on Map 1.

I'm in contact with George, but if anyone has any input on this mess, I'd love to hear from you.

I really want to get this sorted out so I can feel comfortable installing my IS20.

That looks awful. AFR is going the wrong direction and it can't even hit target in map1 after 5k.

Your AFR looks awful on all of them after 5k. What is the AFR bias set at?

 

[TwinDad]

What firmware update? I didn't know they released one yet for the JB4

UGH, I'm going to throw up.

Fuel Bias is at 100.

They didn't release it yet, they are still tweaking it. George sent it to me to try, in response to my spiky AFR that I posted in this thread a few days ago.

What happens if you run absolute instead of additive? Try these settings:

Just for shits and giggles.

Diggs, that link you just posted is just logs, no settings.

Pretty easy to decipher, just look at target

I see:
1500 probably 12
2000 14
2500 15
3000 16
3500 16
4000 16
4500 15.5
5000 15
6000 14
6500 13.5
7000 uhhh 12.5

Oh, I follow now. Thank you

What should I set FOL to with these settings?

 

[Diggs24]

If you want to play it safe knock 1psi off everything 4500 up

This is really a great thread and George has been helping me out with tweaking the settings too. On the side note, has anyone tried to measure 0 to 60 time of 1.8TSI with Jb4 Map1 + stock internals?

Leave FOL where it is.

Given that we're all fwd we tend to ignore 0-60 . I measured a ~6.27s with APR stage 1 with an excellent launch, but Map 1 is pretty conservative so that would be pretty hard to match. Theoretically if I was able to actually consistently launch my car I should be in the mid 5's right now, but to me the more interesting number is 60-100 which my best is 6s flat. I think most people with conservative jb4 maps are in the low 9's to high 8's from 60-100.
