Here is the log in which you see everything.
In 3rd trims is ok and from 4th on you see it is stuck. AFR is too high for my taste.

Dumb question. but is your afr/fuel bias set to 100 at all the rpms?

Hey Diggs, I can see they are set at 100 from looking at the log file.

Tip for those that don't know...from the datazap website when viewing the log, go to the bottom right (below the graph) and download the CSV file. Then, open the CSV in Excel, Google Sheets etc. and you can see the JB4 settings the log was run against in the first two rows of the log file.

Yes that is correct. So if someone has a solution for flatline trims...
Nevertheless I ordered GTI injectors for trials.

See if you can return them. The Golf R shouldn't be that much more. I got mine for $270 shipped from a german ebay seller.

I still had the log window open when I turned on my PC this morning and I noticed (in your CSV log header) that your FOL set at 90. Was this done on purpose or by recommendation by someone? Typically FOL is set between 50-70 for GTI's and Golfs's here in North America, but it does depend on other mods/settings etc. For a typical JB4 setup, Golf 1.8's are usually set on the higher end (60-70) and GTI's on the lower end (50-60). If it is set too high, the higher fuel pressure the JB4 requests can cause the fuel pump(s) to not keep up with demand.

I think your best bet is to work with George @BMS to help troubleshoot this particular 1.8t variant used in your Skoda. Many ROW 1.8t variants are different from the North American 1.8t Golf and will behave differently when tuning with the JB4. For example, many ROW 1.8t's have variable exhaust valve timing while the North American 1.8t does not.

Yup. When I went fol70 trims dropped from upper 40s to mid 30s. 3AD2 code ensued. Are you having the jb4 autoclear codes steenbeck? Id turn FOL down and dial back boost a bit. I dont think 90 is attainable by any car.

Hi
90 is just the result of always lean conditions because of this stupid trims flatline. With is12 fol50 was way too low and the 3ad2 kept coming back. So I went to 60 and that was also not working really well cause when trims was stuck I was lean. The best result was with fol 70. So trims never wanted to go higher than 35 and afr was always perfect. But now with is20 70 is of course again not enough. Otherwise there would have been no need of upgrading the turbo. Now with 90 it is acceptable lets say. I still have to taper much more as I want to. So now to lower fol again and still have enough juice I try bigger injectors.

I recognized something that is kind of weird. Is there a possibility that higher trims does not automatically mean that there is more fuel?
In the last log I posted I had fol set to 90 and the afr was close to 15 with trims of 36. Now I did a log with same conditions fol 80 and the afr was 13.3 with trims of 30. Does this make sense?

AFR Seems High?

Final got caught up on this thread. Learned a lot! Thanks to all for you sharing your info!

Well, finally did a log in Map 4.

Does my AFR seem high? MAP-4-72*C-ambient

I'm at 25k miles, with all the bolt-ons, but stock DP and IC, and was on the Neuspeed Power Module previously.

I want to get new plugs before logging Map 1 and Map 6, though...

Your Fuel/Afr bias are all set to 0. Set to 100.

Thanks Diggs!

I'm in MAP 4. How do I change that? Thought it was the factory map with logging ability only?

Map 4 will show the factory AFR target and tuning. They do run lean but what is considered normal these days.

I've run FOL as high as 95. George said above 80 won't make a difference, but I do see a little better trims with 90 vs 80. This was is20 and some ethanol though. The key is to watch you fp_h as well. That's the hpfp. Of you see it drop noticeably, your running out of fuel all together. You want it to stay pretty steady with just a few numbers variation. If it goes from like 14-17 down to below 10, it's no beuno. Best is to compare other logs of your own car to see where you are typically
