Would also be nice if you could get AFR's into the mid-low 13's.
Iím in Northern VA. 93 octane is available here, and I also found a station with E85 two weeks ago but I didnít mix it in till the FF wires were in. So Iím probably right around E15-ish on top of 93. But that ethanol might be less than 85%. my trims are high at first and then they level off. No idea why ... and youíre right about the timing too. I will try your suggestion.

How can you tell from logs how the octane looks?

I have not a clue how to get the AFR richer. How did you get yours into the 13s range?

Sorry, lots of questions

Tried map 6 on 17 psi with 98 octane (93 US) but did not feel right. Found EU 102 octane fuel and filled the car up, probably around 100 - 101 EU right now after mixing with the 98 octane.

Car feels better but i have problems getting boost on target, it always seems to hover just below 17 psi.

what you guys think?

340i MPPSK, BMS intake.

Try raising FF from 92 to about 110. Sometimes FF learns down too much and does not hit boost target.

You can lock it and disable the auto learning. But you have to keep an eye on the logs and adjust manually, as necessary.

Trims starting off high, then tapering down is normal.

When timing does not keep gradually increasing, you typically have an octane issue.

The way I got my AFR lower was by adding the MPPSK

Post logs and we can help you out.
What logs do you require the graph or the actual values in excel doc

The raw CSV files. Do not convert to Excel.

Tried with the higher ff settings but still boost will not hit target. I am not too familair with logging but I think trims and timing looks Okay, right? Is there another reason why the ecu/jb4 is holding back?

Bump it up in increments of 20. It's hard to go too high with FF on the B58, so you will be safe.

It's not the most intuitive process on this forum, but you need to find the raw CSV file on your device and upload via the paperclip icon in the post tools. Make sure you are NOT doing a "Quick Reply."

Maybe the MPPSK is in fact a different tune than the M Performance tunes. I think whp for MPPSK is listed higher than my 335 whp so that makes sense I suppose.

Haven't had a chance to try manually raising FF but will do it soon. Maybe my E85 sucks. Northern Virginia isn't known for growing corn, so who knows how high the E85 formulation is. There may be still too much gas in the mix, so I will experiment carefully.

I put the car in 8th gear and made a pull from 120-200 km/ph, around 200 the car went in limp mode. Checked the code “Fuel pressure below targe”, Does anyone experienced this before?

Yeah, don't do that, with any vehicle. You are putting major stress on the engine at lower RPM's for too long a period.

Hard to know exactly why, but I bet your high pressure fuel pressure was low most of the pull and then tanked at the end. Would need a JB4 log to confirm.
