Your engine will not go BOOM if you try map7 on 98 RON; but it is only recommended for +100octane... Check the log - if your timing is in the basement then its a no-go long term
You can shave off a bit of that over boost with duty bias tuning. This should also give a more linear power delivery.

Here`s another log of my car.

Can someone please have a look at it and give me a feedback?

Thanks.

Looks fairly normal but you could probably use some more octane as you start pulling timing in 5th.

Thanks Steve.

Can you tell me why I have so much throttle closures? Is that normal?

Your throttle closures are actually pretty minimal for an N55 without a flash.

Do you think I should raise FOL from 60 to 65 or 70? Because Trims and AFR are a little bit high in my opinion.

You can raise FOL, but it's fine and it won't have any affect on your AFR's.

You can't unless you find a shop that can do a bench flash for you.

Your AFR's look normal for an N55 with a stock flash.

Hey Guys,

could you please have a look at my log.

I am very afraid having a boost leak. Last week I have installed a chargepipe, but it didn`t fit exactly to the connector of my wagner fmic. So I had to rasp the chargepipe and the fmic a little bit.

Thanks a lot.

Regards
Stefan

I have just did some new log, but anything went wrong.

At that Log (Log1) I have a lot of overboosting.

After that I did another log (Log2) and while staying at 100% pedal the boost was fallen to 0.0 psi? Can you tell me what happened there?

Log 3 looks okay so far...

Can you tell me what happened?

Thanks a lot.

In the first log you overboosted because your FF was too high. It's slowly working it's way down. I'd set it to 80 and see how that does.

Logs need to be done in 3rd or 4th gear from 2.5K to redline....the JB4 doesn't learn in 6th gear.

Thanks Steve. So the high FF is the reason for my problem?

Nice to know, so JB4 only learns in 3rd and 4th gear?

Yes, when the FF curve exceeds the PWM curve you will get overboost.

That is correct, above 4K in 3rd and 4th.

Yesterday I did another log and I saw that fp_l and fp_h values dropped.

Is that worrying or quite normal?

Could there be some connection that I have fueled 20% Ethanol E100 yesterday?

Yes there would be a correlation that you filled with 20% E100. Your HPFP is pretty well maxed out. Your LPFP isn't logged (there is no LPFP sensor), so it could be that the LPFP isn't keeping up and causing the HPFP pressures to drop or that you have maxed out the HPFP.

On a positive note, timing looks great. Raise your FOL to 80.

I have recently updated to N55_FSERIES_OBDII_EWG_6 Firmware.

After that my car felt very very slow and weak.

Please see attached log.

Can someone tell me what happened there.

Any problems with the new Firmware?

You're not running as much boost.

May need a little more adaption. Are you still running as much ethanol?

Yes I still running 20% E100.

Today I have installed the old firmware and everything is fine again.

I really don`t know what went wrong with the new firmware. I have already did some adaption runs.

Here`s my log from now with the old firmware.

Could you please have a look at it? Is that normal that my car only has 12.2 psi on redline with Map5? Is there any posibility to gain more power out of my car? EWG-Wires are also installed.

I am looking forward to get answers for my questions.

Thanks a lot

Regards
Stefan

Might be worth checking with Terry if changes were made to the avg_ign calculation now that 6cyl logging is enabled.

I hope Terry is going to read this threat and can say something about that case.

The boost levels between the old firmware and new firmware were pretty similar except the one that FF needed to learn up a bit.

Your I avg. does learn up a bit on the new firmware, but that may be because it's looking at more cylinders and you have some timing corrections.

If he doesn't simply send him a PM or email and ask him to chime in here.
