Try increasing rail pressure. Not sure what pressure the stock PRV on a BWA cracks open at though.

Can someone explain how hfm6 has to be scaled correctly in med9?

Try to change the map like the attached file.
bigger values, bigger maf,
small values, stock maf,
third line is difference in %

If you have 170g/sec right now, you will see 230g/sec i hope

whats your pipediameter where the maf is plugged in?

Hi! Thanks! Are you sure that this is the right procedure MAF Scaling?

At first Revo says: "MAF housing scaled to correct factory specification." But it is not true, browsing forums there are lot of people with revo/apr intakes without scaling and with Timming pulls problems.
I this that oem pipediameter is aprox 2,55, and Revo intake is near 2,75

Also Revo says: "Intake compatible with K03 & k04"
Oem k03/04 intakes are the same?? Huh

Thanks! Regards!

i know its off topic.

but what is up with your STFT between 5k-6k RPM?

I think it's intake fault. Low maf reading, low fuel inyection...

Regards!

No im not sure because i have no knowledge. This is copy past from a file with bigger maf.

Regarding fuel, you should log 1,103 and 106 in one csv.
Maybe low pressure side is bad, maybe high pressure is.

Which hpfp does the car have? hitachi 9.x?

Would recommend to mount old intake and fix fueling first.

Hi! I do you think there isn't enough fuel?
Hi log Low pressure pump & High pressure pump and pressure was constant.

032 lambda partial adaptation was 1% before install intake. Huh

Thaks! Regards!

Lambda Regulator in measurement block 1 is at 25% and that is all it can do.
Also injection time is up to 8.xx ms which is the limit!

Ummm.... I thought 8ms was "usual" on tfsi remaps.
8ms, is the limit?

I also think it may be due to very rich target-lambda, I will go up to: 0,78 lambda high revs.

You don't want your injector duration to be that high when you're at higher RPM. If you don't want to raise rail pressure, reduce your requested load.

Is this a standard calibration? If not, up rail pressure.

FPRV will crack at 129bar, pump will struggle to do that in the mid range depending on boost, but will cope top end. Ask for 120bar and log again.

Also, have a look in the AWEA module. You can up the injection advance which should give you a bit more spray window.

Hi for helping me!
I log lpfp, hpfp, load y boost.
Betwen 5500rpm-6000rpm maximum performance on fuel pumps can be appreciated.

Could be failing any fuel pump?

Thanks! Regards

Depending on injection angle and ECU settings 8ms is pretty maxed out.
Start from stock tune and make it from scratch, this is a waste of time.

Have you logged this with stock intake and stock maf maps?

2nd picture shows 103 with current low pressure and there are numbers from 3,5 to 4.5 bar
To be honest I have not that much knowledge about tfsi and low pressure and the controller of the low pressure pump.
But i have logged different tfsi and they are showing higher numbers for this. ~6bar

It could be rescued. 110bar is stock. Those trims will come down with 120bar.
