Since you just installed you G5 ISO and loaded the 27.5 firmware (newest firmware), make sure you restore defaults, just to be on the safe side so you can enjoy the tune to the full potential also make sure you go to settings tab and make sure look at the drop down menu to make sure your running the G5 ISO. I think its usually on G5 when you first get it because thats in the interface, not the actual board.

If I was you I would personally find someone in your area that does coding/flashing or do it yourself if your a tech type of guy and run the E85 flash. Just make sure you save your original BIN file. Put in about 4 gallons of E85 when your tank is on empty for the first tank and dont dog it around, let the car understand what is going on but after about a quarter tank is gone do a 3rd gear roll from 40mph thru 4th gear if you can letting the RPM's go to 7K redline on map 5 about 4 or 5 times for it to learn since its the autotune map. After the biggest smile you cant get off your face, at about a little less than a quarter of a tank, put in 8 gallons of E85 and the rest 93, which is usually around 5 gallons or less. Let it run for a few minutes before leaving the gas station and drive it normally for about 10 minutes or so to let it fully mix. Put it on map 7 and get ready to become literally ADDICTED Make sure you take traction control all the way off (hold DTC button for about 5 seconds) because the tires are going to for sure spin, even on stock turbos continue to fill your tank up with atleast a 50% E85/93 mix.. Then your mind will be BLOWN away

and just incase your wondering about if E85 hurts your car, it DOES NOT. I personally have been using it for almost two and a half years now, maybe more and I just got my first HPFP replaced about 3 weeks ago. Of course back in the day I would only put in 2 or 3 gallons but man that 2 or 3 gallons made huge gains and I got addicted just like you will
Sometimes certain cars cant even handle 50% e85 without a lpfp upgrade. He'll have to do some logs first to see whats going on.

Terry, what are the actual usable values for dash setting 12? The Spreadsheet on first post says 25-30 but I see several posts in here where folks are running as low as 19 and as high as 35. Running 27.5 with latest flash but still trying to work out some rattle on light gas pedal. Thanks!

I think we moved the range to 20-40 in one of the 27 versions.

60% isnt an issue... above that yea. But No 60% isnt an issue at all if your lpfp is running fine. Your lpfp must be failing.

I believe 10 = 50 and 12 = 40 so you are at the max.

I live in France, so I put 30 liters of E85 and 20 litres of 93 pump gas.
My mods:
Jb4 g5 iso 27.5
BMS BB flash E85
BMS DCI
Helix FMIC
Alpina b3 flash
RB pcv valve
Midpipes uncatted

My LPFP is running above 50 psi all the time.
I have 50000 kms, so 35000 miles.

Hello all.
Can anyone explain how to best adjust the "Default Wastegate Position" and the "Base Duty Cycle".

What I'd like to know is when each of those values comes into play and how.

On idle?
On Deceleration?
On Partial acceleration?

I searched but found no conclusive explanations.

I thought that the LP should be in the upper 60-70psi range under wide open throttle?

As long as the LPFP pressure is not below 50 psi, no issue.

Well I have been having LP fuel issues for a few weeks. Logs were showing 30-40psi at WOT!

First I replaced the LPFP and relogged. Logs only showed and increase of about 5-10psi across the board.

I then replaced the fuel pressure regulator and fuel filter assembly which BMW states is a "lifetime product." Just relogged and fuel pressure is very high 60s to low 70s under WOT in 4 gear! Problem solved!

I'm headed to the track tonight to see if I can beat my previous trap of 117.64mph.

Thanks..

Part number: 16147163296

I definitely recommend doing both at the same time. I wish I would have done this! I'm just glad it's fixed now. I have 93k miles on my car, so I am sure the filter was due
for replacement. I don't understand how a filter can be a lifetime product....
