Not saying it isnt a good idea- just stating that you can plug in whtaever boost you like up top, what the stock turbos can & wont do is a function of the physical hardware / how small and inefficient they are up top- hence why you feel that drop off in the upper RPM range.

Feel free to dial up the boost as you see fit & we can review

I flashed the e85 backend and iím runnIng e40 again. The car has great power again and runs around 18LBs of boost with more aggressive timing on map 5. Iím getting no timing drops even on hot days. However, now my lpfp dips below 50 psi at around 5000 rpm. I havenít run it past 5k bc i noticed the low pressure on my first run after the E85 flash. I ordered a fuel it stage 1 inline pump. But now im wondering if i should have ordered stage 2. Will I be able to run e50 or e60 with the stage 1? I think the HP ratings on it were beyond what I expect.

If you plan on sticking with e40 the stage 1 should be ok.

My tune is targeting around 19LBs with decent timing now after it had a few runs in map 5 for learning. The logs running 19’LBs look fine for fuel up to 5k rpm. However, attached Is an earlier run tonight while map 5 was learning with only 17 pounds that doesn’t look too good for fuel pressures. Ill take it easy Until the stage one pump is installed. Maybe I will try map 7 with e50 after it’s installed.

Can you post the one that is targeting 19 pounds? I can only get mine to target 18.

The logs are short as Iím taking it easy until I get the stage 1 pump. Here is one of them. Some logs seem ok and some show the fuel pressure struggling. All of my last 4 logs have targeted 19.

That is pretty cool that you got 19 pounds targeted.

edit: Maybe you could look closely at the boost when your fuel pump struggles. Mine struggles on the high end, and I noticed that it struggled more when I had more boost on the high end. Makes sense.

You should be golden with the pump upgrade tho. Your stock LPFP just might be a little tired.

On another note, my car is loving the E85 BEF. I think it is making more power with slightly less boost than when I had the stock flash. Of course I want to see what it feels like with the same boost as before.

BTW, when we were talking about peeling out in 2nd gear, are you doing that with an awd 335xi?

Hopefully the stage 1 pump has me covered. I have xdelete which lets me switch from awd to rwd.

I wonder if map 7 would give me more power than map 5?

Among the gasoline maps, Map 7 has the most requirements. From what I have read, it is the most powerful until you go to a custom map 6.

Once you get the LPFP installed- throw up a log of map 7

Just finished the pump install and did a few runs (it’s 90 degrees and humid today). Attached is a 3rd gear pull with the e40 I already had in the tank. The car feels strong even for a hot humid day and it looks pretty healthy in the logs. I will fill up with e50 and try map 7 as soon as I can. The LPFP is definitely keeping up now. I’m happy with the results.

I also have a vrsf FMIC on the way. I plan to do some dyno runs in RWD mode in map 5 and map 7 once I have that installed.

Looks much better.

Some cyl noise on 5, but that’s the nosiest cyl usually.

LPFP looks solid, def a little more room to add some more e

In general this looks okay too.

Boost on target for most part, trims, fuel pressure solid too.

Some corrections, but could just be adapting still.

Any more ethanol- you may wanna switch from the pump flash

Hey Dave. The car is making great power. I have it scheduled for a dyno session on the 9th. However, I am having a slightly new issue. It seems like the hpfp is having issues sometimes with recovery after a hard shift. In the 21_26_12 log you can see the heavy dip in pressure after shifting and going full throttle again. The rpm drops a little and I can feel the car lag heavily right when this happens even though all the other numbers in the log look ok. At first I thought it was my clutch slipping (550i clutch) , but i think itís due to lack of fuel. Is there a way to log the duty cycle of the hpfp? I also included a 2nd gear log.

This feels very similar to an issue I had with my mustang. The car would increase voltage to the fuel pumps increasing pressure during hard acceleration, then i would lift the throttle to shift and the car would turn the voltage way down because the fuel pressure would exceed the desired levels. Then I would grab the next gear and floor it causing a heavy fuel demand again. However, the pumps couldnít react fast enough as they were pretty much off due to lifting to shift a second before. This caused the pressure to drop too low before the pumps were able to kick in again with the high voltage. The engine literally felt like it turned off for a second.

Do you have NLS?

If you are lifting the gas pedal to shift, the drop in fuel pressure on the hpfp end doesn’t shock me.

Monitoring the duty cycle of the hpfp- that’s not something I believe we can monitor

Forgive my ignorance. I had to google NLS. I see what it is now. Maybe that will help me?

Attached is a log this morning. Right after my shift to 3rd the car went very lean until the hpfp woke up again. I think this is more an issue with the amount of time it takes for the hpfp to respond to the change in fuel demand. I donít think itís a case where I have exceeded the fueling capacity with the stage 1 pump added. My lpfp pressure seems fine.

Given your mods- Personally I don't even think you are making enough power to really max out the HPFP to be honest.

How old is the pump?

One more thing- i see you have values plugged in for your fuel bias settings- any reason?

Zero those out, and relog for me,

I believe the pump is original. I have owned the car since 2011 and I never replaced it.

I have no idea where the fuel bias values came from. I just checked my old logs and it looks like they have been there for many years. I will zero them out and get a new log in the next couple hours. Thanks again.
