Try to log at least in 3rd gear or preferably higher, multiple gears if you can.

I am not so sure. Did you see the HPFP drop to 1600? That doesn't seem correct to me? Why would it do that on a 91 map?

Jnat · 01-16-2022, 09:09 AM

i'm thinking anything under 2000 psi is cause for concern so agree...

IMS-340C · 01-16-2022, 09:23 AM

Yeah noticed that but timing and timing correction are ok, the ECU will close the throttle or pull timing if something not right.

But as I said it's a 2nd gear log I would like to see a proper 4th gear log for better judgement.

Adding mine here.

Seems like last replacement of spark plugs was not going well.

IMS-340C · 01-23-2022, 05:19 AM

In terms of safety and performance logs are good, some corrections here and there but nothing dramatic.

Most probably the DTM light and missfires are a result of very low fuel rail pressure not spark plugs, could be a sign of HPFP failure.

Other than DTM light and missfires are you noticing any long cranks ?

Thanks for the review.
I have replaced spark plugs to the correct ones(NGK) and gapped them to 0.5mm.
Some time ago I have also replaced fuel injectors, though that might be a reason as well.
HPFP is TU oem, it's 1 year old.
I will try to test it again, after snow will stop here.

Is it a case that fuel pressure is low after switch of gear, because of disability of 3,4,5 cylinder?

IMS-340C · 01-23-2022, 07:28 AM

No, fuel pressure drop occurs in gear.

Check what fault code the DME registered.

Pretty easy. Recorded them.

T_H_O_M_A_S · 01-23-2022, 07:49 AM

hpfp behavior is normal , post shift your rpm drops , so output aswell , the quantity valve adjusts and comes right back up . although the resolution of your logging seems low , or is it normal in mg flasher ?

once again why gapping ?

Seems to be normal in mgf. I can increase a resolution of logs, could you please give me some hint on soft which I can use for this?

Thanks

T_H_O_M_A_S · 01-23-2022, 08:21 AM

maybe some users with xp in mg flasher can help

putting your units into psi is easier to read , because its mainly used overhere

https://datazap.me/u/thomas/stg2-hpf...ata=3-17-18-20

this is how its looks in mhd , yours is too rough

IMS-340C · 01-23-2022, 09:03 AM

It's not post shift it's in gear, hover to 5000 RPM in the log below, fuel pressure drops from 20 mpa to 11 mpa:

T_H_O_M_A_S · 01-23-2022, 09:19 AM

its paints a different picture

anyway i would start with oem plugs and gaps anyway and relog
forget the gap bs

Could it happened because of misfire?

Hi Guys, I have a Stage 2+ 340i using BM3 OTS 93 Oct tune and brand new TU pump.. Just wondering whether you can give some inputs to my data-logs as there are some "knock detected" -- during normal driving and some on WOT. Is this troublesome?

I see that Cylinder 5 continue to see the biggest timing correction mostly, is this a cause of concern? How much timing correction will start being a problem, >5 degree?

Logs on normal driving:
https://www.bootmod3.net/log?id=61e2...729b3b8e49702c
https://www.bootmod3.net/log?id=61eb...729b3e67787c7a

Logs on WOT (through several gears):
https://www.bootmod3.net/log?id=61eb...90c640becd3103
https://www.bootmod3.net/log?id=61eb...729b40366d4ec5

Just wondering whether its the bad fuel octane, bad spark plugs (it is only 10k kilometres old) or heat?

IMS-340C · 01-24-2022, 03:05 AM

If Fuel pressure target also drops I would say yes.

Try re-gapping the spark plugs to original gap, if it didn't work buy another new set from a different source.

Hello!

Could someone please explain me what is "ignition angle" (vs timing correction), and what value is considered normal?

Thank you!

b7ff · 01-26-2022, 05:32 PM

Any help or input for the below will be much appreciated guys, I am considering to bring down my tune to Stage 2 91 Oct if you guys think this is NOT safe.

Base Map E85 logs with Vargas GC ...car felt a bit faster than my 93 map but nothing crazy. A few more degrees of timing up top (2-3 degrees) but similar boost to 93 tune ... thoughts???

WrxToBeamerGuy · 01-28-2022, 07:38 PM

My timing pull is terrible
My HPFP is dropping during a pull
My boost is off target
My AFRs are fine

Is all of this because of my HPFP dropping off? I have terrible fuel here in Utah (91 Octane) but I did dyno tune this car in the summer with PJ.

This is stock turbo, stock fuel pump.
