you'll find attached one stock map log, one stage 1 MHD log and two stage 1 PP-PERFORMANCE LOG

I'm thinking about the LPFP
what do you guys think about it ?

Just changed the LPFP, car runs way better with better pressure for 3 days, and now, back at shitty pressure
what can i do next ?? pressure regulator ?

Morning guys can someone have a look at my log for stage1 98 Ron map (v7. 1)please?

You need to keep the accelerator pedal all the way down, all the way to 6K rpm or higher

Also, log boost mean, absolute timing for cyl 1 and timing corrections for all 6 cylinders, short term and long term fuel trims and high pressure fuel rail.

Did you bother to read anything at all about this process?

hello all, recently flashed my car to Stage 1+ E30 and would like for someone to decipher my graphs. I suspect one of my fuel pump isnt too happy right now.
below are 2 logs:

Try again like this:

How to Datalog

1. Press the Monitor (auto log) button
2. Stabilize around 2500 rpm in 3rd gear with DTC fully off
3. Mash the pedal, shift at 6000 and hold at 2-3s after the shift into 4
4. Slow down, stop the monitor.

Relatively new to MHD, I will try your suggestion. Yes I'm aware of the need for going full throttle till 6k at least,

I'll log those entries as well, I realised I made a mistake, forgot to turn traction fully off,

Thanks

Not sure if this has been discussed before, but can someone explain to me why the wgdc doesn't go up to around 100% when boost isn't being met in the upper RPM's? It'll jump all the way up when I first step on it, but toward the end of a one gear pull it doesn't go above ~60%, even though it's missing target boost by a couple psi.

I'd be a bit more concerned with you rising IAT's, rich STFT's, LTFT's not being at 0 during WOT and Throttle closures.

Do logs in psi not bar.
FYI I have never seen a WGDC do that before....

[magsmagsmags]

advice welcomed on the below log

Some context - plugs on bank 3 were fouled / carbon deposited. coils and plugs new.
The STFT and LTFT are way out from each other, with random spikes, i think the issue is bank 2. I have new O2 sensors front and back going into bank 2 later.

Thanks for the feedback. I know my FMIC isn't the best, but it's not the worst either. And I just assumed the throttle closures were simply preventing overboosting. Do you see an issue with this? My trims are certainly out of whack and I am concerned about that, I just don't know what the next step is. I don't want to replace injectors and find out they're not the problem, especially when my AFR looks fine. Do you have any advice on where to go with that?

Fuel trims look fine. RFP just runs aggressive fuel scalars would rather it pulling fuel than adding, Can be corrected easily. Also yes slight throttle closures keeping boost down not really anything to be concerned about. Reducing abit of WG in that area will fix that. Overall looks good for OTS tune

5th gear log w torque limit 4 dropping timing to negative values.

Here are some logs =>https://datazap.me/u/ludovic-poviac/...og=0&data=2-19

i know about the WG issue but let's focus on the low pressure fuel
it's reading too low

just changed fuel pump and pressure regulator/ filter

really don't know what to look for

[Saif2018]

Hi all,

Could you guys have a look at my log and let me know if everything looks ok?

https://datazap.me/u/shelim2020/stag...=0&data=3-5-20

Many thanks in advance.

[Chris1337]

https://datazap.me/u/chris1337/shit-start been getting long cranks and rough starts. fbo stock turbo with PI and full e85. never did this before

Doesn't appear to be any issue based on the description you presented. Would need to see a log to be of more help.

FWIW, my WGDC hit 100% at low RPMs on stage 2 aggressive at WOT onset.

Thanks for the link, but unfortunately it doesn't really get at my question. I understand why the wgdc ramps up to around 100% when you first step on it in order to quickly build boost. I'm just confused that it doesn't raise the wgdc more up top when it fails to meet the target. It's almost as if some other parameter kicks in, telling it to be a little more lazy up top. I obviously have no idea, but do you understand what I'm getting at?

Yeah, I thought it wasn't meant to ramp up, when it fails to meet boost later on the rev range.

Perhaps you can ask someone more knowledgeable on the thread.
