Here's the link for the new log. Had to roll on to WOT in 3rd to keep it from downshifting. Looking forward to the option of turning that off once I do a tune.

Go back and pick more pertinent parameters. Have a look at the logs posted over the last few pages.

Hello,

I'm trying to build myself a 91oct map, if anyone is inclined - please take a look at my log? I'm feeling like boost isn't building as fast as it should? On the top end it's holding pretty good but it's wonky to me. Meaning low side the wastegate settings are really low and then to hold top end it's set pretty high (referring to my wastegate table). If I don't have the low end pretty much zero'd out it will overboost.

I'm running dp's, dci's, stage I LPFP (yes I do run e85), new plugs,coils.

You can zero in the low rpm and high, because the tables have maf req wgdc as the x axis in the base table. Your are obviously quite off in boost at high rpm. Wgdc adder can also help, when scaled to higher maf req.
Also, wgdc pid, in addition to base needs to be logged to zero in.
Your base is very low at low rpm, probably has lot of pid activity or adder

Thanks! I will make some changes and post back. Part of what I was running into though was when I give it extra WGDC down low the car will over boost. It seems to want to overboost low when it has ANY extra WGDC.

Also, I was under the impression that if you are using WGDC (RPM x Boost Setpoint) that your "Adder" and "Airflow" tables weren't used?

I Dont use rpmXboost setpoint and im not used to it, so i see your dilemma. I think you can dial in well w the wgdc method.
My guess is adder still applicable, even w your method? That would help
Feel free to post the rpmxsetpoint table...

Can someone take a look at my logs? Have been on Stage1 since the Beta days. This weekend I installed VRSF DPs and flashed stage 2.

RPM x Setpoint FYI...

What he said - do set to default.

[Anend_E90]

Here is a fresh log - 2008 335xi, 5in FMIC, DCI, CP + Tial BOV - MHD Stage 1 FMIC 93 Octane.

I see boost over target now, I was building slowly before and swapped out vacuum lines and now things feel much snappier but the 1-2psi over boost seems strange to me. Solenoids maybe?

Since you went from vacuum issues to no vacuum issues, reset adaptations and see if the DME adjusts it's request for more boost.

That's where I'd start until the experts respond, at least...

okay Sgop335 - I upped the wgdc just a tad and logged the boost error p and d-facts.

New logs - noticing that (spool) below 3200 rpm I seem to have a problem - and above it seems better?

Notice Base is very high at 2500 rpm and less, pid should be high there during spool not base. Must be those high 75s. Wgdc pid preferably should be logged.
Have you messed w the pid table at all?

I have not really messed with the PID much. I've got a couple different 'base' maps that I tend to alter by little bits.

I will get that parm logged and post up again. Yes, I placed those 75s in there trying to get it to spool up.

Pid tables, pfactor, i and d factor can handle spool very well. I and d tables can be stock but p factor is varied to give better response and control overboost. There is also a dfactor multiplier table which is reduced to prevent over and undershoots. .you can see my log below to see how wgdc pid and base vary

[Ballistic]

Hi all!

Got a log right here.

http://www.datazap.me/u/ballistic/mh...=0&data=3-5-22

Don't look at the iat's and timing corrections. I need a better intercooler

What i am wondering is why i don't reach boost target in 3rd and 4th gear. At the worst point i'm 1.4psi under target. There are a lot of explanations for under-boosting.
What i don't get is why the boost is spot on 18PSI in 5th gear.

If there was a boost leak it wouldn't reach targets in any gear right?

In every log I notice an closing throttle while my pedal is completely floored. Tracion control is off. I've read in your write up this should be minimized in V7. Is this normal behavior?

datazap.me

Yep, throttle closure is normal on stage0 (OEM map). Some timing pulls on cyl2. I would watch for that and just go to stage 1 with the best gas you can get.

Well, I think dimitri will be better able to speak first hand but hopefully I might have learned something. I guess this is EU fuel? And a 95octane map? Everything I see looks pretty good. Lot of boost there.. I would think it would be a little closer to load targets. But I dont see anything real obvious as to why. Maybe a little richer than I would have expected.

Id also see if it changes the boost curve. Any chance you might have some leak in the pipe?

I do suppose there could be an intake leak somewhere. Would that be the only reason for the timing adjustments? Thanks!

No, generally timing being pulled is bc not enough octane (and or possibly plugs or coils starting to give up). The boost targets not being close to actual is more likely the cause of some coupler.

All that depends on how close someone might be to the map being too aggressive or not.. but once you get a certain map and fuel blend dialed in, it should be consistent.

Update, just refilled fresh 93 from another station (Sunoco this time versus Shell before), and still plenty of corrections, including one big enough at 3k rpm to feel a definite miss.
