Log looks pretty good. A few timing corrections - maybe just weak gas. Got E85 available? Might add a gallon to a tank to up the octane.

Question - why is my throttle not at 81% ?
Boost solenoids ?

Thank you in advance

The log looks ok, except for like you said - throttle closures. I've never seen a log where it closed the throttle the entire pull to maintain boost target. Are you on stock turbos? Maybe the wastegates are too loose? Hopefully one of the pros can give their insights.

OK guys, here's a unique one. What tables in the tune can cause WGDC after PID to be limited to 40.2? I have confirmed that this is tune related because it's not an issue on the stock tune or OTS tunes. However, the WGDC and boost control tables in this tune works fine on other cars. So there's something about this tune that this particular car does not like, what could it be?

WGDC base is aggressive for 2 reasons; 1. high altitude tuning on stock turbos and 2. in order to show you guys WGDC after PID is not following the base.

I've tried lowering load so boost is on target (among other things) but WGDC after PID is still stuck at 40.2. Any ideas?

Wgdc limit seems set to 40.2.

Yes it does seem that way but it’s not. It’s been set anywhere from 70-85 with no change.

When was the last time your plugs were changed?

Did the plugs and coils less than a month ago.

UPDATE: Started running Stage 1, and holy crap it's like a new car! I'll have to do some logs this week. Is 15lbs normal for stage 1? I thought it brought it up to 12 max... I don't want to break something lol.

I keep overshooting on the V.8 maps v.7 is alot better. I cant find a boost leak (smoke tested), new plugs and coils, never walnut blasted.

any advice on where to look?

Kens making me a map RN but in the down time im just curious if anyone sees any other Blaring issues. The car currently oscillates a bit in gears 4-6 especially, from 2400-3000rpm (feels like bad plugs/coils, they are brand new). issue is most apparent went going from say cruising in 6th, downshifting to 5th and right as you tip in it oscillates a bit then pulls smooth?

Ngk 5992's @ .020, Running 92(e10).
FBO, no inlets/outles.

TIA!

Its not really an overshoot as such. Since this is a manual trans you will just go way over boost target when you lift to shift and the DME is closing the throttle for that reason. Mid range in 3rd and 4th is where you really need to look at close for Boost target vs mean deltas. The boost is over target at about 5500 in 3rd and thats where you get most your closures - not really a bad thing. Just a side effect of the limits of the OTS map.

The custom map should help. It will move the load targets up a bit and give you a little more headroom, but Im not sure how much it will help with 91octane.


Reset vanos adapts and maybe LAMBDA controls for the surge condition.

335e92tx thanks for the input!

Yeah im not looking for more power, i contacted ken for a custom map, just looking for something more tailored to me.

On a side note, when i shift fast, even with a double clutch or a slight slip on tip in, the BOV doesn't vent, and it feels like a slight surge? could that be part of this? its a tial 50mm with the whole tapped manifold etc..

it only happens when your doing say a log, or a glory run. no pssttt, just shifting right into more boost?

Fixed. Turned out to be the boost solenoids. Replaced and all good now.

Could someone take a look at my logs below? I'm currently running V7 Stage 2+ 91oct map. Want to make sure things are looking good before switching over to an E30 map.

Eh, I imagine there is still some predictive stuff going on in the DME and it will start to close throttle butterfly before you hit the BOV spring load.

For one, Im seeing ambient air at 14.1psi. Thats like at least 1100 feet right? That will affect how both spool works and also fuel trims in the 4500+ range.. (trims to a lessor degree than spool). That is at least one thing a custom tune will offer over the ots MHD maps (which are really optimized for ~14.6).

Ok, next
- I dont see boost mean. Make sure that variable is turned on

- Little retard on 4 and 6 mid pull. Not bad. Id watch for that in a future log. Not bad otherwise. See if you can get a little of 4th gear in a future log. Something more than the 91map is where you could get more power if you had access to some more octane.

Could someone help me with the following problem:

- WOT throws the 30FF code every time on 3rd gear (no other fault codes triggered)
- It happens on both MHD stage 1 and 2 maps (7 & 8 beta), the stock map works fine
- It can be seen from the logs that the wgdc bank value suddenly drops during the acceleration and most probably that's why the boost drops which causes the fault code: https://datazap.me/u/palze/mhd-stage...ta=3-4-5-20-28
- The car is E92 335i 2006/11, 100k mileage, stock turbos, catless downpipes

Does anybody have any suggestions where to look for to fix this issue? Thanks in advance!

[Diabetes2011]

Could someone look at my log and help me address a couple issues and maybe some other red flags I'm not aware of? I'm sorry, I'm new to logging and trying to learn as fast as i can.

1. I'm concerned about my timing corrections, am i going to hurt something? and how terrible are these corrections? I just preformed a walnut blast, changed the spark plugs and coil packs. As for fuel I was using some lower quality 91oct with both Lucas octane boost and royal purple injector cleaner.

2. I am far from my target boost in higher rpm. I just ordered the GFB DV+ Performance Diverter Valve to help, could it be anything else?

I'm sorry if any of this is obvious I just don't understand the reasoning behind my correction and not hitting target boost. I'm eager to learn and thankful for anyone's help!

Your graph log seems to have recorded timing and not corrections unless I’m seeing something incorrectly?

The corrections are labled as "cyl1 timing cor*". My log has both timing by cylinder and timing correction by cylinder. Here's a screenshot of my most recent logs. Two seperate pulls two seperate days, all 3rd gear WOT.
1.Day 1 Correction
2.Day 2 Correction
3.Day 2 Actual Boost vs Target Boost
Thanks for looking!!!!

Ah apologies that didn’t show on mine for some reason when scrolling up and down through the parameters. Perhaps I had the wrong log.
