To much variables in the log, these in this log is enough https://datazap.me/u/blown95impalass...=0&data=3-5-22

Its stock, no tune yet. I just got the MHD monitor so I wanted to get some datalogs and see if anybody notices anything thats off. I had all of the variables on bc I wanted to be able to review everything. Its been running a little rough and has wastegate rattle so I wanted to see if the logs would provide some reasoning for it. Im replacing valve cover and gasket in the next few weeks bc it has some cracks and is leaking oil, and also gonna replace spark plugs while im at it.

lol you guys funny,
at least a 3rd gear log.

[335e92tx]

and a little of time after the shift into 4th. IATs will be a bigger factor then and loads will put timing closer to limits.

Quick question to learn more :

The other day, i was cruising + doing some pull and logging WGDC banks, and noticed that i soon as i touch my pedal, WGDC banks spikes down (opening) for 0.5seconds and then jump immediatly to ~90% (closing).

Is it a standard behaviour for wastegates to open (from ~50% to ~30%) before closing to ~90-100% prior WOT ? Why does it not close directly from 50% to 90%-95% ?

Mine spikes down, found a few log with the same behaviour, but it looks like it's not the case for everyone.

See two pics (same tune), one not doing the spike down, one doing it.

What does it mean? Any light appreciated

Got 2 logs after i m fbo+ relocated inlets.
Some overboost between 4-6k rpm and some throttle closure. Some timing correction, but looks acceptable to me. Fuel pressure seems ok. Anything that doesnt look right to u guys? Thx for any input

The drop is normal i have it to in my logs, my guess it is du the vacuumdrop when you open the throttle but can also be programmed in, but i do not affect spool in my case

I only see 1log

12*C
Fbo + relocated inlets
91 OCTANE

cyl5 got a big random retard at about 5100 rpm. I would look for that again or something similar. Your barometric pressure is 13.6 so you are over 2000 feet elevation I think. Your WasteGate Dcs are good. Someone that knew what they were doing could get you a custom tune that wont taper boost as much.

Yes, i spoke about 0.5sec, but it's probably really faster than that, it's like you push pedal looking at the gauge, it very quickly drop to 30% on the gauge, then immediately go to 90-100%.

WGDC bank numbers are commanded by the DME, so it's probably programmed rather than a vacuum drop ?

It's weird, cause some people are droping, and some not, with same MHD maps.

Why adding some extra travel to wastegate arms??

Maybe it has to do with the linear throttle option activated or not?

I don't use this option, and i have the drop.

This should be the other one. Good eye on the baro pressure, yes i m at 2200ft.

Is -3 timing correction too much? I thought as long as not pulling more then 3* on more than 2 cylinders at a time is ok.

No, but it should not happen just right in the middle of the pull (well, it happened on several cyls mid pull on this newer log). Its generally at peak right after a shift. Try to get a 3rd gear load and just a few secs into 4th.

It looks like your IATs are going up 20 to 25 degrees in like 7 secs.
Yall got a heatwave in .ca?

So what IC is this?

It was a cool night, but those two log were already the 5th and 6th pull that night. First 2 pulls were only in 3rd gear. Iat went up 12 and 15*f. Some of those logs werent clean and even had one in forgot to turn dsc off. Its a ams ic btw.

Ok. I think i will bump it down a map just to be safe for now. And do some log when i have time. Thx for the help!!

https://datazap.me/u/chevyb08/log-15...=0&data=3-4-15 Can some explain why my boost is not holding target and why it’s diving so low 2011 335i

Do a proper log session and we maybe can help you

I dont see boost mean logged. IT can be inferred but thats not ideal.
You can probably turn off fuel mode, oil pressure and add lambda and Long term trims for bank2. Blend factor and boost overshoot and all the other boost* ones except target and mean are not really relevant.
I dont see short term trims there. Make sure you get them for both banks. And try to get a thrd gear run with just a few seconds of 4th after the shift.

Its pulling timing pretty bad on the shift to 4th. Just about 3degree retards across the board for the first few secds. Thats keeping you from getting back to load target very fast. It only is a little better near the end of the log. It doesnt look like IATs or lean fuel is doing it. Just a little agressive on the map right after the shift. Not sure how much predictive stuff can be done with the DME for a manual trans to pull a little timing before the shift or maybe add a little fuel. Its right in the range of 4500-4800 when you need to be at max boost and timing. You got any access to methanol.?

You say today, if that is truly the case I would give a little more adapt time and then try another log.

Yesci flashed stg2+ 10km before log. I had before stage 1+ without intercooler. Best fuel i have there is 100ron. I am from Croatia-Europe. Maybe need some time for adaptation.

Ok thanks I’ll try to get another log today

Retards on Cyls 1 and 5 dont look good in higher gears. Is this thing using any oil? It might be getting some in those cyls. Id start with a compression check and expecially see if those cyls are out of range with the others.

Looks a little lean. But not bad. I would try to get load target in there along with actual.

Are these stock heatrange plugs?

Maybe try the v7 e30 map.

This log was from last year when I was custom tuned and it looked beautifully:

https://datazap.me/u/rnmevo9/bq-e50-...og=0&data=4-21

I just took some recent logs and I cannot seem to recover timing post shift on the same tune:

https://datazap.me/u/rnmevo9/summer-...og=0&data=4-21

Plugs and coils have about 5k miles. Is my hpfp dying as well? I noticed it isn't as 'strong' as it was last year. The only other difference is that the new log also has stage 3 xhp transmission flash.

Thanks.
