How does my log look?
FBO, STG 2 FMIC ST (v4.02)? running 91+e85
Fairly new turbos about 2.5-3k on them.
3rd gear pull

That is a VERY good looking log
You should add STFTs and LTFTs to be sure your trims are in good shape. However, your AFRs are good so your trims aren't maxxed.

The only thing i see that isn't perfect is that you are having a slight overboost condition between 3600rpms and 4100rpms, however it wasn't enough to cause a dip in TPS so i wouldn't worry about but I would keep an eye on that in future logs just to be sure.

Thanks! What should I remove from the log to make room for LTFT and STFT?

I may switch back to the e30 map and get a few logs in a few days, now that the v4.03 map is available.

OH! and I forgot to say I'm in Denver so I'm at about 5400 elevation?

You should have room for 2 more channels so just add STFT bank 1 and LTFT bank 1. If you don't have room then you could switch out timing corrections on cyl 2 and 4.

At that elevation your log looked good, no problem hitting req boost with plenty of WGDC to spare.

Well thanks, thats good to hear. Especially considering my new-ish turbo's are already starting to slightly rattle, mainly on cold startup. Is that normal? Once the engine runs for a minute it goes away. I would have figured they would have gotten a lot more miles before I heard any kind of rattling.

I'll get a few more logs over the next few days.

Thanks

Unfortunately, the WG rattle is normalish with catless DPs. Mine have rattled during startup but stopped immediately after for +20K miles(that's when i installed catless DPs, they probably were doing that before then.)

1. AFRs look good
2. ZERO Timing Corrections
3. Next time you take a log, try to stretch it from 2.5k-6.25k if you can

I'd also recommend you switch which cylinder you're logging the timing off of from Cylinder 1 to Cylinder 3-5. Cylinder 1 is on the end of the block & tends to be a less accurate representation then cylinders closer to the TB.

Just installed VRSF Down Pipe and put Stage 2 Tune Aggressive.

It feels slower for some reasons.

Attached Datalog Stage 1 and Stage 2.

Just confused :S

I used Virtual Dyno to measure HP and it is less than before (I know this is not the holy grail but it is a good tool for comparison)

Well, both sets of datalogs(stage 1 and 2) looked really good. I recommend resetting to the default logging channels, the way you have it shows only cyl timing on on the stage 2 logs(it's easy enough to tell if your having corrections but not as easy as with the timing correction channels.)

As far as comparing the two: Stage 2 runs more boost in the mids than stage 1. The stage 2 datalogs have higher CATs, high enough to trigger the CAT correction table so your timing isn't as good as it could be. That means that the timing on stage 1 and stage 2 looks really similar. On a cold night the timing on stage 2 will look better.

There's not really a BIG difference beyween stage 1 and 2 to begin with(with the exception that stage 2 should put down more torque in the low-mid range RPMS) and with those CATs on stage 2 it's even less of a difference. The car should still be a little quicker on stage 2.

Reset ECU learning. The car still has to relearn itself. Drive it around a bit, do some pulls and let it sit for a bit.

This happened to me when I first switched to the e30 tune. Felt like crap at first, then I drove it the next morning and BAM!!

I uploaded ST map as I think it's better overall, Reset ECU, drove the car and did 2nd gear run again.

First run, there is a timing pull on 1st Cylinder. Second run, timing pull on 2nd Cylinder.

Not sure :S

Overall I think you guys are correct. Top end is the same however there is more torque down low around 3000-4000ish rpm.

What fuel are you using?

[eriktufa]

I always use 98 RON (93 PON equivalent).

PS: I just put in new oil filter, engine oil (Liqui Moly 5w-30) and transmission oil

[Koreyy]

08 335i coupe, Cobb ap stage 1+ ST aggressive v401, Ets 5 fmic, Stett Cai, Bsh Occ, Helix Bov.

can anybody help me reading logs? i searched and downloaded virtual dyno program and dont know exactly what to look. can you guys check my log out if its okay or bad just for this time please?

You mean 93-94 AKI equivalent

Yes That's Correct, 93 for people who lives in US.

from what I could tell looks pretty good. to be sure do this:

try to just do a 3rd Gear Log, WOT from 2500 RPM to redline or 6500 RPM. go through 4th for a bit. read that link I posted, it will help you help us.

this will also clean up graphs and charts when using VD or Excel Grapher.

but somehow i feel your 98 Ron is still better than 93 AKI.

+1,

gotta have a few WOT pulls before the car is fully adapted to the new tune.
