First set of logs.

///Macht · 05-24-2013, 11:39 PM

Logged my first WOT pulls tonight in preparation for a PTF e-Tune, and I'd like to know what I'm looking at. I'm running stage 1 aggressive with a BMS dual cone intake and a 25% E85/93 blend (4.000 gallons exactly). The logs themselves are hieroglyphics to me, so how do they look?

What gear where you in? Looks like you where in second gear or 1st because the logs are so short. You need to do some 4th gear wot pulls to actually see numbers.

Everything looks good to me

Give this thread a read in order to get a better understanding of the major channels and what to look for in a log http://www.e90post.com/forums/showthread.php?t=696472

Was in 3rd gear. Pulled from 2000 RPM until around 6000 and let off.

So, from what I've read in the past about stock to stage 1 gains, I should expect a 70whp bump over stock (running stage 1 aggressive, 25% E85/93 blend). Using the logs I attached in the original post, I'm seeing 319whp for datalogs three and four, and 298whp for datalog five on Virtual Dyno. Is this normal? I've just stumbled upon Virtual Dyno, so I'm not sure whether it's accurate or not, so I'm just curious.

70whp gain from just a stage 1 tune isn't really likely... more like ~50whp.

As far as how accurate is VD? Well, that depends on you. Weight, tire size, road conditions, traction and a number of other things all play a part... but if it's all on the up and up then it can be fairly accurate.

Keep in mind the point isn't just to get a set of numbers, it's a tool to track progress. If you're consistantly seeing 300whp then make a change and start seeing 330whp(all things equal) then you're going the right way.

Took a longer look at my first log, and noticed at lower RPM, requested boost and actual boost aren't very near to each other, but at higher RPM they even out with each other. Is this normal?

Ænema · 05-25-2013, 01:04 AM

Yep, it takes time/RPMs for the turbos to spool enough air for actual boost to hit requested.

^ agree took a sec to decipher log but all looks great at least in first log didn't look at the others .

///Macht · 05-25-2013, 11:39 PM

I did a few more pulls tonight. Feel free to take a look! Datalog 6 was a 4th gear pull for shits and giggles. Datalog 7 was a 3rd gear pull, but auto-shifted around 6600 RPM. 8 and 9 were both 3rd gear pulls.

Using Virtual Dyno, datalog 6 showed 340whp (4th gear), datalog 7 showed 407whp, datalog 8 showed 338whp, and datalog 9 showed 346whp. A considerable increase over last night.

All the logs looked really good.

Logged the first iteration of my custom tune for stage 1 aggressive and an E85/93 blend. Clocked in at around 384whp running only the AccessPORT and a DCI. Will include incremental updates as we go.
