This data log is taken from a 2008 335xi with Cobb AP V3, Stage 1+ Sport. ETS FMIC, ER Charge Pipe, Forge Diverters, recent stock turbos, recent plugs, coils and vacuum lines.

Is the car happy???

Hey Jeff,

Do us a favor and create a datazap.me account.

Transfer the datalog to your desktop and then upload it to datazap (it's free).

Makes reading logs a lot easier

Thanks DD. I opened an account and put the data there. Here's the link: http://www.datazap.me/u/jwebb335xi/m...sf?log=0&data=

I don't know whatelese to do with it there...

I don't think you uploaded it correctly try again

I tried again. When i click on the link, it sends me to a table with the data I uploaded in CSV format. No graphs or anything like that.

I think I've figured this out. Finally had time to spend a few minutes on it... Thanks for the comments guys.

You did not do a proper log.
To do a log you should have your car at 2500 rpm (3rd gear) and go WOT until it shifts by itself to 4th gear.
WOT = 100% press on the gas pedal

Thanks Mike, I took a couple more logs today. While the car feels pretty good, I'm still seeing over-boost. I was WOT from 11.19 seconds to 15.17 seconds. RPMS ran from 2,027 to 6,897 before the shift to 4th. I'm seeing over-over boost as load crosses over 180 at about 4,000 RPMs. I also noticed that actual load takes nearly a second at WOT to catch requested load. I"m wondering if replacing the other boost solenoid may help boost and, therefore load, build faster.

The guys at Cobb suggested I go into the WGDC base table and lower the values in the cells where MAF Req. and Set Point factor intersect. So, my over boost is at roughly MAF Req (246-256) and set point factors (2.086-2.153). So, I’d look to lower the cell values at those intersection points…
Does that make sense guys?


I'll show a picture below and also provide the link to datazap.

I recommend that you do another log .
turbos are overboosting but without throttle closure which is good
few cylinder timing drops , need another log to see if it is persistent
Trasmission is slipping, might just be traction issue but need another log to double check

One more log. This is from the same day, difference section of closed road, professional driver, etc.. That said, it's second gear WOT into 3rd.

You need to do your logs in third gear not second
