2007 335i (AT) Cobb Datalog Stage 1 93 octane

TiAg335i · 04-09-2011, 03:48 PM

Here are the results from a 60mph pull to about 100mph...to be honest I wasn't quite sure how to drive the car to get the best results but feel free to give me advice. I did another pull (3 pulls total) but it didn't seem to record it? I thought the Cobb was able to store 10 logs...

Edit: having trouble making the graph...there are really no distinguishable lines even though I try and make a line graph...any excel gurus here?

I attached the files below...not sure why the Datalog1 file has such little data...maybe because I ended the logging too soon.

The 1st datalog looks like a dud but the 2nd one shows that AFR and boost are both hovering around 15 with no apparent spikes

Go to the the Cobb forums. There is a "how to" there for making nice graphs.

Hey man,
the logs you have there are not enough to show anything. you want to do a 3rd gear run covering all he rpm band (~2500 -> 6500). Record the whole run then post the data in csv not txt. Makes it easier to graph or at least read

Thanks...like I said I didn't really know what i was doing. I'll try this next time. E90post wasn't accepting csv format that's why I did txt

You're right it doesn't accept csv, so save it as csv, change its extension to txt. then when we look at it, we'll just change the extension
