Cobb Data Log

[gomtingsuk]

Hi,

Cobb Noob here - just went out for a run to get some data log done (N54 09 135i / Stage 1 Drive ST).

Only creating new thread because I couldn't get to the last page of the Official Cobb Tuning Thread

Can someone look at log attached and tell me if anything is unusual / off that I need to worry about?

I looked at PSI, looks all right (topping out at 13.17) and the cylinder timing correction seem to be very good after 3500 (staying at perfect 0 all the way to redline)

I looked at TPS % - staying around 80%...thought I floored it..maybe not.

What else do I need to look for that may be of concern? Can someone more knowledgeable tell me if there is anything wrong?

Appreciate the help!

Here's the file..

Forgot to add - 3rd gear run

I all cylinders are at 0% corrections under WOT, and your LTFT's in both banks are within a few numbers of each other, you are good. Try and get a 4th gear pull instead of third so it has more load on it.

fyi, the page numbering on threads gets fooked up from time to time. Especially on larger threads. If you go to 'last page' you are on the last page even if it says page 42 of 45 (or whatever). You can also get a sense by the time of the last post.

Looks decent to me. You're having a little bit of timing pull from about 3k RPM to 5400 RPM. You basically want timing in Cyl 1 to keep climbing and not dropping, but it's not dropping much and stables out in the higher RPM. Could be anything from bad gas to old plugs but all in all the engine looks happy. I prefer no timing corrections at all in all cylinders but yours are small corrections.

Thanks all for your input - I'll do some more logs in near future and post.

I'll look into timing in Cyl1 and see if I can fix it with better gas / new spark plugs...easy fix

Can someopne look in to this log I dont know even how to read it.

BTW I did 3rd and 4th gear pull and I think everything is in one log so how can I separate them?

Thanks guys
