Need Help Analyzing Cobb logs please

azeemtn · 10-26-2011, 09:08 PM

Hi All,
Thanks to everyone on this board, I've learned a ton in a few short weeks.
Per the DIY's, I believe I have successfully created some Logs on Cobb Stage1 Sport with 92.5 Octane fuel in CA.
I'd like to know if I can run Sport mode in California with 91, but I first wanted to do a run with some better gas.

Attached are 2 pics I have from the DIY where I copied and pasted my results, along with 2 files attached.

The first one, with the word Advanced in it, is my data pasted into the DIY spreadhseet.
The 2nd one, with the word - "All" at the end, is all of the paramaters I pulled in case there is something that is needed in there I didn't put in the other one.

( I had to rename the 2 CSV files into .txt).

I did try to clean it up somewhat and take out the idle time, etc.

Any help in deciphering would be awesome!

Thanks

too much going on in the first graph.

Keep it simple:

RPM
Boost
Throttle
Ignition (Pick 1 bank that may have timing drop outs)
AFR (Pick 1 bank that is leaner)
IAT

Or

Graph:1 RPM and Boost and Throttle
Graph:2 RPM and Ignition
Graph 3 RPM and IAT
Graph4 RPM and AFR

You really only want 3-4 sensors per graph. Otherwise it gets too busy.

92.5 octane fuel?

azeemtn · 10-26-2011, 10:11 PM

Mix of 100 and 91! I'll put up some Nte graphs tonight.

Also helps to log just one long gear pull and one with a shift such as 3rd up to 7000 then shift to 4th. But definitely clean them up by reducing the number of channels logged in the same chart.

azeemtn · 10-27-2011, 12:48 AM

I took one gear shift out of here, and took out a bunch of the other data.
Does this help any?

I wish there was a DIY on how to make these charts..I'm doing the best I can.

thanks

are having traction issues? DCT is completely off?

azeemtn · 10-27-2011, 12:03 PM

Enrita,

DTC was not off.

I see I have a lot to learn.

Took me all night, but I've learned how to graph properly.

I'll turn off all traction control, run a pull with 2nd and 3rd gear, and report back.

Does that sound like the correct action? I am surmising the gear is not as important as the pull through the entire gear - is that correct ?

rader1 · 10-27-2011, 12:22 PM

Which DIY did you use?

oh wow....never knew there was a DIY with templates on here...cool!

Jeff@TopGearSolutions · 10-27-2011, 01:18 PM

DCT off all the way. 3rd gear to 4th gear is all thats needed.

2nd gear usually has traction loss and too quick of a gear. Not enough load and heat build up.

The logs look ok so far so there really isnt any reason to pursue more logs unless you want to.

azeemtn · 10-27-2011, 02:13 PM

Thanks Jeff.
I'll finish off this tank, use CA 91, and then try a 3rd pull per your directions.

I'll put up cleaner graphs too since I think I've got the hang of dual y axis graphing now.

enrita · 10-27-2011, 02:38 PM

just run 3rd gear and 4th. 2nd gear is useless...

Can I ask where you guys are doing 3rd and 4th gear runs?
