Here are 2 logs, the first was the regular Stg 1 + Sport map with E25 fuel, the bottom log, run 6 was with the same map but with the fuel scalar adjusted according to the cobb table for an E25 mixture. I think the first one looks better before I adjusted it?

What do you guys think in general? I dont have any logs on regular ACN 91 to share, but hopefully the info in these logs is enough to see how the car is running.

Thanks for your input to anyone who takes a peek!

LOL you're struggling to get these logs posted bud, make sure you set the google doc to "public" I think it's called, it allows anyone with the link to view and download the spreadsheet

what's wrong with attaching a .txt or .zip?

+1, easiest way to do it. just put in an extension that the site has no problem with. anything would work, it doesn;t have to be a valid extension

I'm sure the question has already been answered, but I didn't find it
but if I install a COBB AP on an already tuned car, does it save the whole configuration (including the previous tune) ?

I want to be sure It will re-install my previous tune (saved by the Cobb) when uninstalling it.

I'm sure it does, but to be safe just email COBB customer support. I'd hate to see you lose your tune.

I already posted them in .txt and it is not a readable format because the top columns dont line up... Cant use zip because the damn shysters want $30 now... I guess I could pay it and call it a day, but this is literally the only thing I'd need it for so seems like a waste

I'll try the google docs again....

Come on 3rd time! Both logs are using an E25 mix with ACN 91. The top log is S1+ Sport - no adjustments. The bottom log is the same map & E25 mix, but I adjusted the fuel scaler using the cobb table. I dont really know WTF i am looking at but I think the first log looked a lot better fuel trim wise.

Any input will be appreciated - as long as 1 day I can get these F'ers uploaded in a readable format!

SUCCESS!!!
Just for future reference you should just reset to the default logging list and add LTFT and STFT(bank 1 or 2.) The list you have here is missing some crucial information as far boost is concerned. Overboosting is semi-common with Cobb and you'll want to be sure you don't have that going on.
However, from what I see everything looks good. Timing is clear of corrections during the pull and STFTs are negative so the DME is actually pulling fuel out.

I noticed that the STFT's were negative in both runs, more in the negative like up to -24.5 on run 6 which is the one where I added fuel to the stock map. So I guess I was right to switch back to the OTS map because it runs rich as is w/o adding any additional fuel.

Side note: It is common to have like a 4-5 mpg drop on the cobb? I went from 20.5MPG or so, to the 16's.

I'm hoping adding the E85 to the crappy AZ 91 oct will help bring the mileage back up. No, I dont mash on it a lot more than I did before the map, I actually used to go WOT a lot more often and now I feel like im driving miss daisy because I only need the top 1/4" or so of throttle lol, and driving it like that I get 16 MPG. As opposed to always mashing it on the stock map, and getting 20+

Do I just have unrealistic MPG expectations?

I just did it and it works fine. see attached. Just rename by taking off the .txt

point is not to convert a csv to a txt... it is just to fool the system to think that it is txt so it allows you to upload.

we all know that it is a csv, and will revert the extension back. it will alleviate your pain in the future

Adding E85 will most certainly not improve your gas mileage, it will make it worse. Log looks pretty good though, but like Aenema said, you should include trims and HPFP+LPFP PSI throughout the pull when running ethanol. I wish my car was providing enough fuel for the DME to pull some out, that's solid.

yes it's common to get a MPG drop, especially since you just got it. you are heaver on the throttle . Once you get it out of your system you will drive more normal and your MPGs will go back up a bit. But never like stock. It's a performance tune = lower MPGs.

try getting 15 mpgs as a DD. W/ E50 (50% Ethanol), the fuel is less dense so you need more fuel, but its cheaper than 91. Its about $3.30 for E85 Pump and about $4.25 for 91. about 7.5 E85 pump gallons to 6.5 91 Pump gallons at each fill up right at "low fuel light" it works out to about the same co$t$. but more fill ups.

i dont think it will recognize it so it will save a generic file. Basically you will loose it.
Not 100% sure though. which tune? GIAC? DINAN?

I was wondering the same thing because I am installing the AP and have a GIAC tune now. It says in the quick start guide, which can be found online, that it saves and recognize a couple of different flash tunes that may already be on the car. The n54 accessport recognizes PPK, Dinan, GIAC, and some DimSport flashes.

Hope that helps!

Aenema, if I try to add what you've suggested to the base list,it tells me I have selected more than the dme can communicate. What should I take away?

I yanked out CAT, and I think WGDC. FWIW. Both are useful, but for the purposes of this particular data log I was comfortable pulling them out.

Thanks. Will I only have to remove two?

If you use the default list you should be able to add two more channels to log. So you can add STFT and LTFTs from one of the two banks but not both.
