ATR is the user tuning software that COBB provide for free. You can go to their website get it. Fuel scalars basically will set the ethanol content of your fuel mix so your DME can adjust the volume of fuel to inject accordingly.

With that said, the DME has some freedom to compensate, so for stage 1 agg and a low mix if E85 you should be OK.
Mix in some E85 and log You will definitely feel more power with E85 on the same map just because timing won;t be reduced. Do a before and after log

Whats the best way to upload a excel spreadsheet with the data? I just did a few runs. I don't even know how to upload a picture here. God I feel so stupid suddenly.

I also went to Chevron and put 2.6 gal of E85 in so it comes out to a 93.2 Octane mixture at the moment.

Basic question; what is the simplest way to get "inmersed" in this COBB jargon and "how to" data logging? I am mechanically inclined and will pull the trigger on COBB within days, currently have Dinan S2 but I finally have decided to take the next step.

Basically- seems like everyone recommends datalogging especially immediately after install I guess to ensure everything is running smooth. I am sure i will eventually learn. I'm just worried that the time it takes for me to figure this out will be a crucial time where the car may be telling me something critical on the datalogs and I don't catch it until a couple of weeks later.

I'm I just freaking out or is this legit worry? Millions of post here, if anyone can shoot me a good url where to start and critical basic know-hows, I would appreciate it! Thanks fellows, this site has really helped me alot.

There is no need to log if you are using the right map for mods and octane. if you for example always use 93 octane go with aggressive one or if you want to be on the very safe side just use the sport map till you figure everything out mostly by Searching here.

I had originally posted this on another forum but havent gotten much feedback..

Just installed a VRSF FMIC, feels great and did some logs wanted to have you guys take a look. (rename the files from .txt to .csv)

2nd and 3rd gear pulls (AT) traction control all off.

Mods are CAI, BMW PE and of course the FMIC and Cobb v.402

Thank you much.

Thank you much.

Timing looks great in the first graph but a couple corrections in the second graph. Unfortunately you're having some over boost related throttle closures. Search the forums and you can find a fix for it using ATR.

Thank you!!!

I am not an expert, but this doesn't look too smooth huh?

COBB Stage 1 Aggressive LT on 91 Octane....

[Ænema]

Nah, that doesn't look too bad. Boost is under control, looks like you had a timing correction during the shift but it doesn't look too severe. Post up the .CSV file as a .txt and it'll be a little easier to review

So I ran this previous one in the post above on 91 California Octane... If it's not looking bad, I don't know why everybody is making such a big deal out of it.

Here is another one with some E85 mix to 93.2 Octane. Looks similar to me. But again... I am a newbie

And again... all this is on COBB STAGE 1 AGG LT map.

[Ænema]

That one you had some boost overshoot at the start of the pull and during/immediately after the shift. During the shift a small amount of overshoot can be normal.

You only had a couple timing corrections, one was during the shift and the other was while the boost/load was ramping up. Neither of which are a huge problem.

EDIT:to make more clear

You only had a couple timing corrections across all 6 cylinders, one was during the shift and the other was while the boost/load was ramping up. Neither of which are a huge problem.

So what is the conclusion here? Can I continue running the map without any issues on 91 and/or 93 octane?

thanks!

Yeah, you should be fine.

[Jeef]

so still get code p2a9e, and p2a9f. its not the solenoids i cleaned them and replaced them with new ones. any know what else it could be?

[Boostin335]

Can I run Stage 1 Agressive map on 2008 535 xi with 93 octane and BMS panel filter?

Also can someone tell me difference between stock throttle and linear throttle ?

Yes you can.

Stock is the same throttle response you are used to.

Linear has a more linear response -> Load/boost is linear with pedal input

Try them both and decide which one you like more

[Jeef]

anyone know anything about my question? thanks.

I tried searching for bud, very little info. One guy had a blown fuse.

Another guy mentioned something regarding the crankshaft sensor. Personnaly I have no experience with your issue. this is all I could find.

Hi all,

I got a Cobb last week and I got a really good deal on some custom tuning by Neetronics.

And I must say that it kick ass!

My car is a 2011 335is coupe, bone stock and I was running 94 oct, and I really can't believe the numbers they got with the custom tune.

But I seem to have a couple of problems with my car now.

1) When I try to use my curse control is reading - - - and does not work

2) And my service interval was reading 20,000km because I had an oil change a month ago, now it reads (-100km).

Has this happened to anyone else? If so what is the solution to my problem.

Thanks

[jayzF30]

That looks like Cobb OTS Stage 1 numbers to me or a bit less. I would expect considerably more out of a pro tune

I think it says that because you're swearing too much in the car.

Losing CC functionality was an issue a while back for some users. Try updating AP firmware and then reflash the car.

As far as resetting the service interval just Google "resetting BMW 335i service interval" and you'll get several step by step instructions on how to do it.

Keep in kind that is an 335iS. The factory overboost feature leaves less room for gains when tuned.
