I've never used the datalogging feature before and want to go do some logs to post up, but just wanted to know how I should datalog correctly..
Do i have to do it in a specific gear? from certain rpm to certain rpm? WOT? (the video from Cobb doesn't specifically mention that)
Change your plugs.

That log looks fine. Timing looks great. There is some very minor overboost but you probably can't even feel it.

The fault codes you posted return these results:
2DEC power management, battery control
2AB4 DME, internal error: RAM-checksum

I can't find the 2FCA and 2FDA fault definitions.
I recommend to clear the codes and see if they return.

Thanks for the responses guys!


Okay i cleared the codes and will check again after driving around a bit.

the 2AB4 DME, internal error: RAM-checksum ...anything to be concerned about?



And as far as the shuddering goes. The spark plugs should take care of that?

I posted this log to the N55 section but I received no responses. Can anyone tell me if this log looks OK?

I'm comparing Cobb and Dinan and I had a few questions. I know they may have been answered in this post but forgive me for not read through all 385 pages

Does Cobb V3 adjust water pump timing on the N54 335i? I read a few older posts (2011) that said it doesn't.

Are there a different set of tunes for us in cali where 91 is the highest pump gas?

Long term mods for my car are exhaust and intake (done) and future FMIC thats probably it. I have to smog so I don't want to do anything that takes more then an hour to reverse.

With these mods what OTS tuning options can I safely run DD with 91 pump? If I can only use Driver than it doesn't seem worth it to me.

Lastly, I know Dinan and Cobb are different in many ways I'm not asking which one is a better tune.

With intake + FMIC you can run the Stage 1+ FMIC drive map. It provides a very good boost in power over stock.

I didn't know they changed it to 91 per allen@PTF but based on my testing I had to add a bit more to compensate for 91. So maybe you do start with the recommended and see how your log looks. Remember 91 isn't the same as ACN (Arizona Cali Nevada) 91. We Californians like to do things differently.


Use below.
Just out of curiosity, why did you change the octane value for e85 from 105 to 96?

With the fuel trims being as high as they were on my logs from blending 5 gallons of E85 with 11 gallons of 91, I'm inclined to believe the 105 rating vs 96. Either that or I really need to upgrade my LPFP.

Thanks Allen. So, Cobb still doesn't increase water pump? Maybe I'm asking the wrong question.
Does Cobb do anything to help the car run cooler?

DCI suck balls big hot air balls into your motor and slow your car up. Buy a cheap 50 dollar drop in filter and your good. DCI are only good for noise makers. if you live anywhere warm they suck.

Hi gents. I was just wondering if anyone could help me locate a standard rom file for my n54 135i

The car was already flashed, and now after adding cobb I have lost the cruise control function, and I've also got an emissions error code (this may be unlinked)
Here is my original thread: http://www.1addicts.com/forums/showthread.php?t=973723


I have emailed cobb directly but had no reply. I may be being a bit impatient as it was only Thursday last week (I think) when I emailed them.
My cobb request is https://cobbtuning.zendesk.com/hc/requests/48434

Question VALET MODE

Hi guys.

Newbie question......

I'm being relocated (MA to SC) and my company is putting my 335i on a transport. Might be ~14 days in transit.

I feel I should use my COBB device to put it into VALET MODE.

Is that pretty simple?

And simple to put my custom tune back in once I get the car back?

thanks in advance, Kevin
