I haven't seen the kit.. only the pump. I have no problem putting a fuel pump in but am a bit nervous about splicing wires in my fuel tank. Do you have a link or know where I can find info on the complete kit? I have just seen BMS's DIY using the Walbro pump and various connectors, hoses, etc... Once again... thanks and I am loving the ethanol map... other than this hiccup. lol

Yeah, i guess i shouldn't have said "kit." As far as i know there is no vehicle specific kit, it's just special e85 connectors that still require splicing. If someone were to release connector adapters specifically for our cars i'm sure they would sell like hot cakes...

Any turbo car that I have driven had vacum more way more then what my log shows. If anyone knows let me know.

FYI - contacted COBB about this and they replied that this is normal under the new firmware so don't stress if you don't see vacum reading.

Is IKBOS IS the onle 335IS map available?

First post ever in my life.

Wife gave the nod for getting a used 335i the other day. On a minimal budget. Found a clean 2007, with the options I want, but then read somewhere about how 2007's can have more problems when tuning than the 2008's. I called Cobb on Friday and their rep recommended I look for a 2008 or newer. If it is just a small difference between the two, then I'm ok with that (due to the awesome offer I have on the 2007). However if the difference is such that once I tune the 07 I will have more problems than if I tuned an 08+, then I will wait for a good deal on an 08.

The max engine tuning I would plan on getting is the stage 2+ with the required supporting mods. I know the 07 sport option does not come with an oil cooler, but I found an FMIC/OIL cooler combo that would probably work (being that I would need the FMIC for stage 2+ anyways. I also like that with the early 2007 automatics the rear end is bolted making for an LSD cheaper.
That being said, my main question is 07 or 08+? However, any supporting info would be much appreciated.

I bought a fairly low mileage 07 a year and a half ago and its been tuned for a year. I love the car. Only issue i have had is 1 coilpack went out on me. That happens to all n54s regarless of year. Btw...If it has the sport package then it DOES have an oil cooler. I would just make sure all the recall work has been done on it and have it checked over for leaks etc... however I would do that on any used vehicle. If you have a great deal I wouldn't be scared of an 07.

With an older model year you may have a little more maintenance work/money to spend initially but that's to be expected. There are TONS of tuned 07s running around because of the great prices they are gong for now.

@pylepilot
I had my tuned for a year now. No issues. My pro tuner actually complemented on the performance. Most likely due to low mileage. But there are horror stories of 07'. Especially in their DME failure, I fall under the build dates where the DME just fails, but so far so good.

If I were to decide I would go with the 08'. If I am not mistaken, I believe the idrive is a bit more sophisticated, mine is pretty generic. This is of course you have this option. But the idrive shouldn't be deciding factor. .

But you are on the right track, know your goals and pick the right application.

And yes 07 have the bolted diff. And yes my car came with the OEM Oil Cooler. It was the early 07 and 06 I believe didn't come with oil cooler unless the sport package. Not exactly sure, but easy to find out.


Oh and S2+ is where you draw the line.. Bwahahahahahaha..... The Bug will overcome you.... ProTune...E85.....Upgraded LPFP....

Hey guys, I recently just got my first 335, and am looking at the Cobb tune, or the GIAC tune. The cobb is sticking out to me because of the install ability. I live in Arizona so I am limited to 91 octane gas.

1. Ive heard the Cobb runs alot of boost, is it safe for our turbos?
2. What maps come pre-loaded on the Accessport when you buy it?
3. Any comparison between smoothness and power of Cobb vs. GIAC?

I've thought about the boost too but I believe stage 1 aggressive doesn't even go past 18psi which means you should be fine for a little spirited driving. I was running non FMIC stage1 aggressive and loved it as a DD. I've only since had problems (not cobbs fault lol) trying to get an FMIC on my car.

Maps on the car come with enough stock maps to get you all the way up to meth+ downpipes if I'm not mistaken so lots of room to grow just on the stock maps (and pro tunes will take you further)

Cobb if you feather the throttle you could run without ever knowing it was on the so very dd driver friendly in my op.

Tons and tons of info on Cobb and GIAC

Generally speaking I find the Cobb maps lean towards more boost as opposed to more aggressive advance, that's a general statement so don't take it as end all be all. I can't comment much on GIAC though i've read they generally run more timing (grain of salt, I don't use GIAC), but GIAC is well known and has its fair share of users here. TBH I don't remember what comes with the AP, but downloading new maps takes like 5 minutes, so it's largely irrelevant.

When it comes to boost and "safety" it's much more about how things taper, as opposed to peak boost. Stg2+ agg will boost about 18.5psi or so midrange, it tapers pretty strongly down to 12.5 or so approaching redline. Doing that allows cars in all scenarios to be run safely. So in short, yes the OTS maps are all "safe" for your car. Now if you're constantly flogging your turbos for tens of thousands of miles, there's no doubt in my mind they'll wear faster. But that doesn't qualify as "unsafe" in my book, it's what you should expect when you push these snails hard.

Not all early 2007 with sport packages have the oil cooler. Need to look and see if it has the oil cooler.

on 4 out of 6 logs my S1+ Agg. hit 18.0x and a couple hit 18.2x at peak boosts 38xx RPMs. nothing to worry about.

right, that's what I meant to say.

Fedex tracking confirms my Cobb will be delivered today I am so stoked. Will post some logs later so you guys can give me some advice.

and you will receive great help.

my only suggestion is to post the actual csv log file

read this thread:

Enjoy your new tune!

oh and also post MAP with supporting mods and Fuel.

I have searched alot, but am looking for a more up to date review. Since I only can run 91, is the drive, or sport maps the ones that I am supposed to run? I am worried that I will cause detonation by running the aggressive maps on 91 octane

I'd run stage 1 if you've been on stock as you'll still say HOLY S*.

Having spent close to 3k with cobb I'm 100% confident that as long as the battery doesn't die while I'm switching maps/ I don't play around with things in the custom maps before I've really learned it will be solid as a rock for many miles.

Try stg1 sport, let the car adjust for a bit, and pull a datalog then post it up here. Your car is not going to have serious knock on stg1, it’s just not very aggressive mapping. Just gotta experiment and see how aggressive you can get with 91oct before the log gets too messy. If you have any E85 near you, you could mix in a few gallons to raise the effective octane to around 93, then you’d be in the clear to run stg1 aggressive from a fueling standpoint.

sounds good, is it true that E-85 does damage to our fuel pumps?

Yahoo!!! ACN 91!!! sorry bro, your stuck like me.


for the car to be very happy, S1 Drive is your best. I ran S1 Sport, you get some timing corrections, but do a log so we can see.

S1+ Sport not a chance, my log was horrible using ACN 91.



Absolutely not, you can't run Agg. MAPs on ACN 91. unless.... hehe

put in 3 gallons of E85 pump and you'll love it.... YAHOO!!....

Really? Thats surprising considering Cobb says they designed the Sport programs specifically for 91 gas.
