If I do consider buying COBB I will make sure to always run my logs and check the status, I am just trying to see what other people are doing out there.

Does anyone know what gains the stage 1 drive provides?

I tried stage 1 drive yesterday and it was better than stock but not anything to run home about. Sport was great through. Being that you have an is model, the drive map is prob too close to your stock maps. Don't get Cobb if your only going to run stage 1 drive imo since you have an is model.

That's exactly what I was thinking . Thanks for clearing that up. I am guessing I would get around 350 tq with drive and the IS pushes 330 regularly and 370 with overboost.

I would like to hear anyone else's input on stg1 sport with CA 91. I am trying to have the least possible risk On my engine/turbos.

Stage 1 Drive def won't be worth it on an 335is/1M, like I said try to mix some E85 in there + start running Sport (or Aggressive if you mix for 93 octane). If you're not going to buy/sell your AP b/c of this, I'd say call/email COBB, explain your situation & see if you can get them to tell you when the E85 maps will be released. I'm thinking it'll be close to running the Aggressive tune since E85 is like running organic race fuel.

Thanks for the help ! I will Send them an email and see what they say.

What are the dangers of e85 ? Do you just mix e85 and 91 in your gas tank 50:50? If there is an informational thread on e85 post a link plz!

E85 has the same "danger" potential as any other pump gas -- Don't put fire or a light cigarette near it & you'll be fine. I posted this a little higher up on the page, but it'll answer your mix ratio question. I think if you aim for 93-94 octane mix, your logs will look good with the blend.

Here's an octane calculator that takes into account E85. Just plug in how many gals of 91 + how many gallons of E85 and you should be able to mix 93.

http://www.intercepteft.com/calc.html

**The calculator is assuming that the E85 is of standard value and is equivalent to 105 octane & that the gas you're using already has 10% ethanol. Based on this, a combination of 2 gallons of E85 + 10 gallons of 91 will give you a fuel of about ~93 octane. The 335 gas tank is close to 16 gallons when it's bone dry, so try to do some quick mental math when you go to the pump. There's nothing wrong with doing a 50:50 blend, but since the COBB maps aren't going to take advantage of the higher octane, its a waste IMO to run "98" octane.

thanks in advance.

i paid for mine, did last week. fluid is ment to be life time but i don't agree as there's been a noticable differnce in my car since i changed it. smoother shifts and no more cluncky down shifts. No warrenty as BMW states it's life time fluid. I used whatever bmw use, i am not sure what it is. I advise any steptronic with over 55 000 to look at having it done.

Cheers

Hey guys, this was my first time logging, and I was only able to do a quick pull in second gear. This was on Stage 1 Sport (with CA 91 Octane), after driving on the Cobb tune for about 10 miles... I added a couple gallons of E85 afterwards (not shown in this pull).

Any advice would be appreciated. http://www.yourfilelink.com/get.php?fid=809723

New plugs + Fixed o2 Sensors + COBB Stg 2+ Sport =

So glad that my misfires got fixed, love the power that Stage 2+ provides. Very excited to see what Aggressive is like

This is the only thing that went through my head when I finally got to the highway after everything was installed

So is V4 now definitely out of beta?

I don't think so, just checked the map download page and v4.01 is still beta. Latest full release is still v3.01

Have most of the issues with V4 been hashed out by now? I'm still running V2, even though I've added an IC 6 months ago.

But I haven't upgraded the downpipe yet, so all of the Stage 2s are still out of the question correct? I can basically just go to V3, although I don't know the difference between stock, linear, aggressive V1 or V2 throttle is.

Upgrade to V3. It's solid.

Stock and linear throttle mapping are a choice, but I'm an auto, so stock seems to be the better option for me. Manuals tend to prefer linear I think, but for some stock is a personal preference. The alternative throttle V1 and V2 are only available for stage 1, but I never bothered with them.

I'd just do Stage 1 Aggressive(if you have 93 octane, otherwise do Sport) with either linear(manual) or stock(auto) throttle mapping. You can always return to your older map if you don't like it.

I'm running Stage 2+FMIC aggressive with stock throttle map. It's quite fun.

Yeah, I just update the firmware on the AP, then downloaded Stage 1 V3 aggressive, Stage 1 V4+FMIC sport and aggressive . . . all with the stock throttle map.

I don't have to reload the stock tune first do I? Just reflash with the version of my choice?

I'd recommend updating both your Maps & Firmware on the AccessPORT. I'm not sure how the the v2 Maps, but an approved upgrade (non-Beta) is never a bad thing & will prob get a few more "safe" horses out of the car.

Because you don't have DPs, Stage 2+FMIC maps are a no go, but b/c you upgraded your IC you can run Stage 2+. The different throttle mapping are for personal preference but basically go:

• Stock -- Same throttle set up as OEM
• Linear -- Designed w/ track racing in mind. The amount of pressure applied to the throttle is proportionate to how much power you'll get back (25% throttle = 25% power, 75% throttle = 75% power, etc)
• Alternate is for MT users who had trouble with the Stock mapping

He cannot run stage 2+ but the v401 beta stage 1+.

Yeah, that's what I'm installing right now. Updated the firmware for the AP, then downloaded the maps I mentioned above. Should be interesting going from V2 93 octane to V4.01 Stage 1+FMIC.

Hopefully there won't be any issues. I have the AP still loaded with the stock tune and the V2s just in case.

I have 93 octane available but how safe on the turbos is it? I'm running stage 1 sport now. I want the car to last long

You can run Aggressive (data log to make sure the quality of the 93 there). Run Sport (or even Drive) as a DD Map if you're super concerned about reliability & longevity of the car.

I run Sport as my DD, but for Car Meets & the weekend I run Aggressive and love the surprise from that extra bump in power

[fireline43]

That's sounds smart benzy, I'll stick to that

[Jake@MOTIV]

If you guys like the aggressive maps wait till you fine tune it to your car and can run the values your car wants
