Do i need a dp fix to run downpipes with Cobb or will the Cobb take care of any codes for me?

Thanks!

While running the AP, codes will be suppressed. If you remove the AP for service or warranty work, they'll be there unless you have the DP fix.

+1 on this....Cobb, the current LC on the 335is is perfect for stock, however after adding power LC is a nightmare trying to launch at 5K rpms.

Is it possible to include an option in the AP to flash new RPMs for LC ? Having various steps like:

Step 1 = 5K
Step 2 = 4K
Step 3 = 3K
Step 4 = 2K

thats probably quite low priority right now for Cobb. If they modified launch control for the GTR i dont see why they cannot do it for BMW.

From what i was told; launch control is on their to do list. Not just for the "is" but everyone with an N54. Even a 2 step launch is on the horizon for the N54. But i doubt any of that is near the top of the to do list.

Not sure if this has been posted in here yet, but EFI Logics in CT had some very impressive results custom tuning their 135:

This car is bone stock, all we added was an AccessPort and some custom tuning in house, and the car picked up 88hp and a WHOPPING 124ft/lbs of torque making a total of 341hp and 394wtq. The car picked up 28hp and 40ft/lbs over the Cobb OTS Mapping as well.

Check one of my posts in Cobb forum. Has excel attachment

Jpsimon: jesus christ!!! That's awesome!!! Is there a log to go with that run? I'm very curious as to boost and timing.

[pHo_e92]

WOW! now i really want to get a custom tune!!.

Hey Rob or Ian, do you know if one of your dealers in Ontario, Canada has the Protuner beta? i would love to go get my car custom tuned.

no that's all that was posted on Facebook. the custom tuned run file says "16psi" though.

[rader1]

I wonder how high in the rev range that 16psi holds? Either they're running aggressive timing up top or they're holding boost taper to a minimum. I'm betting timing.
Either way, the potential is awesome!!!!

EFI is a very well known/respected shop, they do some great work. Can't wait to see what they can do on a fully modded N54.. that 135 was BONE STOCK!

I'm hoping there are Cobb custom tuners in my area, central VA is like a desert when it comes to competant tuners.

[dzenno]

Ultimateracing and neetronics are cobb pro tuners but neither have experience with n54 dme tuning yet obviously

[tscdennab]

So any estimated time of arrival for the new Cobb stuff ? It seems they have deciphered many ECU innards lately and I am curious if they can finally produce maps that no one will complain, no oscillations, no dead spots, etc. And proper meth maps...

I suppose no bog is too much to ask...although this alone would be a reason to switch from any tune to Cobb.

I talked to Cobb and there telling me there's maybe only 20 whp
On pump
Gas left on the table.

Not sure if
It's worth Doing it yet.
I have a friend of mine who wants to protune it for me but don't want to be the first .He got the key 2 weeks ago but waiting for people to test it first .If you think about it ,stage + is aggressive and you still have to remember its pump gas and want to leave ro in case anything .A bad tank of gas good cause bad issues .Cobb told the next firmware there spicing about stage 2+ a bit more .

[dzenno]

That tune is pushing it really aggressive for pump gas, glory run for sure...i'm sure that whoever owns it won't be heavily pushing the car on that tune for extended runs...i agree with the above, you have to leave some room on pump gas to be safe

its like my 471whp pump gas dyno...definitely doable, maybe even higher is possible and I can do a pull on it but i'd rather not worry, run meth and crank it up further or just lower it down a notch to 450, be safe and run it as hard as I wish...

[Streetsweeper360]

Dezenno there looking to make so much power on pump with out thinking of downsides.Lets think about 19 psi peak and 13 psi taper with 9 * up top with stage 2+ to my knowledge ,there's very little left and who knows how many times it would knock when it sees real load conditions on the street .With all the bolt ons completely catless on pump making 415 whp is very impressive in my book.

I was just now looking throught the Cobb site and it looks like the closest place is Mooresville, NC. Ive been to mooresville a couple times with my buddy to get his single turbo camaro tuned at Williams performance and that whole area is a motorsports mecca

And i agree there's probably not much left PEAK power wise, but a custom tune for my mods should still be an improvement. Maybe a 93/E85 mix map while i'm down there...

sorry, no, just my fellow Canucks in southern Ontario

in general, a custom tune for the mods and a particular car should provide more gains but not leaps and bounds...

if I had to guess, basically what you see in the above dyno is the stage 2 or 2+ tuning running on a stock car, rebranded as a stage 1 by the pro tuner...just a hunch

[rader1]

Yeah, i googled those tuners and figured that out and edited my post.

[Streetsweeper360]

Let's see what Cobb with this new map2 + their improving ,there fixing the flat spot am some others things .Always a custom tune is best but the BMW is different from other cars like subarus and evos .The map Cobb designed for us is a bit and beyond a base map.
