Okay, I just spent 4 hours straight searching on the forums / google. I read pages after pages about people saying they are excited for COBB and can't wait to try it ETC.

I never once saw anything written up as to why or how it truly out performs GIAC or the piggy backs?

I have however read that people running COBB have power surges and the car lunges forward for 1 - 2 seconds after they let off the gas??
I have also heard there is a surge in low end torque and boost sometimes peaks at 17 - 18 psi??

I also did a great deal of reading about the stock turbo's and what our engines can truly handle before the turbo's start to wind and we need a re build.



Can someone please state why COBB AP is now the top tune? How it is better then GIAC??

I have 2 more days to Decide if I'm having my tuning ship run COBB AP on my car, or GIAC stage 1 on my car.

What are the Torque gains for both, what are the HP gains for both
How does it feel when I'm driving it?


I have read it is simple to re flash your map back to stock with the COBB, is it controlled by a hand held? or do I need to plug my computer into something, * I have an old mac and am not computer illiterate *

I do not plan on adding additional bolt ons for another year or two so I'm not currently worried about the offering of Stage 2 tunes.


Again, Why Cobb AP?? Even after all of the issues I have read?
How much more power does it put down over GIAC, and why does nobody even mention GIAC any more? I can't find any threads about GIAC Stage 1 and people talking about how good it is, why is it no longer liked any longer?

Yes, Cobb has a handheld device and this is what makes it extremely convenient. When/if Cobb will sort out the map problems, it will surely become a favorite among the N54 world. But one question is, how long it will be until Cobb will have perfect driveability and an "install and forget" reliability ? Could you spend one year or maybe more doing updates and hoping that the current problems get solved by the current update ? There is quite a bit of reverse engineering and hacking involved in creating good N54 ECU map. Some problems may take many months to find solutions for.

Giac is a flash tune that requires you to go to Giac specific dealers for a tune. It can only go so far performance wise.

Cobb is a handheld flash tune so you can do it at your convenience, not to mention you can sell the unit when your done when you cant sell Giac.

Last but not least Cobb will have the potential to tune to your specific mods via protune, and ATR tune when they come available soon.

I believe the price point is even cheaper.

There really arent an issues if you think of how many thousands have already been sold in such a short period of time.

The 07 hiccups are will be gone soon enough.

Go to Cobbtuning.com they have dyno's on numerous cars including other tunes besides their own.

I have an 07 335i and installed Cobb like 5 days ago zero issues here. I did have Dinan stg1 prior to the Cobb and there is no comparison the new power is fantastical and scary at the same time.

My big reason going with Cobb is the ease it gets old having to go have your tune re-installed i had to drive 100 miles away make appointments and so forth had to do it 3 different times in 1 year so reason enough for me.

I have read your post on here reference Giac seems you really want that tune so get it. But you keep trying to find people to talk you out of it.

I think, if you just read you will find more than enough info on any of the main tunes on here and just for your info before i went Cobb i was going to go with Procede for the auto tune feature.

I think why you do not find much input reference Giac on here cause it seems to be one of the more least tunes used, that being said i have never heard anything bad about it.

Cobb has great features all at the palm of your hand and great power to boot.

Wow, Very Very Impressive!

Question: Website stated 313WHP on average and 360lb torque
I've seen dyno charts on this forums showing 80WHP gains and 140lb torque gains? Why such a variance?

[vasillalov]

Ok, let me sum it up for you:

GIAC is a significantly better TUNE when it comes to driveability.

COBB is a significantly better overall SYSTEM. The handheld flasher and map switcher is their biggest advantage and overall appeal. It means that you can load firmware and map updates at home.

If GIAC develops something like that, I'll be all over it.

If it means anything to you, I am both a GIAC and COBB customer and I have compared both of their Stage 1 offerings.

You can also see live data, datalog, read codes, clear codes and reset ecm with cobb but you can not with giac or dinan.

[E90Vader]

Thanks guy's. I spent an hour on the website and I'm very impressed as I said. COBB is a fabulous system with so much potential!!

For now I think I will still run GIAC and let COBB continue there progress and sort out all of the little quirks. I may switch over in a year when it becomes the Top tuning option which I know it will for the 335i


Why were the dyno charts so different then what e90 users got? One user said 130lb torque and 80 whp

on the site it says 313 whp and 373 torque?

[Jake@MOTIV]

No dyno reads the same. On my friends dyno you would never see a stock turbo peak over 370whp but on the dyno jet next door I've hit 400+.

I guess it depends what mods every user has. The numbers published by COBB are for a stock car with no mods whatsoever. I dynoed my car stock + DP and COBB st1 + DP (back to back) => I gained 53 whp and 58wtq

Did you try the COBB st1? I have the latest maps so I don't have the 1-2 seconds of push after I release the pedal. I do have the surge though. The surge doesn't really bother me, but that's subjective. Besides I don't think there is issues with tune itself. It is very smooth btw...

If I were you I would go with COBB even now. Just think about it from a cost perspective. If you buy GIAC now, what would you do in year from now? Buy COBB and waste the money you spent on GIAC?

Buy COBB you won't regret it. See if you can find a way to try the tune before you buy it...

[pioferro]

I've had the COBB on my 09 for over 4 weeks now. No issues with surging - no issues at all. I love it! Its foolproof to load and back up and you can have your car back to box stock in 15 minutes whenever you need it.


Their costumer service is awesome.

The COBB dyno numbers are lower than those advertised by other tuners because COBB uses the Mustang dyno which reads considerably lower than dynojets.

[E90Vader]

Will I have to download the new software for 2007 bmw from the site to my computer? Will Mac's even work for this?


- Could everyone whom has COBB and had a dyno please throw up graphs, I'm would really like to see some real world numbers.

Thanks guys!

[deltalima0]

Dude, go to the Cobb website they have a step by step tutorial video for every freaking step. Including updating and downloading software.

There are tons of threads with dyno graphs.

[E90Vader]

I've been trying, I keep only seeing graphs from COBB that show 310WHP and 360 torque. I can't find the dyno graphs other users put up, Ie one that showed 430 torque at the wheels?? with just a dci?

Took me hours to find those this morning and I can't remember where they were. Page 37 or something in one of the massive threads.

[Litos]

my 07 Cobb tune is as perfect as can be.

it made 15 more horsepower and 35 more ftlbs from my JB4.

it made 65 more hp and 92 more ftlbs from stock.

the A/F was an almost perfect 12.5 all the way across the board.

installation via OBDII took less than 15 minutes.

car has never surged under any driving conditions.

tq curve is silky smooth.

i can monitor boost, timing, oil temps, blah blah blah at any time i want.

i can uninstall the AP in 10 minutes and sell it for almost exactly what i bought it for.

i'll NEVER have to remove that god awful air cabin filter assembly and open the damn ECU ever again.

Cobb > GIAC

last GIAC tune i saw was a complete joke. peak tq at 4200 RPMS and the car made absolutely ZERO POWER under 4000 RPMS. i bet that car really sucks to drive.

[O HELLA BMW]

i love my cobb, so easy to install, and the tq down low is crazy, it just pulls and pulls

+1

and just get the COBB!
Its awesome, i haven't experienced power surges either.

And anytime you need to go to the dealer you can easily uninstall it, or if your having your car parked at Valet Parking you can put it in Valet Mode which limits the turbos so they cant mess with your car

COBB>PROCEDE>GIAC>JB4

was your tune also starving for power before 4000 RPMS !?!?

There is a dedicated Cobb AP software package that works under OS X on Macs (as well as a separate Windows package).

See: http://www.cobbtuning.com/info/?id=3059

[Mr. Nice]

Here you go man, this is Cobb Stage 1 and dci. Kind of useless though as as I forgot the accessport itself and therefore wasn't able to get a baseline
It's a great tune, definitely recommend it. The difference is substantial.

[O HELLA BMW]

^wow 332.75hp and 382.69tq with just a dci and the cobb?

i cant wait to see what my dyno number look like
