Usually the people who actually try the things in question comment on them, if they havn't tried it and still comment, then no troll potion will work.

Cobb AP installed - thanks Jeff!

Ordered my Cobb from Jeff @ Top Gear Solutions on Monday. Received and installed it last night. Very impressed! Thanks Jeff, for the great customer service!

Stage 1+FMIC shortly (very shortly) after that

You know what's funny? People are giving high praises to Cobb which are mostly well deserved, but ONLY a few of us have actually been able to compare GIAC to Cobb. I wonder what will some of the people who switched from piggybacks to Cobb say when they drive an FBO GIAC Stage 2 car...

P.S.:
I know from personal experience the difference between Stage 1 on Cobb and GIAC... Cobb is like an unrefined moon shine: it gives you the kicks but its a bit of a wild ride (throttle closures galore) as to where GIAC is more like a fine aged scotch: not as powerful but has outstanding drivability on the street and on the track.

So assuming there will be some hotter maps with Stage 2, how do you guys or how does Cobb plan to integrate meth for those wanting to run one of these maps on a daily basis without filling up with 100 octane? What sort of "failsafe" features will be implemented?

I still have a meth kit sitting here, just haven't felt the urge to slap it on yet.

Well you're analogy is how i felt going piggy to cobb. So GIAC sounds amazing. If only they could provide it in a cobb like package.

WHatever dude. I have zero throttle closures with COBB on every map that I've used - on two different 335xis. I've got a stock car now and no troubles. I don't disagree that some experience throttle closures but I would bet anything they're caused because of breathing mods or some mechanical issue and not the tune.

I have zero throttle closures as well. The only thing they need to work on is making it more linear.

So check this out:

Running v3.00 firmware and 93 octane map. Cruising normally on 6th gear on the highway on my way to botanical gardens. All of a sudden, there was a pop, the engine went into limp mode and the brake light came on the dash. I pulled over and with the engine idle-ing the rpm needle was wobbly - going down to 400 rpms and jumping up to 1000 rpms.

I shut off the engine, I popped the hood, inspected all the plumbing I could see and everything was normal. I started the car back again and everything was fine.

Came home, plugged the BT tool in and I pulled the following information out of the ECU:

Quote:
2D59:
2D59 DME digital motor electronics, internal failure: control actual torque??
Error will cause a warning light
Error is not currently present
Test conditions have been completed

Freeze Frame Information
Event 1Odometer 38488kms 23915miles
speed control 3,264.00 rpm
motor torque nominal value control 364.00 Nm
motor torquet actual value control 508.00 Nm
nominal value motor torque 0.00 Nm

Note the major difference between the nominal and actual torque values.

I don't know about what you think or believe, but Cobb has some serious work ahead of them.

Funny you say that, but there are ZERO users reporting problems with GIAC software. When I had GIAC Stage 1, I had the EXACT same mods as now and the driveability was fantastic.

You do realize what caused this though right? The throttle in not linear, in some cases going 50 percent throttle in a high gear will go wot, no one wants to ever load up a car like that.

You want to start listing where GIAC needs improvement? Cause that list is alot longer

1. It slower
2. You can't install it
3. You can't log with it
4. You can't clear codes with it
5. You have to pay for additional maps

Like I said many times, personally i dont care about staged maps, the only thing I personally care about is the release of ATR

+1. Glad you are liking GIAC but you got ripped off. When ATR comes out and all of our cars are running better/faster than yours then you will want to sell it and get Cobb. Oh wait...you can't. Oops. That money is gone forever

So add #6 to that list: Resale value. I bought my cobb for $750 and I'll probably sell it for $700 when I'm done

Dude, save it. I respect your technical knowledge and the amount if info you are contributing here, but I think you don't know what you are talking about.

I was CRUISING in 6th gear. Not accelerating, not slowing down, I was maintaining constant speed. How much do you need to press the gas pedal on your car to keep it cruising? On mine: barely! That's not even 50% throttle. Probably under 20%. Shiit, the car idles at 11% throttle angle.

Cobb:
1. Poor driveability on the track. Impossible to modulate the throttle correctly when coming out of a corner. Imprecise power delivery and boost control.
2. Lots of people seeing throttle closures.
3. Lots of people seeing DTCs and all kinds of other weird issues.
4. Can't switch maps instantly. Must turn off engine.

GIAC:
1. Yes you can log it. Use a BT tool and it logs everything for you.
2. Yes you can clear codes with it. Use BT tool to do everything you need.
3. Instant map switching with the hand-held switcher.
4. ZERO, ABSOLUTELY ZERO complaints from every single GIAC user.

In all honestly, so fucking what that GIAC is bit slower than Cobb!! It's driveability is MILES above it. When it comes down to driving on the track, I am willing to bet you anything that a good driver with a well sorted tune will perform a lot better than the same driver with a choppy unrefined tune.

When are you people going to learn that 1/4 mile runs and dyno numbers DO NOT tell the whole story!

Umm why would you want to sell something that works not just well, but it works GREAT?

Are you leasing your car perhaps?

1. Using a BT tool to log Giac, is not Giac logging btw
2. Same
3. What did that cost you again?
4. Its slow, Ive also seen like 2 logs in the 3 years it has been out.

If you preach GIAC, why arnt you running it then. Put it back on your and stop complaining about the same shit in every Cobb thread.

As far as cobb issues, these recent internal dme codes were all on v300 which is already solved by cobb. The reason you hear so much more about it is becuase I would bet my ass on the line that cobb tuned cars outnumber giac tuned cars 10 to 1, and cobb has been out for a couple of months. You want a real tune, sit back and wait, you want to bitch and complain, put on your Giac tune and be happy

Clap,

Yes, GIAC does cost more. I paid $800 for Stage 1. In my opinion, given the alternatives, it is worth EVERY PENNY!

Why I am not running GIAC: that's simple. I've said it many times openly and I will reiterate it again for 100th time: GIAC absolutely drives me up the wall with their method of installation. The entire visiting a dealer, getting a read file off the ECU, waiting on GIAC to produce a flash file for your ECU, then the GIAC dealer installing it on your car is absolutely ridiculous. Last time this happend, it took GIAC 3 months to come up with a flash tune for my ECU.

It is BY FAR, GIAC's biggest fault and problem: dealing with their dealers for reflash. It takes time, it costs extra money sometimes and it is annoying. I admit it and I am constantly telling everyone about it.

However, just like I tell everyone about this fault, I make sure everyone knows the comparison between Cobb and GIAC, because I own both!

Listen, to end this Cobb vs GIAC discussion: I have no horse in this. I own both products. I only care for the tune that will perform CONSISTENTLY the best on the street, on the track, in the winter, in the summer. It does not matter to me which flash tune this is.

At this point in time, Cobb is seriously lacking compared to GIAC, but it has a lot more potential. I bought it because it has potential to become something truly remarkable in the future. At this point in time though, it is just mediocre.
