yes, the ecu will adjust exactly the same way it would without a tune.

the bmw ecu is very good at protecting these engines.

Yes I stick to top tear gas, but if the octane isnt there for the 93 tune for whatever reason. I wanted to know if the tune/ecu would help the issue by pulling timing. I think the Vishnu Autotune would do this but I wanted to see if cobb would too.

What I would do is either switch to the 91 map or stock map, at least until I could fill the tank up with better gas. I used the valet map and it took all of 30 seconds to switch...that's pretty cool.

On a stock car or a remapped car, the ECU is constantly (and better than any piggy back can be) monitoring for poor conditions and adjusting to prevent damage. Run logs, watch your timing and boost for the gas your running and you will be fine.

Everyone thinks the piggybacks are doing something magical to run safe, which some are doing to a point, but the bmw designed ecu logic easily trumps these and prevents even the worst designed piggy/tunes from blowing these engines up.

To answer your question clearly, yes the ECU (stock or remapped with cobb) pulls timing under poor conditions, its been supported by several logs provided over the last couple months.

That is what i'm looking to hear. Thanks.

just ran stage 1 91 oct map with FBOs.. feels great! The power is lacking vs. JB3 2.0 map 3 but thats expected.

Can't wait for stage 2 FBO maps!

Done ... and "FUN".

Hi Cobb,

Any update on the ETA for AccessTUNER Pro?

EDIT: The reason I'm asking is that today is the last day of Q1 2011

[e92OCD]

I've had the Cobb installed for a couple of weeks and just wanted to share my drive home last night.......
I'm cruising along and see an Audi Charging up in my mirrors. Not sure which model at this point as they all look the same from the front I dont feel like moving over so I drop it into 4th and have no problem staying in front and eventually pulling away. We both stay on it long enough to verify that the speed limiter is definitley removed............
At this point I'm also certain that this isn't an A4 2.0. I let him in front to see what I'm dealing with and see that its an A6 4.2 V8. After a quick look I have no problem passing, and trust me he was trying!
I know the audi is a bit heavier and wont win any drag races, but the V8 puts out an underrated 350 bhp, and would normally pull away on my stock 335i.
So just a mental note that stage 1 Cobb can handle any Audi product shy of the R8, and maybe the S5............ Unless someone has an S5 experience to share?

My guess is that the only potential stock Audi fight would be any of the RS models vs. a 35 w/ the AP alone. There's video already of a stock 335 taking out an S5, and I've had multiple experiences with the V8 S4 with no issues. Now the new supercharged S4 is a different story - stock, you won't have a problem. Modded, depends who spent more

Nice kill dude. I think we are all eagerly anticipating Stage 2 so it won't even be a contest.

When AccessTUNER Race is released, will it have an incremental cost associated with it beyond that of the AP or is it a "free" add-on?

You will have to pay a license fee or other combination of fees to Cobb as a tuner for the software.

As an end user, you will have to pay your tuner to custom tune your car.

EBIT: ATP is the vendor version which costs money. ATR is the end user version which on all platforms is free.

Ahhh ok - thx - post edited

Just installed Stage 1...wow! Power comes on quick and lasts!!...I am very happy with the COBB AP product. Chris and Turtle were great to deal with as well. I purchased it from MachV.

I've got a Vanguard exhaust on it as well....great combo!

Installed the access port last weekend on an 08 E90 335i and the power is incredible. However, a couple times I've had the auto transmission just completely miss the downshift under heavy acceleration. The revs just go on until it's bouncing off the limiter. Then once the revs get to 3k or so, the trans shifts. I've only seen it under WOT acceleration. Anyone else see this problem?

[JABM]

I apologize if this has already been covered elsewhere, but I didn't find the answer after a few searches and I don't have the stomach to read all 52 pages in this thread again, let alone all the others.

My question is: Are there any code scanning/clearing cababilities that a BT scan tool has which the Cobb AP can't perform?
My understanding is that the Cobb unit will show you the alpha-numeric code itself, but not what the code means. Aside from that though, are there other limitations as well that would make a BT scan tool relevant to those who have the Cobb AP?

Weren't there some problems with the AT that the updates were supposed to take care of?

I've downloaded and installed the AP last Tuesday (3/29), I assumed that was a newer version. The AT (Steptronic) works perfectly normal.

BT tool has more diagnostic capabilities for other things. There is a large list you can find on their website.

The Cobb has the ability to read and clear codes though.

BT tool isnt 100% necessary on a regular stage 1 car, but I'm glad I bought it for a couple misc things throughout the year. I like having full control.

[blacknbean]

can the cobb read/clear codes without being installed? or does it need to be fully installed to work?
