do you think it can be a hardware related issue when it's mostly cylinder 5 timing drop and its every once in a while?

than is fine, see dzenno post. just think about piggybacks where only cyl 1 is monitored.

I don't understand one thing: as far as I know, there are only two detonation sensors attached on this engine. How can the ECU independently pull timing on certain cylinders if there are no per-cylinder detonation sensors ?

Because there are several ways the N54 monitors detonation/knock.
One is the traditional knock sensors, another is the fuel injectors also function as knock sensors and the DME monitors the CPS for crank acceleration and if something is off it is able to determine which cylinder by comparing crank position and firing order.

Cylinder 5 is notoriously "knocky" on my car too.

I hooked up a battery charger this morning and went through the process. Probably didn't need the charger, but just to be safe. I never knew there was an easy access positive terminal under the hood! I'd always assumed I'd need to dig into the trunk to get at the battery connectors.

The process went exactly as described, dash lights and nav screen flicker lots of warnings, during both the save/backup and flash process and everything clears up at the end. No hiccups or issues in the process. The simple instructions are 100% clear.

I've had a few short trips now, probably 45 minutes of driving. After allowing warm up, I let the car adapt without pushing hard for a while. After three quick trips, and a couple opportunities to pass quickly, I am very impressed.

I chose the Stock Throttle, Stage 1, Sport 3.01. I have 93 octane, so I'll switch to the aggressive map soon.

I don't think this could be more polished or painless if it were offered by BMW. This fits my needs precisely, real power increase without fuss.

Nice job Cobb. I'll post again as I learn more.....

mj6234 · 03-09-2012, 12:48 PM

Get the Beta v400 maps! They are a step up!!

Phantom 335i · 03-09-2012, 12:53 PM

I look forward to being able to flas my car to the V400, I really feel my car lacking power down low

Enjoy the car

log a couple of runs to make sure everything is in check

nittany · 03-09-2012, 01:03 PM

here's my very short review of the v400 map, it's a combination of stock throttle map and linear throttle (like somewhere in the middle). the power is there when you push it, however it's so butter smooth with normal crusing. it's nice to know this v400 has more power from the previous maps too.

i had the ap since day 1 when they came to bmw scene and i have to say v400 is the best one for me so far.

good job Cobb!

Is that what I have here, or is this just mistiming introduced to impart a burble and rortiness into the engine note? The engine became naughtier sounding a few years ago when my WG upgrade was done and I'd assumed that some new bmw software deployed at that time introduced that, but this seems to be a COBB thing too.

Anyhow, no codes or anything, and otherwise happy.

See attached for a various second and third gear pulls.

Is this normal?

Cheers
Chris

P.m. forgot to add, keen to know before I start chucking LSD and suspension onto the car. Cheers

Hi. I would really appreciate your view point of the logs I attached. They're not the cleanest but I don't want to trouble Cobb themselves if there's nothing wrong and I don't really know what I am looking for.
Thank you

edit: added some 'cleaner' logs with comments.

Smokn944 · 03-09-2012, 02:46 PM

Thanks for the quick replies after my thermostat issue, the codes p0128 that appeared while running my cobb tune turned out to be a stuck open thermostat. While 2 weeks ago the electric water pump went. BMW went and changed under warranty. So Cobb is getting reinstalled later today.

am I the only person having a hard time finding the v4 beta maps?

Hey Rob, i sent you an email a few hours ago... Please check when you get a chance, thank you!

I also can not find the BETA button..??
But here is a link i found a few pages back.. http://www.cobbtuning.com/AccessPORT...aps%2Fbmw-grid

Simon76 · 03-10-2012, 01:36 AM

I'm sure that there is no red beta button on my screen..

There is no such button on my screen..

That's because there is no beta button when you're on the beta page

The link you provided yourself a couple posts back is the beta link. If all the buttons for each ECU type are red, then you are looking at the beta maps.

Simon76 · 03-10-2012, 03:01 AM

No No.
When i click on the link provided by Robb, http://www.cobbtuning.com/BMW-Access...s/bmw/bmw-grid
there are blue ecu-icons.
And no red BETA button.
I have tried a hundred times. Starting on there homepage, or clicking the link above.
No matter i have the direct link, but it´s very strange..
