All COBB Tuning AccessPORT Flash for N54 335i Discussion Here

If the maps are changed... Could an accessport for an N54 work for an N55 engine?

When I cleared the codes this morning, the ABS light showed up in idrive and in the gauge cluster during the code removal process. Once the codes were cleared, the lights were gone and the code never showed up in my AP.

I tried clearing a couple more times and each time the ABS light would show up. Has anyone else experienced this?

I saw that yesterday too when changing maps. I think it happened once before. Both times only since the Alpina B3 TCU flash. It clears if you clear codes, turn off the engine and restart.

What am I looking for as far as timing drops go? Is it the actual value (as in below a given degree is always bad during WOT) or is it dips in the timing under WOT?

When looking at dips, what is considered a bad drop? More than a few degrees?

What you dont want to see is a sudden and severe pull in timing. So if youre starting at say 5 degrees, you should see a steady climb upwards. Minor timing pulls happen, but if you see a serious timing retard, the DME isnt liking what its seeing.

i have a question,
im considering doing the Alpina flash for the transmission,
does this in anyway affect cobb?

do i need to uninstall the cobb first, then re-marry it to the car after the Alpina flash has been done?

im thinking it wouldnt affect it either way - but just want to be sure

No.

Alpina is a TCU flash.

Thanks, I'll post mine once I get access to Excel to plot the data.

Did you recently update to the newest firmware? I'm wondering if they changed something during the latest update. Maybe Cobb Tuning can chime in.

You should use my grapher, it will make things easier

Timing drops >3* accross 3 adjacent cylinders are highlighted in red, and 0-3* accross 3 adjacent cylinders are highlighted orange. This way you get a quick glimps into what is going on.

For those taking their car to the dealer for warranty work, are you all flashing to a stock map or are you completely "unmarrying" the COBB from your vehicle? Or are these actions one in the same?

They are not the same. You should unmarry if you have to go in for warranty work.

The only time I have seen this is when on a Dyno.

Its normal. Since I merged the code for the N55 and N54 products, there are extra modules it tries to clear codes on. The ABS doesn't like to lose communication while this is happening, so it triggers a warning until comms are completely restored.

Whenever I uninstall or install my Cobb tune, the buttons (all of them) on my radio faceplate stop working. It happens sometimes when I change tunes as well. Anyone else ever had this happen? Dying battery?

Yes. It might be datalog 16/17 that trigger the codes.
It was at about 5000RPM when the codes came on.

Sorry I dont know how to read the datalogs.....or what they means.

please read up on how to do a proper data log it will help your cause greatly.if I had the link I would post it for you but I don't sorry. only thing I saw was some pretty good throttle closers and some pretty good timing corrections in another .

USCTROJANSFIGHTON · 08-08-2013, 09:23 PM

Okay. I read up on it.
Disable DTC.
Rev to 2500 RPM
Hit start
Floor it until the half engine light on.
Let off on the gas.
Hit stop

Here's what I got:

No other modification to car
Stock.

Is it common for Boost Leak to occur on DRIVE map?
That means i can go higher than 4000-45000 RPM with triggering this CEL?
Thanks
