No, if you plug in th AP and scroll down to the "uninstall" feature, there will be no tracing left whatsoever of the tune.

It's been over a few months since the N55 Cobb tune was announced for development. Is there any news on this product yet?

[jdlana]

Bought Cobb last week and luvin it. Great support from Cobb, great help from Jeff@topgear, great product. I'm an excel guru (more than a car guru, actually), and I'm looking for the decoder ring to all the datalog fields. I mean, am I the only one who doesn't know what WGDC % is, or the difference between TPS act. and TPS req?
Can someone post a datalog primer (or show me where one exists)? I'm tired of plotting timing and boost vs RPM and 0-80 mph graphs.
Thanks.

WGDC = Wastegate Duty Cycle

TPS Act. = TPS (Actual) or throttle blade angle

TPS Req. = TPS (Requested) or throttle commanded from the pedal


I've attached one of my Excel 2007 datalog + pivot table graps to this reply. You'll still have to manipulate it a bit for your data capture, but it should give you an idea of how we're creating the graphs.

i have a 2008 335I im about to buy a used cobb AP. i just want to make sure i can tune it with no problems correct?

^make sure the previous owner of the cobb uninstalls it, if not it will not work on your car.

thx for the heads up

im just concerned about the warranty i hope theres no way to trace it.

[O HELLA BMW]

if you have to take your car in for warranty work then simply uninstall the cobb and dealerships shouldnt be able to trace it. get a bt scanner , and after you uninstall the cobb check to see if anything comes up on the scanner.


i need to get me a bt scanner just to make sure all the codes are gone when/if i have warranty work.

but bro the cobb is day/night difference, the power is insane from stock, it just pulls and pulls

Hate to be that guy, but Stage 2 ETA?

silence

[Clap135]

So now that all the 07 cry babies post poned everything, will the n55 guys further delay stage 2 development?

+1. Also, I came across Cobb's Launch Control and Flat-Foot Shift for Soobies. Is this something us 6MT guys can expect in the future on the BMW platform?

cobb...can you run race fuel with your 93 octane map or will it even do anything if not tuned for it? if so what fuel/mixture do you sugest?

[Zeph]

Any idea what P2E9F code is for? I also have P2FA3 but I know that just means I am not running stock ECU software... I tried clearing and both come back. I have had the P2FA3 since install (of course) but P2E9F didn't happen until a few days later. I have searched that code and nothing comes up. I don't really see a list for all COBB codes either.

TIA

Cant hurt but wont do much for performance.

The OTS maps are tuned for that octane. If anything it would just ward off any potential knock if you were hot lapping or something on a road track.

I have the same code. Not related to a tune, you may want to read this:

awesome, thanks! I actually drove it a ton today and ran some high speeds. Maybe I will just try to clear it again and see what happens, it has been a few days since it popped up and I just changed the oil Friday (don't think I cleared all weekend)...

[pHo_e92]

anyone know what P2f6c means? found nothing on google...

[Zeph]

FYI, many already know this I am sure but I happened to look at my codes again yesterday. If you scroll down and actually "highlight" the code, it gives a brief description (on the AP). I thought that was helpful as well, atleast for a general idea.

[mithiral67]

Cobb,

Could you guys provide us with a general status update. I understand you prefer not to give time frames as you will be harassed endlessly about them. However, could you give us a quick summary of what you are working on, what stage you might be in, what is on you radar to be the next item to tackle. Thanks
