Hello everyone, I've been on 6speedonline for sometime now. 2007 911 TT 997.1 6 speed. I can't get enough of the car I sold my 2008 M3 and 1994 Supra and thought 1 car might be better than two. Less headaches etc..

I have a straight pipe from the turbos to a custom X-pipe. Two different exhaust configurations came with the Porsche. The X-pipe sounds amazing and I love it!! Two little baby turbos in always in my ear is amazing! Video below

I took out the VR tune and installed a Cobb V3. I'm currently on Stage 2 ACN91 (I really hate AZ for this crappy gas). Speaking with Mitch to get the car protuned, hopefully tomorrow at BMR.

How lucky am I to have Mitch living 15 minutes away from my house??

I keep throwing the code C5604 on the Cobb every 3 cold starts or so. Any ideas??? I would really appreciate the help, it's driving me crazy and there is no description when I pull the code either than a CEL light on, not flashing but stays solid.

 

Evap system, check your gas cap

 

I checked it out and it looks fine to me. Should I just replace it?

 

that exhaust sounds realllllly good. Good luck with the code.

 

Thanks RONI1X!!

Boosted cars don't drone much which I absolutely love!

 

Ordered a new gas cap, should be here next Tuesday. I hope that helps take care of the code!

If any other codes pop up, is there a legitimate place you guys use to look them up?

 

Renntech for one, this site may have them too, do a search.

 

I've tried 5604 and didn't really come up with anything. Any of you guys know if the Cobb codes are same as durametric codes, dealership error codes etc..??

 

Same here , dunno wat it is , did u find it ? Just change out the gas cap and purge valve already , no cel

 

Why are you saying to change out the purge valve if you don't know what it is?

The gas cap will be here Tuesday. I sent Mitch some log files and he thinks my car is not happy with the last batch of gas I put in there.

 

Somy did you double check the code with any other device or app? Just to see if the CObb had it right.

 

My only option is to use my friend's Durametric but he lives pretty far so I haven't had the chance to do that yet.

He also recommended I replace the gas cap. I have no idea where the gas cap thing came from because I really can't find that code anywhere. I'm really hoping it's bad gas I put in there that is causing this.

 

just checking to see if you saw this post.

Yeah, I saw that thread. Thanks AZ996!

CEL hasn't come on in a few days now. I will still change the gas cap when it comes in Tuesday.

 

Can anyone help me with some datalogging? I'm wondering what numbers are within range for Timing, Camshaft angle, Lambda etc.. I found threads about Durametric datalogging. Someone usually posts their log and others reply saying it look good congrats, your IAT are too high, IAT look good, lamda looks like a giraffe but no chart or anything saying what is normal or within good range.

For example: The OEM ECU can pull up to -15 timing to save the car from detonation. Does that mean any timing pulled up to -15 is ok? Is any timing pulled a bad thing?
