Cobb AP Discussion Thread

Hey Travis, thanks for the response, I appreciate it! It's a 2006 MS 6 actually; I see the Stage 2 +SF 91 on the 2007+ speed 3 maps on your site, was that what you're referring to in your reply? I'm assuming I should only use ones you guys have listed for the 2006 MS, so it looks like I'm still out of luck there... are there any plans to release a map for the 2006 MS6 with the same configuration? I've got a DP w/ high-flow cat hooked to the stock catback, so hopefully there won't be any trouble with major boost creep (but I'll keep my eyes on the psi). If there's not a map like that on the horizon for '06 MS6, do you have any recommendations on what map/setup would be best to run? (super shredder suggested going back to stock intake and going stage2 91 w/o SF intake)

To BlenderCloud, thanks for the tips- I called up the Citgo you referred to and the guy said they weren't selling 100 octane anymore :( Not even selling gasoline of any kind any longer, for that matter, I think they're a repair shop now or something. A map of the KC area showing 93 octane stations would be awesome. If you hear anything more about stations carrying it, I'd totally appreciate a PM if you could spare the time! I'll check around with some more of my friends and see if they know any places.. and if I find any I'll be sure to let you know.

Sorry about that, I get my forums and cars confused. Yeah, if there is no SF intake map for your car then you might email call COBB or Surgeline Tuning about getting an E-map for your car so that you can use that intake. In the meantime going back to the stock intake would be a good idea until you can get a tune.

As far as running 100 octane. You don't need to upgrade your internals or run more boost/raise compression etc. to use these fuels. You DO need a tune. Dumping 100 octane in without a tune will make your car run poorly. However, on a tune we have seen as much as 50 extra hp/tq. Race fuel is cool stuff. Since it burns so slowly you can run lots of boost and timing and make a lot more power over regular pump fuel.

If you can, run Chevron. The techron additive is actually a pretty good burn inhibitor and is superior to other fuels of the same grade.

I think I answered everything... Just feel free to email me if you guys need to know anything else. If I can't answer it I will get the tuners and engineers on it.

No problem Travis, I appreciate you taking the time to reply :) Thanks for the info, I'll run with that for now and continue the hunt for 93 octane around KC!
 
Datalogging from new Cobb AP... how do the numbers look?

I hooked up my shiny new Cobb AP and did some datalogging after flashing the Stage 2 +SF 93 v101c. Below is the graph of a couple runs. From what little knowledge I've gleaned from the forums so far, the log looks like everything is OK, though is the boost supposed to spike that high (20-21.5) when the map says the target is 18.5 (+/- 1.5) peak, tapering (it does taper as expected)? And how do the AFRs look? I've read AFR should dip to around ~11-12 during WOT... which is right where I'm at; is that the general consensus?

Oh, and KR is at 0 for the 7 minutes I was driving, except with exactly six, single datapoint pings to 0.7 occurring (no higher), I couldn't hear or otherwise detect them other than in the log...is that acceptable and expected sometimes, or excessive and dangerous?

Any more interesting comments on these results or things I can log/compare/look at?

You need to look at your boost targets. I've seen spikes of 20psi for split seconds but return to my target with a Stage 2 map. Temp and humidity will play some factor in that as well.

I'm just happy to hear my old Cobb AP is being put to good use! Glad everything went well.
 
Great- thanks for the reassurance on the 20psi initial spikes guys :) All the other data seemed to indicate there were no other troubles... AFR on target, KR 0 except for a rare 0.3 or 0.7 split-second point. And Atryu thanks again for the AP, definitely using it and having some fun looking at the logs.

The graph I posted was logged about 10 miles into flashing; I logged again last night after another 40 miles or so of driving and boost spikes stayed <=20 over 25 minutes of driving and tapered to ~18 as expected. I will post a csv sometime later for kicks (left the AP at home, b/c I really need to get some work done today.. grr)

Going to buy an ETS TMIC now to see what that will add (and of course reflash with a new map that includes TMIC). Must... exhaust... bank account
 
Yet another COBB AP question.....

Hi there gang. Considering getting this AP. My car (2006 MS6) has the following mods:

Corksport tip/sri
CPE catted DP
Magnaflow catback exhaust
Turbo XS hybrid BOV

Available gas to me in Canada is 92 octane...(shell)

Are there any maps that are suited to these mods, or would I have to get it professionally tuned? The only reason I ask is that if I need a pro-tune, I would have to go to the states as there is no shop in my province with an all-wheel drive dyno, and this would not make it worth it for me.

Thanks for your help guys.
 
im holding 18-18.5 psi on Cobb AP stage 2..it says i should be hitting 19.5 psi in the discription of the map...im kinda gald im not lol..i have no leaks at all... but u guys that r holding 13psi..thats alittle low even if ur stock. u gotta have a boost leak somewhere. theres a thread somewhere to show u how to make a pressure tester from HD (home depot) and hook it to your stock inlet pipe..do that and see where ur leak is..fix it... its most likely ur stock BPV .. u should be around 14.5-16psi normally if its stock..

If you're looking at a possible boost leak, first place I'd check is your inlet pipe connection to the turbo. It's a known issue that they're not always on tight and easy to slip off. Hell, when I installed my Cobb TIP, I didn't even use a screwdriver and it fell off the turbo.
 
I'm attaching my datalog in hopes that some folks will be able to comment on the results.

I'm looking at a set of plugs that are one step colder to help with the KR. Let me know what you guys think.

(It's a log of about a 15-20 minute trip 'around the block'.)

Thanks,
Blendercloud
