you must have heatsoaked pretty bad to yield so low numbers.

I emailed Cobb asking if the ap would save he Ppk BMW software flash/kit, and hey said it won't back it up as a factory rom.

So will I lose the ppk or good?

raceyBMW · 09-20-2012, 11:03 PM

I have a question for you Cobb gurus. I will be heading to the track this weekend (a track with turns, not a drag strip), and am considering going to stage 1 or stage 1+ to help turn down the boost and keep temperatures down...I have a problem with coolant temps usually at the track. I usually run Stage 2+FMIC drive.

I am FBO, and I know it will throw a code for the missing cats, but is this just simply a code that it knows they are missing, or will it make the car run differently. Is this ok to do with the mods I have?

Carl Morris · 09-21-2012, 12:06 AM

I don't know about missing cat codes, but I wouldn't recommend Stage1+ if you're trying to keep temps down. It uses a lot of boost.

type rrr · 09-21-2012, 12:21 AM

^^ x2--- i would go with stg 2 sport or drive

raceyBMW · 09-21-2012, 12:31 AM

Thanks guys! Maybe stage 2 drive it is.

Bash · 09-21-2012, 09:11 AM

S2 drive is slow, s2 sport is a bit better for the track.

raceyBMW · 09-21-2012, 10:20 AM

Slow means less boost, which means less heat, and less a chance of me going into limp mode. I am ok with a bit slower in the straights at the track as long as I don't limp....its a real fun ruiner when it limps and I have to pull off to let cool for a couple.

After installing the exhaust and doing a few test pulls, it seems like the power is there but it continues to cut in an out. Almost as if it is getting shorted of fuel when I step on it. Best I can describe it would be a jittery acceleration. However, a couple of times running up hill I really felt the new power but it isn't consistent.

Please any suggestions to this problem would be greatly appreciated.

I have the same problem. Whenever I hit the pedal very quickly I have a jittery acceleration the first 1-2 seconds. Afterwards, the car is running great. What can I do to solve that problem? Thanks

Since I have RB turbos: Is it possible that my ECU overshoots load target (because of my stiffer wastegates) and as a result the throttle closes? If yes, what can I do? ProTune?

Are you running the RB map? if not ask COBB for it.

If that doesn't fix your problem, contact PTF... They'll fix your issues, and you'll end up with more power

335bmwjohn · 09-21-2012, 12:43 PM

This is the route I am going!

I alread asked COBB but I do not get a RB map since every set is different.

Cobb Accessport is a wonderful addition to my mods. i love it...my 335 is a beast now. Thanks ti Gilbert from **********s..he is the BEST.

Will buy from him and **********s again.

Blend and oct?

I would fill up with 9 gal. E85 and 7 gal. 93oct (contains 5% ethanol here in Germany). In total it should be approx. 100oct and 50% ethanol (E50). Or is that blend too much for fueling?

On a healthy fuel system 50% isn't a problem. If you have a weak link(usually a LPFP) then you may not be able to run that high of a mix. When properly tuned for it a 50% mix can yield some AMAZING gains, just look at Vneblob's PTF thread http://www.e90post.com/forums/showthread.php?t=746740

Are you planning on doing a Dyno Run?

enrita · 09-21-2012, 03:59 PM

Fuel system has nothing to do with blend. I am tuning now on E50. Is power output that dictates if you menage or not. Also you cant think octane with e85 since on DI the knock limit is way higher because of the cooling effect of the direct injected charge.

Enrita, would this 50/50 blend yield more power than running strait 104 octane race gas?

depends on the tuning. E85 has cooling effects as well. with E50 i can run very aggressive timings like 3K - 13.5 to 15.3 at redline with almost no corrections at all. engine response is amazing with this high timings.
The beauty of e85 is that is cheap and available at every station (in sweden) . my mpg though is much worse. last tank i did only 280 miles .

EJ_3 · 09-23-2012, 09:33 PM

In preparation for moving out west where there is no 93 octane, which option do you think will be the best option for performance and fuel consumption?

1. Run the new e85 map with 91 octane mixed with e85.
2. Continue running Stg 2+ aggressive with 91/e85 mix.
3. Get a protune 91/e85 map.
4. Run e85 map with 91 octane and meth
5. Get a protune map for 91 octane and meth.

Thanks in advance.
