COBB Selftuned 335is Traps 120+ in 1/4 Mile

First I would like to say, thanks Wedgeperformance for hooking me up it was truly appreciated

This was just a scrimage to go out and see what the car was capable of doing in a 1/4 mile run. I was not aiming for ET here, but aiming for speed traps instead.

There was just too much torque for street tires on this tune, and I found myself feathering the car half way through 3rd gear. The backend would not stop moving around so I could not give it 100% throttle more till it settled in 4th. Indeed I will make adjustments for this next time.

I screwed up big time when I added too much race gas to compensate for the trouble my LPFP was having with anything above E30 at this power level (FUEL-IT STEVE HELP ! . In the end I had like E20 after adding the race gas . However I noticed using race gas my IAT got high quick as apposed to using E50-E60 my IAT never saw anything above 150 when pegging the needle. When I used race gas my IAT hit 160f at the end of the track wtf. So that was just a waste, I should of just maxed out my trims for the hell of it so my timing wouldnt have been pulled IMO. I was targeting 13 timing in the top

Yet again the South Florida weather and humidity is absolutely no joke, its like always being in a sauna

Keep in mind my car is "not cattles" I have the cP-e downpipes with HighFlow 200 cell catts, and OEM mid catts, I weigh 250 lbs and I had a half a tank of gas, no meth, full street trim, and no weight reduction. There will be another 335is that will be running the same tune with cattless downpipes, upgraded LPFP, and the drive weighs significanly less than myself

Full Mod List of my car:
  • COBB ATR Selftune (BQ Tuning) for E50-E60
  • aFe Stage 2 Elite CAI (Custom vacuum sealed)
  • cP-e downpipes with 200 cell HighFlow Catts
  • Dinan FMIC
  • Dinan Free Flow Axle Back Exhaust

After upgrading my LPFP some E50-E60 and cooler weather Im looking for 122 unless the other 335is that has the same tune beats me to it and he's got DRs also

Nice times and ET man.

And personally, i'd rather deal with high IATs 10/10 times over a potential lean out due to the DME not being able to rescue things with trim. So don't think you were at all wrong to add in race gas.

Awesome job! Making me itch to get back to a track. Great trap and 12.1 on only a 2.1 60' Do they still require roll cage at 11.99 or lower there?

I just wanted to chime in and give a shout out to Wedge Performance. I am also running a Cobb AP with custom e85 flash by Wedge and my car is running great and pulling like a beast. Made the jump from the jb4 ship and couldn't be happier. Thanks Ken and a thanks to Bob in Fon du Lac WI for getting me hooked up with Wedge.

It's DCT, so it's a 7 speed. The first 5 gears are pretty short. Where does it say he hit 5th gear though?

-Edit, never mind, he does hit 5th gear in his old you tube videos, yea, like I said, first 5 gears are short on DCT.

Yeah.. That's for sure..
Even with good driving, the 6mt usually results in a 0.1-0.15s loss per shift so its already down close to 0.5s..

That's some monster torque. Great numbers on that heart breaker.

Wow, all this positive Cobb talk is making me think it might be time to jump ship also. I used Cobb on my Subie's with great success but am using the JB4 on this platform. I'm happy with it but the community seems to be developing tuning thoughts with Cobb quickly at this point. Great results@!

ROM version is ILA0S_IS

Its the second to last ROM update before INA0S_IS

Everyone using the COBB OTS maps will have post shift delays on the DCT 335is which timing recover will look like complete shnit

The reason for this is the OTS maps is based off of the older N54 cars that do not have DCT.

I am offering a FREE BQ revision of their OTS maps to fix the post shift delays and fix "most" of the timing recovery horrid to where it feels as it should ie kick azz . All you have to do is PM me the following:

ROM version of the car
OTS MAP Complete name
email address

If you want to go anything further than this you will have to contact @Wedgeperformance

Please Note: Wedgeperformance NO LONGER SUPPORTS advance timing BEYOND what the COBB OTS maps have modelled after.
