Hey guys,

So last night, I decided to take the car out and do some spirited driving. After driving around for a little while, I went to a back road and did some WOT pulls. As you can see in the video, I went from 1st to 2nd to 3rd, but then in 3rd as I was approaching redline (between 6-7K), all of a sudden I felt/heard a jerk/bump and the RPMs stuttered. I thought I may have hit a patch of ice or snow so I tried it again. I was able to replicate this 3 times in a row. Third time I recorded it. I immediately went home, flashed the car back to stock and call a couple of people about it.

I then picked up my brother-in-law who has a 9 and we went out to see if I could duplicate it and maybe diagnose it. Well, long story short, I could not replicate it anymore. I then flashed the car back to stage 1/93 octane, and still could not replicate it. I ran the Cobb AP to monitor performance while we tried to replicate it, and my peak boost was 25PSI, and I had no trouble codes.

My buddy then called and had me look at my fuse box and we confirmed that I don't have the updated fuel relay. We chalked it up as this being it, and I'm going to stop by AMS tomorrow and pick it up, but I wanted to see what other people on here had to say about it? Any idea what it could be? I already zip-tied that little hose under the engine cover (near the dipstick) that is known to pop off, and I've only launched the car twice since I got it.

Really? Are they common at these temperatures?

Change the relays and go to the dealership.

I get the relay suggestion, but why the dealership?

I figure she still be under warranty. Let them pay for the relays

Fuel cut because it's cold outside, you're probably over-boosting which is very common in temps that low. Give the LWG version of that map a try and my guess is that solves your issue.

Overboosting? Do you think I did any damage?

Also, I don't believe I saw an LWG version since this is still Beta map

True...but I rather not go through the whole hassle of making an appt. (i can only go on weekends) and waiting for them to check it, the replace it. I already bought the relay from AMS for $15.

No damage, that's why fuel cut is programmed the way it is; basically acts as a limit. Talk to BakaUnchi, he should be able to set you up with a cold weather LWG map.

Thanks!

try switching to the 91 octane map but keeping 93 in the tank

With the cold weather we have been having in illinois lately, the fuel is cutting. Also is your boost spiking? Get a relay and you should be good.

guswaym

the relay isnt a magic fuel cut disabler i have the relays and when it gets cold i spike and cut and im pro tuned you need to have a map with lower boost ie lwg map suggested uptop to compensate in the temp changes..

Hey guys,

Spoke to Cobb Tuning last week, and completely forgot to update the thread. They saw the video and said I was indeed overboosting due to the lower temps. They recommended that I replace the fuel relay and switch to LWG software in lower temps..

However, where can I find this LWG software? I thought it would be on my AP but I don't see it. I reached out to them on FB Friday night but they haven't replied.

I know I have an '11 so it's still in Beta, but does that mean they don't have LWG maps yet?
