I'm talking about Joe Shmoe on the street here, who has never been to C5 before. I think this still needs to be addressed by GM. Putting a lower octane fuel in my car shouldn't hinder it until action is performed by me... it should reset after a few good tanks.

This is correct. IF they even realize they have a problem. A lot of people feel the power that's still there and believe they are good to go. I think a lot of people here had the 'slows' and didn't realize it.

As I said before, I could feel power, just not speed.

Yup.

I'm taking no chance! I just emailed my dealer to make sure they put 93 in my LS3 when they fill the tank.

It's also nice to know that it is as simple as just removing 2 fuses to reset the ECM if there is a problem. Hope GM sorts it out all the same.

Thx guys for the info. Scott, you just need to see if your tires are covered by warranty now!

My LS3 had a full tank of 87 in it from the dealer but I've been running 93 since then. I just pulled the fuses so we will see if it helps in 3 or 4 hours.
The car has been 8.72@85.03 mph in the 1/8 so if this helps it sholud be a bad mofo!

PULL THE FUSES, pulled for one hour, with rolling start, in D (so in second gear) with Traction control ON, churped 2 to 3 AND 3 to 4 shift, had to let off, need longer road for other gears, before fuse pull did get 2 to 3 churp. You can feel smoother idle and MPG seams to be going UP, will watch the MPG for a few tanks, this is at 2000 miles and before oil change, probably do that tonight. So my L99 did benefit.

How is pulling the ECM fuses actually doing anything?
Lets it discharge or something ?

This is great news and thanks to everyone on this forum who post helpful solutions to

problems. I didn't realize there were so many L99 owners other than myself who thought the car felt sluggish. I just thought that maybe my expectations for the car were higher than they should have been. Will go home tonight and pull #5 & #20. Thanks again!

I guess what I ment was.. from a technical point of view. I am very analytically minded so I like to know major details of stuff. (possibly why im in the IT business lol)
Pulling the fuse will actually discharge the ECM? Thus making it a blank and have to re-learn.. that sound correct? That's what I am to assume after reading everything.

Dude your one funny person. That post of you in your garage had me laughing all day at work the following day. Guys at work thought i was on drugs or something laughing all day

Mosher · 08-25-2009, 05:30 PM

Man... I think also Dealers should be warned to NOT put regular in the V8's period! Really good find.
