***Updated Fuse Pull info, confirmed***

Thanks PQ, I think you've covered my questions thoroughly and clarified a few other things.... thank you for your patience....

NEW JANNETTY TEST
letts have a LS3 and L99 go to Jannaetty, dyno, fill tanks with 87 octane, at least three tanks, re-dyno, pull fuses for one hour, retest, fill with 93 octane for three tanks, redyno, pull fuses for one hour and dyno again.

OR pull fuse, or not and live with what you have, don't trust anything you hear on the internet, just live with a possible underperforming car you spent close to $40k for and be happy, or buy the V6 which doesn't have a fuse pull problem or for the L99's get it to run in 4 cyl. ALL the time.............THESE ARE PERFORMANCE CARS..........any way to get better performance for one hours time and NO expense makes sense.

Sorry.

Guys, a few things here.

It's just my opinion but I don't consider anything BROKEN here. Maybe it could be BETTER, but it's not BROKEN. So there's nothing to FIX. Is Bonnies Lexus BROKEN because it doesn't have seat position memory? No, it just doesn't have that feature. Is it sub-par to many other Lexus cars? In that regard, yes it is. So at the very most, the fuel sensing method of our Camaro is sub-par to some other models and makes. So what? Use high octane gas and forget it. If you have to use low, at least you know how to reset it.

Also, it's not a SUPER DUPER MEGA MONSTER difference in sound and 'feel'. It is subtle and can be overlooked. In my original fuse pull thread I explained the whole thing. It can be easily overlooked and I esaily could have if I wasn't so in tune with my car. I was paying VERY close attention to my car in the few months leading up to the fuse pull. And it was STILL a subtle difference. EVEN though I 'noticed' a difference it could have been EASILY a 'wishful thinking' thing. So I immediately went out to time it. Since I had over 150 timed runs to compare to, it was then AND ONLY THEN that I was able to say for 100% certain that this thing made a difference.

To me, it's a huge difference because I look at the time, and not the sound and feel. .1 in a quarter mile is a big difference on the track, but you don't 'feel' it much at all.

There is only two ways to verify this.

Time your car before and after.
Dyno your car before and after.

I did both. I have the before dyno where my air/fuel ratio was so lean it wouldn't register once ANY throttle was applied, but I don't have my second dyno sheet. So I don't mention it much.

BUT, I have my times. And if you don't like my times, just listen to the tires before and after.

NO problem. They are all legit questions.

I'd love to have this proved in a controled test. I don't need it to be, but I'd juswt like to see the HP and TQ differences. I know GMRULZ showed 8 HP with his, but .8 average seconds faster seems maybe there's more TQ advantage.

If you follow Jannetty and his posts, L99's should have 325 to 330 HP, mine was 305 HP,
felt like I got it back after fuse pull, actually on low octane table was 305/300, tuned on low octane table, 327/ 345, still did not feel good, fuse pull and WOW, still too busy to go back to dyno but have been very happy (and I have one of those untested vararam CAI too).

Humm typo, L99's should have 325 to 330 to the RWHP.

Um, I disagree with PQ on this broken thing. Yeah, I see this as an issue GM needs to fix. I should not have to pull my fuses to get the car to run the way it should. There are numerous ways to get low octane fuel by accident. Don't feel like pulling fuses every 500 miles to make sure I am getting the SS I paid for.

[MikeZ28]

I think this is a defect, not just a missing feature. As far as I know, many other GM cars don't have any problems adapting to different octane grades, including dropping down to the low octane table and going back to the high octane table when gas quality allows. I've never heard of the 4th gen Camaros, or the Corvette, or the late model GTO getting "stuck" in the low octane table.

[GTAHVIT]

I see both sides.

There are a lot of foreign cars that won't adjust down... meaning if you run low octane they stop running all together...

But certainly GM has proven to be able to produce an ECM that can learn in both directions, high to low and low to high...

I have mixed emotions on it.

[BackinBlackSS/RS]

Well, how many people really know about this? Not many. If the car goes into low octane table and stays there, there is less stress on the engine/drivetrain. This in turn decrease warranty claims. Just speculating. What do you think?

I would have to re-read but I believe that the manual says the car adjusts to the octane used, if this is the case I say it's a defect. The cars that do not adjust down have the fuel designation "premium fuel only" so it is not a defect that they do not adjust down as the manufacturer says it will not run properly on the lower gas. These car have the fuel designation "premium fuel recommended" the manufacturer says it will run properly on both; to me this means it should adjust so in my opinion it is a defect.

Meh......... maybe I'm just looking at it on a possitive note.

Yes, I would prefer to ALWAYS know that I"m where I need to be. But I am just glad I got the damn thing where it's supposed to be.

Post what the manual says. I'm cuious. I'd read it right now but I'm leaving to go get my headers.....................er............I mean, go to Jacksonville to watch Bonnie do her contest.

Good luck with the headers, um I mean contest.
