Pull fuse 5 and 20 fact or fiction? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

hansenp · 12-04-2009, 04:18 PM

Ok read alot about this on different threads but is there proof it works? I have LS3 installed a CAI yesterday so do I need to pull the fuses ? If so what order , how long . Or is there no real proof it works?

And yes it REALLY works.

Fact or Finction...toughy... ok, it is a FacTion.

CamaroFemme · 12-04-2009, 07:28 PM

It works IF you had lower than 91 gas in your tank. The computer isn't rechecking the gas once it falls to the lower octane table; pulling those fuses after you put in a good tank of gas makes it re-check.

I know it works because I've seen it.

Infern0 · 12-04-2009, 09:00 PM

Well, technically pulling the fuses is FACT regardless of what gas you use. If you pull the fuse it WILL reset certain volatile information previously stored in the system determining which fuel "mapping" you were on (either low or high). Whether or not you gain anything from doing it will depend on what was previously stored.

Meaning: If you used 91+ octane and you were already at the high octane "mapping", replace the fuse, then you will still be at the high octane mapping and you wont notice any gains. If you were previously stuck at the low octane like many of the L99s, when you replace the fuse with higher octane fuel, then you will now be at the higher octane.

That simple, not really anything up for debate. It's not meant for simply adding HP every time you pull the fuses.

perfect then cause When I first got the ss camaro I used 89 till one day it started pinging so I asked on this site what octane to use and boy did people let me have it when I told them I was using 89 but from that day on I used 91 never pulled fuses till today after adding roto-fab CAI and flowmasters bolt on system.So lets see what happens

Ok...you've got us curious...please post your results. Most of us that have had success with the 5-20 fuse pull are L99 owners. Let us know what it does (if anything) to your LS3.

Cheers,

I have an L99-2SS/RS that I purchased in Mid-September. It really helped my car enormously. Not knowing about the fuse pull beforehand, I asked the dealer what octane gas was used to fill my car up at purchase. It was 87-89 (can't remember) but definitely not premium.

I came across Camaro5 and just like everyone else was amazed at what I was reading about this fuse pull. I use pretty much the same gas station with all of our cars and fortunately their premium is a 93 octane and that is what I put in the Camaro the very first time I put gas in it and every time since.

With that being said, what the heck, took the chance 2 weeks ago with 2100 miles on it, did the fuse pull one evening, the next evening reinstalled the fuses and what a difference it made. It felt like (with the dealers tank of gas maybe a 200 hp engine) With the Premium I used from the get go along with the fuse pull ( I know its only rated 400hp) but it honestly felt like someone had put a nitro top fuel engine in the car. It was that huge of a difference.

I am now happy with mine very much. I am also very surprised at this probably more so than the "feel of the engine".......My avg mpg went up by 1.7 mpg city and by 2.1 avg on highway. Hard to believe but I guess with the car's brain being jossled from the fuse pull and the right octane gas the car can TRULY reach it's intended potential.

I also did the same fuse pull on my sister-in-laws Camaro / L99-2SS/RS. She got the same results. Better engine feel and gains in mpg.............

Ok dang I guess I have to feed into this pull the fuse thing. Two days ago after I finshed my install of my CAI on my LS3 I wanted to of course see if there was a difference so I hit the road it not only felt slower but also slower to respond kind of slugish thus the question here about pulling the fuse. Even before I got an answer I felt like I had nothing to lose so I pulled them . When I put them back it was like my beast was back. Quick to respond at least, didnt really step on due to traffic but all I can say I felt a change from the day before for what ever reason so I vote for FACT even for the LS3 under certain conditions.

SJ LYNN · 12-05-2009, 12:08 PM

Hey hansenp,

The main thing here is at least you got your beast back. Even though traffic hindered you from actually testing it out, do you think your CAI was worth the investment?

Just curious.......since other than tinted windows and doing the 5/20 fuse pull my car is exactly as it was when purchased.

2Fast4U2010 · 12-05-2009, 12:22 PM

I have the 2SS, I had to pull the fuses because the dealer put low octane gas in the car. It ran like crap, low and behold it ran better and like a bat out of hell, NO problems since then. I will also be doing it when I intall my CAI soon.

In my opinion the CAI completes my needs short of installing headers . I feel you need complete air flow ,if u bring more air thru the CAI then you need an exhaust system to let it flow right thru with less restriction ( in my case the flowmaster stainless bolt on system) let me tell you this it does make a deep growl when you step on it and responds well . I got intake from roto-fab last week because they were having a holiday sale and every dollar count for me.

SJ LYNN · 12-05-2009, 01:41 PM

Sounds good. Keep us all posted as you make any further mods along the way. The path you have taken is the same as I wanted to do. Get some more air in and then enhance the exhaust to get the spent gases/air out.

Thanks again for your feedback !!!!

SS/RSLS3 · 07-28-2013, 04:11 PM

New to this. I apologize in advance if i insult someones knowledge... Fuse pull should be done and then put back in a few hours after both fuses have been pulled? I just purchased my Camaro LS3 and it has been filled with 89 octane since new. I started to put 93octane but I still here a slight knock at high RPM.
