Or somebody with a shop manual could post them. I know at least a few dozen people who have them.

SHOP MANUAL !? Do you know where I can buy one for my 2012 SS? I've look around and can't seem to locate one.

Pretty sure there is info to get one in your car's owner's manual...

HAHAHAHA,

now you sound like me the day I yelled at a new guy in the shop who kept asking me all kinds of questions.....although I realize you were not yelling

Hard to believe in 89 pages of posting, not a SINGLE person has done this on the dyno. We got people with $10,000 just in parts in this thread...but no physical evidence this actually works......

Agreed. I'd have done it but started modding right after. Once modded it doesn't matter.

BUT, there is really nothing to prove any more.

The 5 and 20 fuses are not the ones that should work. The one in the trunk will.

There is no need for proof of the gain from resetting the ECU. My dyno was enough with the AFR dropping below 10 and the time gains and vids are plenty. It just wasn't the fuses I pulled. But the dealer reflash.

The gains are not a big 'butt dyno' difference anyway. I said that from the beginning. But that loss of low end torque kills the launch.

I am fascinated by this thread... The statistician in me says there are too many in the sample size that say the fuse pull works (at least one standard deviation) for it to be completely lore...

But at the same time from an engineering standpoint its impossible to have an effect with no voltage being held or passed through....

I just bought my 2010 SS M6 a couple of weeks ago ( 5K miles

) and i am figuring someone put low octane fuel in the car at some point... and I would hate to think I was running on the lower octane schedule...

So, I plan to check the voltage of the fuses immediately after shut down to test the "retained power" theory.

Will report back the results.

Try the #13 fuse in the trunk. I'd like to see that one tried as well. That's the one that is called for and the one that will reset the ECU.

Yes, that came out of a heavy equipment mechanic's fingers, I do understand electrical systems to some degree believe it or not.

And Bucci, thanks for jumping in and willing to help us figure this out.

Kinda like a junction?

So wait, pulling fuses 5 and 20 is now a placebo effect? WTH?

Unless someone can show how two non-powered fuses can reset the ECU then yes. It was a coincidence with mine. Thought is was the fuses but apparently was my dealers reflash.

So, I don't know what the hell happened with the rest.

I'm seeing some good numbers with just tunes. Maybe this has something to do with it. Just buy a hand tuner. Best bet in my opinion. The map gets reset with a tune anyway.....and they are good after parts are added.

Fireguy · 10-10-2012, 09:29 AM

Did it last night. This actually worked. What a difference.

2013Ashen2SSRS · 10-10-2012, 07:16 PM

OK so I have a dumb question and it may have already been answered...but I live in Wyoming and the highest octane I can get at the moment is 91 octane...is this considered a low octane to where it would effect the engine like 87 octane? Will my car be in limp mode with 91 octane? I have never used anything lower than 91 octane and I am pushing 3000 miles on the 2013. Just wondering if I should pull the fuses to see if it helps boost me any from where I'm already at or give different feel like so many are saying. Oh I am all stock, no mods!!

Not exactly sure what you mean, but in order for a circuit to work it has to have power and ground. I do know that if you are doing a continuity test (with the battery unhooked, which is the way it should be done) if you check continuity from the frame (ground) to a fuse that is normally (with the battery hooked up) positive, you will see continuity. Easiest way to explain it---a light bulb has power coming in on one side and ground on the other, the filament completes the circuit and lights up. If you turn the power off, the filament is still completing the circuit, so if you check continuity between ground and the light's switch, you will have continuity but with the resistance of the light bulb.

1. I do not know how or if this info plays a role in this whole thread.

2. If my rambling of what I know about electricity is boring or confusing anyone, I am sorry.

3. If you would like me to stop rambling, please say so.
