Can anybody help me with a fuse plug pull?

[TDevilsG]

Hello,

I just got my 2ss and have heard many stories of people thinking it necessary to pull the 5 and 20 fuses on the SS. As i am just starting to get a little more car savy, is there anybody in the jersey area who might be able to help me with this? Thank you!!

Pull fuse 5 and 20 let car sit over night with fuses out. Reinstall in them in the morning. Just make sure you run 2 tanks of premium 93 octane before doing the fuse pull. If you need more info pm me. thanks

Ok, so what is this suppose to do?? I have heard about this a couple of times and would like to know more about it.

For a six cylinder, I don't think the fuse pull will do much. The fuses (5&20) give power to the long term and short term fuel trims for the V8 this causes the computer to go into the higher octane table and ignore the other trims (which are no longer stored due to power loss). If the car has ever had less than premium gas in it the info stored will be deleted. This causes the computer to deliver factory tuning back which should make the car faster.

*How to: Gain Horsepower By Pulling the Fuses In A Late Model Camaro
Gaining Horsepower By Pulling the Fuses In A Late Model Camaro

If you are new to owning a 2010 or 2011 Camaro equipped with the L99 or LS3 V8 engine, then you may not be aware of a simple trick that could unleash a few extra horsepower.

There are two specific spark timing tables housed in the memory of the vehicle’s Electronic Control Module (ECM). One is used for cars running high octane fuel and the other for when the vehicle is using low octane fuels. Whenever you drive the vehicle, the ECM is constantly making decisions based on the data it receives from all of the sensors in the engine and exhaust. Over time, the ECM will set your Long Term Fuel Trim (LTFT) to the low octane tables.

The problem: It seems that if someone puts a low octane fuel into the tank, the vehicle can’t recover from the low octane table. Once in the low octane table the car will continue to use that information even if you are now using a higher octane fuel. Of course the side effect of this is sluggish performance, and we don’t really need to explain the benefits of running a higher octane fuel in a performance application. If you just purchased your Camaro you wouldn’t be incorrect in thinking that it isn’t uncommon that at some point the car was filled with a less potent gasoline, especially if it came from a used car dealership or from an owner who was uninformed of this problem and wanted to save a few bucks at the pump. The LTFT’s are, unfortunately, a part of the car’s non-volatile memory. That means the information is stored there, and doesn’t reset when the vehicle is turned off.

However, there is a way around this problem. Although the spark tables are part of the non-volatile memory and cannot be removed, they can be reset. A simple solution is to remove a couple of fuses from the fuse block in the engine compartment. Pulling the fuses will allow your Camaro’s ECM to reset itself to the high octane table. If you are running high octane fuel then it remain in the high table until the ECM again detects a low octane fuel.

The process is quite simple;

First, make sure the car is empty of the low octane fuel. Run the tank down low and refuel with high octane. You might consider running a tank or two through before attempting the fuse pull. Once you have better gasoline in the system, locate the two fuses shown in the diagram below. They are in the fuse box located on the passenger side of the vehicle’s engine bay. The fuses are in position #5 and #20. Remove each of these 15 amp fuses and allow the car to sit for a period of at least a few hours. There is a small, grey fuse pulling tool located on the fuse panel (In the diagram below it would be in the lower right corner area). That should make the pulling of the fuses easier. If possible, remove the fuses and allow the car to sit overnight. Once they have been out for several hours, replace the fuses. When started, the car will attempt to use the high octane fuel trims first, and if you keep high octane fuel in the car it should remain on the higher table permanently. Of course, lowered octane fuel in the tank means repeating the process.

Thanks BlackCamaro and 2011SS! I am going to try this out after I run two full tanks of premium and see if I notice a difference! It has been SO hot out the past couple of days so I haven't had a chance to really push the car, but I have noticed that it is running a little sluggish/hesitating when stomping on the acceleration. The car also only has about 200 miles on it since purchase so I think that doing this fuse pull & hitting the 2000 mile mark or so (after the car is a little broken in) will allow me to really feel the full power of the car.
