I have read in some threads that for every 50-shot of nitrous, to be safe one should reduce timing by one degree.

1. What does this mean--what is a 'degree of timing'?

Currently my '05 v6 has no mods. I'd like to get CAI, U/D pulleys, rear gears, and some sort of performance tune that can give me 15-20 horses or so (all this for everyday driving...no nitrous). I have heard that a tune such as this ADVANCES timing.

I have also become interested in nitrous so I can blow the sox off ricers. Obviously, I only want to be able to use this only when I need it. So here's the problem...if I get a tune that advances timing so I can get more HP, this would create a very unsafe situation for my engine if I were to run nitrous, correct (say a 100-shot)?

2. How do I get the best of both worlds? I don't want to only have power when I'm using nitrous. That's why I want that performance tune for everyday driving.

I know the logical answer is to get two tunes...one which advances timing for when I am not using nitrous, and one that retards it for when I am. But that really takes away from on-the-fly or nearly on-the-fly capability. Remember, I want to just be able to turn on the nitrous and use it right when I need it. Ideally, I'd like to have that performance tune going and still be able to use the nitrous at random times...is that possible for a SAFE setup?

Any sugguestions would be greatly appreciated. Thanks.

 

If you are planning on running a 100 shot you will need a free flowing exhaust. Especially when your putting it on a V6. This is because thats a rather large shot to start out with on a V6. The free flowing exhaust will let the exhaust gasses out faster than your stock exhaust. This is important because a restricting exhaust will cause alot more detonation. The engine will run cooler and you will gain more power N/A. You need at least a midpipe and a cat back kit. You dont have to do all of these things but this could save you an engine one day.

You need to put different spark plugs in it. Copper core plugs are the best with nitrous use. They need to be one heat range colder. NGK makes nice ones and ZEX just came out with some.

So skip the CAI and U/D pulleys and put a good exhaust on it. It also makes more power while on the spray.

You shouldnt put a standard chip or any standard performance tune on your car when you have nitrous. It does advance the timing and it will blow your engine if you spray with it. You want a custom chip that sharpens the fuel trims but keeps the timing stock. With a 100 shot on that car I would really retard the timing a bit.

Also make sure you use 92 octane or higher because the cheap stuff will cause detonation on a stock tune.

Change the fuel filter and run a can of injector cleaner through it before you install the kit.

I have all of these things done to my car except for a custom tune and its been running great for the last 1 1/2 years ive been spraying it.

 

Use the NGK TR6 plug part number 4177. this is one heat rang colder and is copper so it will melt before the piston does in a lean situation.

nd like he said you cant and dont want to run a chip with advanced timing in it while spraying, and you want ot run the highest octane gas you can get before you spray the car.

 

thanks for the help...

I am still curious, however...

Like I said, I want to have power during every-day driving, too. So could I get two tunes---one that advances timing and incorporates any mods (not nitrous)

and one that retards timing and incorporates nitrous?

i also don't really want to spend the money on dual exhaust, because for everyday stuff i hear I will lose low-end torque on a v6. Is it nearly a must for nitrous use?

 

no you can spray a bone stock car if you want to. my freinds x5 has a 75 wet shot on it thats it.

Burt yes you can get a tuner or a chip with up to 4 tunes on them so one can be nitrous and the others can be whatever you want for daily performance.

 

Yea you can spray a stock car but I would keep it on a low shot maybe 75. definately not 100.

Yes you can have 2 tunes but you said you didnt want to pay for a flip chip didnt you?

Nitrous isnt something you should really mess with if you cant do it right. Im not trying to be an *** im just giving you the facts. I say just put some gears, a chip, and an exhaust on it.

 

a good exhaust is not going to give you a noticeable drop in torque anywhere in the powerband.

The HP and TQ gains across the top of the rev range is what you will feel.

If you plan on making any decent power with your car you will need an exhaust. It just wont happen with the stock exhaust. And youll get better gas mileage.

 

What's a flip chip? I don't think I mentioned anything about one.

As for the exhaust...it's hard for me to tell what the truth of the matter is. Everyone in this forum knows a lot more about cars than I, but there is much debate about it on this subject. I also called a mustang specialist mechanic, and he (who would benefit from my sale) said that I would lose low-end torque...and that exhaust won't do anything for me power-wise unless I was traveling "130 mph."

Dubious of that, I called the Ford dealership where I purchased the 05 v6, and they told me it really wouldn't do anything either way power-wise...that dual exhaust just looks and sounds pretty.

Now, I didn't ask either of these guys what I should do if I got nitrous. But it still seems that some folks say that duals give power and others say it takes away (for a non-nitrous car at least).

I have no idea what to think. And I certainly don't want to spend $$$ if it won't help me/will hurt me.

 

A "Flip Chip" is a chip that contains 2, 3, or even 4 tunes on it. It has a switch that you use to change tunes on the fly. Im pretty sure you said you didnt want one but i dont remember now.

Well the people are telling you the right answer when your talking about just a simple cat back system. That means from the Y pipe back to the tailpipes. But I meant you need a midpipe too. Thats where you gain all the power. It eliminates one or even both sets of catalytic converters. Your car may even have six I dont know. But It lets the engine breath alot better. On V8s we gain maybe 10-15rwhp with it maybe more. Definately more with nitrous maybe like 20-25. The engine will be less prone to detonation too.

You dont have to get the exhaust but youll probably wanna be careful with the shot you spray on it. Just use the best gas you can get unless the prices go sky high again then you just wont be able to spray it.

 

I must have gotten confused about the chip. That actually sounds like a good idea! Exactly how 'on the fly' is it though? I remember reading in some thread that you must turn off your car and back on for it to recognize the other tune. Or can I simply change to another tune whilst driving down the road?

As for the exhuast, I see what you mean by eliminating the cats.

Thanks again.

 

By "on the fly" it means you can change tunes while driving down the road. BUT, if the tunes are too different, you may not be able to do this.

There is an issue with the traction control. Whne I change to and from my nitrous tune, my car stalls BECAUSE of having the traction control come on and off.

It is no big deal, because I just restart the car. With a tuner, you have to get out of the car, plug stuff in and wait a few minutes.

 

So if I just wanted two tunes:

1. Advance the timing and use 93 octane (for when not using nitrous)

2. Use the stock timing (for nitrous)

would I have to restart (lets say I had nothing else incorporated into those tunes)?

Also, how reliable is the chip at actually switching the tune? What if I flipped it but it did not register, and then I used nitrous when I had the advanced timing tune turned on.

Also, someone told me that I can't get a chip for the 2005 models. I have to use the SCT XCal 2. Is that true?

 

1 - Don't know about your 2005 chip availablity question.

2 - The switches are very reliable, but anything can fail.

3 - If you are going with the venom system and you want your timing stock, then I would not bother with asecond tune, just switch back to stock when spraying.

However, if you get gears later, then your nitrous tune might be nothing different except for just accounting for the gears.
