Nitrous Tune

Post by squirrelcv » Thu Oct 25, 2007 11:14 pm

I just bought a Nitrous kit for my GT. I'll retune for this change, but I'd like to know what that tune does.

Will I still be able to drive my car normally? Will it simply richen the A/F ratio?

I'm unsure.

I know I won't use the Nitrous much.

Depends on what you choose for the wet or dry settings. What kit do you have? The SF will automatically retard the timing for the amount of nitrous you are using based on your answering of the questions.

I bought a Nitrous Express Wet Plate system. I rarely intend to use it, and NEVER around town. I couldn't pass up the offer (25% original price w/ additional equipment).

I'll have a window switch for it, but again, I won't have the kit on much. Will my timing be retarded all the time, or just when I am within the window? I'm not sure how SF compensates for that. I mean, with a SC or Turbo, you always have it on. With nitrous being totally at the driver's discretion, I'm worried that I'm stuck with one timing that isn't variable. :(

I don't want to ruin my engine.

This would be a queston for Patrick and the guys. I don't know where it pulls the timing from on every tune in the SF. If I were making a tune with delta, I would only pull the timing in the WOT load ranges. There maybe another option for you though.... does your car have an octane plug? A custom tune could be setup to pull timing when the octane connector is out for your nitrous which is a quick solution (if your car has it). Consult with a ford dealer unless someone already knows if and where the octane plug is on your car...

Oooooohhh I don't think there is.

Basically, my main question is this:

If I tune my car for Nitrous, will the ignition always be retarded? Or, will it interface with the window switch or something?

I'm getting the kit on Friday and I don't want to blow up my engine when I'm not using it.

I'd like to be able to harness the power when I need it, but not worry about leaning out and blowing a rod/piston.

Why don't you just upload the NA tune and drive with that, when you think you want to use the nitrous upload that tune, I mean it only takes a minute or two what's the big deal?

Retarded timing (less timing for the nitrous tune) actually makes less power and is easier on the engine. If you are running your nitrous tune without the nitrous you will make a little bit less power and you won't be risking anything..... I guess i was confused by your statement.

Right now, my timing is advanced for the 93 octane fuel. If I simply spray in a SMALL shot, it'll run ok, right?

I'm sure as hell not putting a 150 shot on a PI intake.

If you put in some octane boost or mix some race gas in the tank with your premium tune and add nitrous. I would pull 2 degrees for every 50 horsepower of nitrous you are using.
