Is this possible? Need for Speed NOS button tune

Ok guys, hear me out

 

Here's what I want to do

 

Picture a day at the tracks, coming through the corners nicely on a low power tune for the track, keeping the rear in line and tackling the corners nicely. Then, out of a corner into a straight, foot down...

 

What's missing is a button that changes tunes to a higher kw tune so that when you hit the straight, you can press the 'nitrous' button, Turbo psi increases, injectors open up, etc and you get a solid pull along the straight. Switch back to the track tune and hit the corners again. Obviously would be nice on the street too if you want to swap easily between your daily power and a more powerful tune at will.

 

Sort of like playing a playstation game and hitting the nos button just when you need extra power

 

Is this possible? Can we do this?

 

I really need this in my life

anything like this is do-able as long as you're willing to spend the money on the parts and the ability to control it haha

it won't be cheap... you'll need all of the NOS kit hardware, plus the relevant tuning platform your tuner uses plus heaps of dyno time, plus the relevant hardware for NOS detection etc and the ability to switch tunes dynamically...

Sounds like you are saying you want a NOS style button, not actual NOS?

Doesn't the accelerator pedal already do this? You modulate it based on how much power you want in the situation.

If you wanted it more subdued at light throttle and all the hectics at higher throttle, your tuner can easily map it that way in the tune.

PCMTec can do boost by gear, so you could have it tuned for different boost targets depending what gear you are in. Can also have the tune switchable from the cruise buttons, but not quite suited to actually changing it during a lap, between corners, etc.

For an actual button or switch to immediately change the tune you'd probably need to look at going to a Haltech ECU.

Yeah you can do that easily.

 

Just use PCMTec to activate all the stuff with the cruise control button.

 

Pull for hecticness, release for normalness.

Nah. Just use PCMTec and the cruise control button as a scramble button.

You've gotta hold the cruise control to keep it changed though, otherwise there is another feature that can enable tune switching while it's running, but that is more of a thing to do and isn't what I'd be doing, to suit the first post.

Doing that can cause danger to manifold and then floor pan can fall out,, do it at your own risk!! 
 

but in all seriousness like the boys said pcmtec is good but if you want it on a dedicated button haltech or other quality ecu is the way to go....

haltech on the falcons is good but it ain't good enough for what they charge for it
