Select-able Cam Timing part of the performance pack?

You will need to remove the catalytic converters if you don't want them to melt and clog the exhaust after a few thousand miles.

So the Boss with Track Key has no catalytic converters? Or what is the difference there?
Thanks.

The Boss's track key is so mild it doesn't affect the cats. When you get into a real cam tune it dumps a lot of unburned fuel out the exhaust so it is very dangerous to the life of the cats.

Ok, thanks. But the Boss sounds pretty good idling with Track Key anyway. So just for the sound, a mild tune would be sufficient - good to know

And the Boss Track Key makes no appreciable difference in HP or torque numbers. Whatever it's doing for me on the road course is tough to determine without back-to-back comparisons. I know it's different from driving with my plain key, but it's difficult to quantify. I agree that there should be a switch to turn it on and off.
The other thing this needs is a far more sophisticated traction control system. Dare I say "competition mode" or will the Corvette haters get riled? Because it does work very very well there for them.

:clap2:I am in the same corner as the OP. I want a switch to flip to change the cam phasing.

I fully agree with this. There's so much potential for computerized stability control, but it's wasted. Most (all I've personally driven) could be better described as a vehicle performance limiter, when it could/should be something that enhances the overall capability of the car (improves turn-in and allows the driver to better correct oversteer without losing as much speed, etc). It's no wonder people just switch things like that off when having fun at the track.

Be careful what you wish for. Be very careful.

Why? So when the switch is off your engine makes less power than stock?

Probably because you can have better fuel economy while cruising and a little bit extra power and a nice sounding idle with the flip of a switch when you want that. I definitely would like that.

Ti-VCT already allows that all the time without the need for flipping switches. The system is constantly variable.

Must be the choppy-sounding idle they're looking for that'll impress all those people who don't know what it really means. Those who do know will just shake their heads a little.

I welcome you to teach me in this Ti-VCT a little, but I would think the variability of the system is dependent on various parameters/driver inputs, that are stored in the software. So you could get two different "profiles" for the timing variability by flipping a switch.
Isn't that a part of what the track key for the Boss does? (It likely changes more than just timing...)

It is not about impressing people or not knowing what it does. For some people it is not just about performance, no matter what a car looks or sounds like, but about sound (and look), too.
For example, to me, the sound is pretty high on the list of the most important things in a car.
And am I right in thinking you will shake your head over a Boss with activated Track Key?


No hard feelings.

There is plenty of research you can do on your own regarding Ti-VCT.

The bottom line, variable cam timing allows maximum performance, fuel efficiency, and driveability, all at the same time. No flipping switches are necessary.

Now that we have that all discussed out I have 2 questions: What is the consensus of what the driving mode switches will do in regards to engine performance, if anything? If Ford has the engine set for maximum performance, fuel efficiency and drivability how do ECM tunes improve on this?
No arguments, just seeking information.

Driving modes change pre-selected traction control and steering settings, plus change throttle response. Engine performance is set to the maximum Ford is willing to offer with a warranty. Aftermarket tuners are not as restricted as Ford OEM so they are allowed to extract a bit more performance from changing the tune.
