SCT doesn't want our money

Having a tune is less about seeing huge gains than it is ensuring your car car operate safely and effectively with aftermarket parts. A bunch of bolt-on's won't be 100% effective and can cause your a/f to run lean without a tune to correct it, leading to engine problems in the future.

Getting a tune is about maximizing the engine's performance in the state it is currently in.

Yep,especially with modern ECUs an intake and exhaust can alter fuel tables enough to actually hurt performance and/or MPGs.

All I want is to be able to fully turn off the electronic nannies and enjoy driving the car myself. The more I get used to my 2012, the more irritated I become with the stability control sucking the fun out of the corners. It jumps in anytime there is even a hit of rear biased yaw.

I dont need a tune to do that. I can toggle off traction control from the dash menu.

I do want a tune for my Focus but for better power/mpg with bolt-ons. Its not required to toggle off the traction control. Similarly I'm sure abs can be toggled off either in the menu or by fuse pull.

The traction control defeat does not remove the stability control and there is no way to get rid of the annoying torque vectoring nonsense. Turning off the traction control is a step in the right direction, but I want to have the ability to disable all three nannies.

ABS cannot be toggled off. I actually don't want that to be taken away as it works very well on my 2001 and I assume that Ford has not taken a step backwards in that regard.

Fundamentally, I only want the brakes applied when I hit the brake pedal.

Just to be clear. The disabling of electronic torque vectoring would cause torque steering which is the numero uno complaint about adding HP to fwd. And you want that?

I agree that it should be your choice but unless an LSD option becomes available for the MK3 I'm quite happy to have the electronics there.

Even the Focus ST even uses electronic torque vectoring in leau of a proper LSD (which is quite stupid on fords part). Open diff's are generally crappy for handling and disabling the electronics on open diff FWD usually results in epicly useless levels of understeer.

Disabling stability and traction control on a rwd or awd is always a more fun. When set my adjustable swaybars to the stiffest setting and lock the electronic center diff on my wrx to 50/50 power bias its always a thrashing good time.

I believe it gives people the idea it would be fun on a fwd lacking LSD. In my personal experience I've found that opinion to be generally wrong.

Regardless, there is no way of knowing if a tuning option for the MK3 would allow for the adjustment or toggling of the traction and stability systems in the focus.

It would not cause torque steer. And who said anything about adding HP? Finally, torque steer is really only a complaint from ignorant people who watch too much Top Gear or read too many magazines. A modicum of skill at throttle modulation will make torque steer a non-issue in a well designed car such as the Focus. Now, if you plan to have ST levels of power and use the accelerator pedal like a light swtich, then sure. But I am not nor ever will be that way.

The car has an MTX-75, does it not? So is it not safe to assume that the existing LSDs for the Mk 1 Foci will work? Unless of course you made the mistake of buying the car with the wrong transmission, I think this is a moot point.

I have 3000+ miles on race tracks* in an open diff FWD car. I will form my own opinions on this matter, thank you. I prefer an LSD, but it isn't a requirement to have a good time. What is a requirement is a car that turns when I turn the steering wheel, not turns only when the computers decide it is OK for the car to do what I am telling it. No one who has driven my Mk 1 Focus on track without or without the LSD complained about "epicly useless levels of understeer." In fact, most people tell me that they have to dial back their turn in because the car rotates so well. I am 100% confident that I can configure the Mk 3 to do likewise once it can be convinced that I don't need digital hand holding like some child crossing a street for the first time.

Agreed. If it doesn't have that ability, is utterly worthless in my opinion. The car has sufficient HP to be enjoyable stock if the computers would just let me do it.

* - which is not much in comparison to others but sufficient to be informed

So SCT still hates us I take it?

I love the stability control on the Focus, it's great. I can give it a bit extra throttle in a corner and it kills the understeer and whips around nicely, sometimes I can even get it to step the tail out, but I do have lowering springs.

Maybe you have to tweak you suspension a bit and learn how to drive a car that basically has computer controlled cutting brakes? I know technology is scary, but it's actually pretty cool when you put down the pitchforks and start to get to know it.
