Not on any of my companies vehicles. All Fords. And my old Taurus. Never any issues besides from the dealership being busy.

Not sure, but some people on here seem to enjoy telling others to leave their cars in stock form.

Just educating everyone; gone are the days of being able to tune/flash the ECU and then reflash it back to stock if there are issues you want taken care of under warranty...the new software can and will track if the software has been altered and that is all dealers need to do to deny warranty work.

I modify my cars and understand the outcome of my decision, just want everyone else to know as well...no uproar!

I know. My car is still new. I don't plan on doing anything warranty damaging for a little while.

Yep I ran into this on my Saturn, and GM has a flash counter on their ECU's that if a tune is flashed using anything other then a tech 2 device it tripped the counter. I took my car in once and asked them how many times I had tripped it and they laughed saying it was 30+times it was tripped.

My dealership didn't care they did the work because they got paid to do it, but some dealerships are stricter then others.

I think with the state of the economy and the tightening of the belts have led to stuff that the car companies were once willing to do are gone...and I am ok with that, if I install something on my car that exceeds the OEM specs I would not want the dealer to pay for me stupidity...gotta pay to play and if you can't afford to replace parts tread lightly!

This. I enjoy turning wrenches and I'm not overly concerned with my warranty. You also can't expect me to drive 60k miles before modifying something. I have barely driven that in my life but all my cars are modded. If I break it, I'll fix it.

It is a true statement that only an idiot changes the tune on a car before the engine break-in period is over.

Having said that I bought by Focus 5spd used with 20K on it. Break in period is over. Time to program more fun into the ECU.

In a high compression direct injected engine with VVT thats been tuned for fuel eco there is no reason we cant safely make 200hp with header, intake, exhaust, and high octane. Maybe 215 with a better flowing TB, IM, and if we make it that far - larger injectors. Thats all without a supercharger or turbo kit (a turbo kit is kinda pointless with the availability of the ST)

Its really a question of what the transmission can handle. Without tuning options we will never find out.

With the old 2litre DOHC zetecs in the escort ZX2 people were cryo-treating gearboxes and diff's and finding mad ways to fit LSD in place of the bullsh$t oem glass open diff.

Transmission upgrades are pretty mandatory with any significant upgrade in power output.

There is probably a viscus or clutch type lsd that will work in the focus. There has always been aftermarket options in prior year models.

The problem as I see it is the DCT. Its new and has its own issues in part because of bad factory programming and in part (as I read it) with programming unable to deal with contaminated clutch discs from leaky rear main seals.

From the factory the DURATEC Ti-VCT is supposed to put out 160chp. A couple of DCT people seem to be ok with untuned boltons putting down 170ish whp. Lets conservatively assume that's an extra 20hp over stock. What is the slow-shifting DCT going to do with an extra 40hp over stock or 60hp over stock?

Is there a viscus LSD that will fit the DCT? I have no idea. I dont have DCT so I haven't looked into it. I may look into a viscus lsd for my 5spd

From what I've read the focus is supposed to have an electronic brake biased traction control setup to compensate for the presumably open diff by applying the brakes to just the wheel slipping to transfer power to the wheel with traction.

This sort of system is clever because its cheap and electronic and runs off of ABS computer in most of the implementations I've seen. However its electronic and may has no programming to tell if it is actually behaving appropriately when subjected to more HP than it was designed for.

Without tuning options the nightmare of insufficiently strong transmissions is a world we currently will never have to see.

Having said that, these are problems I would much rather have over the issue of no tuning.

20 hp from an ECU flash on a 2 liter N/A engine? More like 5. Don't believe the hype from CAI and exhaust companies. My Spec-V SER gained 17 total with CAI. header, exhaust and balancer delete. 5 hp gain with a Jim Wolf ecu re-flash on a SR20DE SER.

And, that engine isn't DI, either.

Not to mention, every engine has a different response when it comes to tuning.
