2013 Focus ST and "Tuning Protection"

http://www.sharkperformance.co.uk/ne...cle.asp?id=129

Long story short: The 2013 Focus ST uses a Bosch MED17 for engine management. The latest generation of MED17 (with the Infineon TriCore processor) employs "Tuning Protection". For those that are computer literate, a 1024 bit RSA signature is used which is virtually uncrackable.

In various searches, I have found some tuners that do offer a tune for cars with the latest version of the MED17. However, there is one problem: The PCM must be removed from the car and sent to the tuner. To reprogram it, they must remove the cover and use a special jig to connect to the PCB.

Also, it seems that Ford is really cracking down on "mods".
Here is a quote from TSB 11-7-7:

Some 2011 F-150 and 2011-2012 Mustang vehicles equipped with 5.0L engine may have unauthorized modifications to the powertrain hardware and/or calibration which may result in exceeding component design limits. Such modifications could cause damage to the powertrain and/or void the factory powertrain warranty.

There is also is flowchart that instructs the tech to initiate the warranty cancellation process if it is determined that an aftermarket calibration (tune) was used.

FYI, Chrysler has already has "locked" their PCM for the SRT-8 vehicles.

http://www.lxforums.com/board/f155/p...t8-pcm-279857/

Perhaps more and more car manufacturers will "lock" their PCM's. I have seen many people stating that the Magnuson–Moss Warranty Act puts the burden of proof on the manufacturer. If someone were to use an aftermarket tune that damaged their engine and removed the tune (i.e. "flashed back to stock") before having their car towed to a dealer, is it possible to definitively prove what the cause of the engine failure was? If not, this may be the reason why car manufacturers may want to protect themselves.

If aftermarket tuning is not available for the ST, would it affect your decision to buy it?

I wonder if they'll use the same anti-tuning ECM on the non-ST... I was planning to put a bolt-on turbo/supercharger once they became available.

electronic companies always have the stickers/seals on certain parts saying if this is removed, warranty is voided. So if they put some sort of anti tamper device on the ecm.

buying a car that cannot be modded would def not interest me... i mean i'd like to categorize myself as a car enthusiasts, and if i purchase a car even tho it may be already fast or look nice, first thing i do is look at available mods for it. But im sure like every electronic there's a way to bypass it.

Good thing I've already decided the new Focus models aren't for me. Well and most newer cars for that matter. Too much junk and not enough enjoyment. The days of just buying a car with a decent stereo are gone now I have to have TCS, ABS, Stability control, navigation litigation and frustration. Hell with TPMS and all kinds of other stupid electronic add on things it annoys me.

Lame. Tuning my Fusion couldn't have been easier. Plug the xCal in, push a few buttons, wait. Done.

That may be true but at the same time you shouldn't assume that it's a done deal. SRT-8 owners wouldn't be up in arms if they had a tuning solution.

1024 bit RSA is not crackable, so it means that the tuner would have to find and exploit some kind of vulnerability to enable access thru the diagnostic port.

One possible (and not so unlikely) scenario: There will be a tuning solution, but not until sometime in 2014 at the earliest.

itll be limited but you can prob still tune it in some way. Same thing used to happen with my M-Xrs... 1st gen ECU of that kind was in the 2000 celica gt-s and still to this day it has never been cracked. But with a power FC stand alone/piggy back it can be tuned to about 85-90% its potential
