Not quite as easy as it sounds. You would have to completely disable the factory ECU to stop the protection features cutting in. The other downside as that by disabling you factory ECU you could possible lose other features such trac control, anti-theft and some body functions depending on how integrated the ECU is.
Another downside is that modern Factory ECUs are usually much more advanced than aftermarket ECUs, even including some such as Motec.
Also if the new Falcon ECU is a modern flash upgradeable 32bit unit then you are not talking about slamming a chip in there, there will be a sizeable amount of code in there (the Delphi PCM in the LS1's code is over 1meg) that has to be disassembled and decoded.
I've read on FSP that someone put one onto a dyno, and tried to increase the boost. Net result was that when it hit 14psi, it began running very lean and dropping cylinders.
I'd like to see how the people go about getting the EEEC to accept more boost. I doubt they'll be able to easily fool the computer. I'd hate to see an aftermarket solution become the only alternative - Imagine programming dual VCT, and drive by wire, automatic transmission shifts, etc etc etc...

Good luck, I'd like to see you try and find an aftermarket unit to do that stuff.
Motec will do a lot of this stuff but won't do tranny, VCT, drive by wire.
If you are pumping boost into the thing you would need control of the VCT and that's going to be a big problem.
What sort of ECU is the Ford using, is it the same basic unit that has been on previous Fords?(like the Delco on Holden 6s and 5l 8s) or is it a new you beaut unit like the Delphi on the LS1s.
Hopefully someone can get inside it quickly. But remember that it has taken 3 years to get inside the LS1 PCM (just in Australia, they had the ls1s in 97 in the US)
on a more positive note, once the ecu is cracked(ford it would be nice if you could lend a hand!) it will be a lot easier to controll things like boost, ignition and fuel ...not to mention traction control etc. i see it as a positive thing that the computer is so complex . it wont be long till companies like chip torque start modifying peoples cars....after that itll be open slather. imagine, alll the flexibillity of an aftermarket ecu and more!!!
I guess find the senser that reads boost and bleed some boost off so it registers less. Sometimes the solution is not as hard as they want you to believe.
Another EPA will froun on Ford iff their modules are obviously modded so easy.There is pressure on them to have a module that is uncrackuble.. I guesss we can learn off the rice modifiers..

Yippee - guess you computer nerds had better start disassembling the code once you find a suitable protocol to talk to the damn thing and suck the code out.
Make an electronic unit which makes the throttle act as a normal one, except electronic, ie, you push your foot down half way, and it operates the electronic servo(s) on the throttle bbody to move the throttle halfway.
Use an aftermarket ECU which can do VCT, (or similar) Im not 100% sure wether or not there is one that can do it, but as I understand Chiptorque programmed the mazda mx5 turbo ECU which the engine it runs on has similar features (once u take out the throttle variable) so im sure those boys know how to program it up, or will figure it out soon.
You may lose the electronic throttle, but you will gain much more in that you wont have the artifically flattened torque curve (if that is indeed the case)
#2
Install an extra set of 6 injectors on the intake manifold, use some electronic trickery to not only make the standard ford ecu believe that there is only 6.5 psi (or whatever it will do) running through the engine, but also to open the wastegate up more to run the desired boost level (measured from a different sensor/point in the manifold as to standard) and then use another ecu/intercept ECU to run the extra injectors as required.
Both of these would most likely be detectable / void your warranty, but seem to be relatively easy ways out of this modifying issue that is around. #2 could also be modified (however dodgily) to only include one extra injector plumbed in somewhere in the intake stream... much cheaper that way. I cant see it being a major issue anyway.
