Focus LX E.C.U. question?

Hey all,

I'm new to this board and I'm actually not very good with cars, but I have a question. I have a friend that tends to lie about a lot of ****. He said he put a Focus SVT E.C.U. that he bought off of Ebay and installed it into his 2004 Focus LX. Can this be done, and if so will it give it much of an increase in performance? Just trying to call him on one of his many lies. Maybe he's not for once, but I want to know for sure. Thanks!

I'm unsure wether it is physically possible or not, but he would NOT have the power of an SVT with only the PCM (ECU/EEC).

the power of the svt comes from teh motor, not the computer, ifteh computer was put in his 04 then the computer would be so conused it would have NO idea what to do, if anythign it would slow him IMO

No, it will not work. That computer will be looking for things that are not there. The SVT runs a different compression ratio, dual intake manifold, VCT.
It may plug in(I don't believe it would) but would not funtion properly, if at all. Even if he could get the computer to funtion(doubtful), it would immediately go into a "limp home mode" without the feedback from the SVT sensors. The computer would be looking to run timing for the higher compression and when it runs that timing, it would get deto. The computer would think the servo for the dual stage manifold was broken.... With no feedback from the VCT it would think that was broken too....
So it would either 1) not run at all, 2) pull lots of timing and add fuel(dropping a minimum of 10whp) or 3) run only two cylinders at a time(overheating/limp mode).

Anyway you look at it, he's not running a SVT computer.

Thanks guys. I think I have enough to call him on it now. :biggrin: He's always pullin s*** on me, and this time I really had no clue. All of this car stuff is really awesome though. Maybe I'll read up on it some more. Any links you can give me? Thanks.
