I'd imagine a tune is in order. The TC will probably freak out correct? Is there a tune specific to this?

Hmmm good question, can't recall if anyone has run into a problem or not.

Most people get a tune with their FI setup or something similar, but I'm just getting the LSD to start. That opens up doors everywhere from FI to NA. I'll shoot TurboTom a PM.

Wouldn't the LSD keep your tires from spinning so why would that freak out the Traction when it only monitors tire slippage anyways? You can always run a TC Kill switch if you just want to do burn outs.

I'm going with the Torsen because it's legal in SPEC Focus. I'm going to slowly make the car SPEC as I progress in my fiscal growth. Ha!

Orange, that sounded rather "cheeky". What I'm worried about is that the change in differential may cause the TC to react one way when it doesn't need to now that the LSD is in place.

In regards to burnouts, I'll leave that to you and your turbo.

I'm sure that if the TC would freak out, there'd be hundreds of "My TC freaks out after LSD install!!!!1!" threads popping up since the SVT/Traction Control has been in the focus. Try a search next time if you don't want "cheeky" answers(what ever that means).

And to your last comment, who says I do burnouts or even have a turbo. misinformed... [dunno]

Besides if you are concerned, once you get a tune, it will totally deactivate your TC when you push the button.

TC will still work fine with the LSD.

I think that the issue about REAL lsds was done for good. TORSEN = Torque Sensing Differential... LSD = Limited Slip Differential. So a Torsen is not an LSD... anyways, how would they know (spec guys) what type of differential you have installed?

Traction control on the focus pulls timing when it sees wheelspin, its a completely independent system of the mechanical aspect of the transmission. If your tires slip and lose traction even with an LSD and your T/C is on, all the car will do is pull timing to "bog" engine speed in an attempt to correct.

you should be ok, i didn't have any problems with my the car, just a problem with me doing burn outs all the time. 2 stripes are better than one

Interesting... thanks for that fhg959. I'm not sure how they would check which differential I have but I'd rather play it by the book. Oddly enough, the MTX-75 is only allowed the FRPP Torsen or a Quaife torque biasing differential, while the Getrag is only allowed the OEM or the FRRP Torsen. So it looks like only a Ford Racing Torsen for me.

So... I will do a SEARCH on what the difference between an LSD and a TSD is... if that is even an acronym.

And for OrangeSVTGuy, I confused you with 03OrangeSVT. But since you apparently don't do searches either: "Cheeky" [neener]

EDIT: What does a Torsen (Torque Sensing) Differential do? Answer (for lack of better links.)

I still want to know how they know if you have a Torsen or Quiafe.......what do they do, crack open your gear box?

I'm pretty sure I'll have to keep a record. I'll ask around... Quaife would be nice... but dang... it's about 400 bucks more! I'm looking more at a track car vis-a-vie Spec Focus. There has been talk with my close friends about a rally-X or rally car, but from what I understand, it's expensive, more so than a track car. So we'd either stay clear or use one of our Sentra SE-R's for the job.

They jack the front end up in the air, and rotate one of the front wheels.
If the opposite side rotates in reverse, it's an open differential.
If the opposite side rotates in the same direction, you've got an LSD or ATB.
Yes...they can find out pretty quickly...

The quaife is an ATB, and they woul let him use it. How would they know if he has an LSD?

I'll do some research right now. :) Get back to you guys asap...

My real question is this: Is there a performance difference between the Torsen and the Quaife that they wouldn't allow the Quaife in the SVTf?
