I think it only cuts fuel, yes. But it does so by cutting ALL the fuel. It doesn't cut a little fuel, creating a lean condition. No fuel and all air is not lean....it's just air. All the PCM has to do is just turn off the injectors for a few cycles and you get less power, with no lean. Makes sense to me.

Sounds like there really is no danger of engine damage from the TCS. Sounds like maybe ford knows something about how to not destroy engines with their programming

The problem is not with a stock GT. It's when you bolt on a blower. TCS is not adjusted for it. If I could get my Shelby TCS program in the GT I'd never turn it off. I was setting the GT up in a turn, hit the loud pedal. Start boosting, fuel pressure drops, POP from the engine, Bad .... Ford should offer a modified TCS with the whipple, they don't. Not ever wanting to hear that noise again made me go home and make this mod.

im sure ford can handle programming what the stock gt can throw at it....
but for you blown guys, i would be worried about this... as i wouldnt want my hard earned money going down the drain over fords programming not keeping up with a blower

....Is the radio RED/BLK wire giving a constant 12v when the car is running or just momentarily at Start ?
It's juiced only when the starter is engaged. Depending on how you feel, there is an easier method to access a "start only" voltage wire than the red/black at the stereo pigtail. The two top-most fuses on the far right column in the smart junction box (behind the passenger kick panel) are both start-only circuits. Use a Littlefuse Add-A-Circuit fuse on either of the two fuses (shown in yellow ellipse). The fuse for this new circuit can be a very low amperage fuse, i.e. 5-amp or less. This new circuit powers only the SPDT relay in Steve's design which typically draws around 53 mA. BTW Steve, your design is excellent. It's simple and effective which is always the goal in circuit design. What's more impressive is the fact that Steve is willing to share this. Kudos, Dude!

is't turning it off in the tune much easier?

The point of this is to give you the control of the TCS switch, where turning it off in the tune just turns it off. This just makes it work opposite of the way it works from the factory, for those that want it off most of the time. I drive with mine on all of the time this time of the year, but I'm going to do this mod b/c I want it off at start the rest of the year, and I'm getting too old to remember to do it every time I get in the car!! LOL!!

The Littlefuse Add-A-Circuit fuse is a nice touch......

That's great..
One last question: is there a way to wire his mod without having to take the dash appart ? Can we intercept these wires somewhere else like near the SJB ?

Willie had the idea of adding the "add a fuse" to circuit 20 in the passenger foot well.
With one of these:
Keeps you from having to dig behind the radio..

That's OK to get the 12v start signal, and I'm sure we can find a ground also near but is the TCS signal (WHITE/PINK) near the SJB as well ? That's the one I'm lookig for ?
By looking at a wiring diagram maybe we could find where it travel and we could intercept somewhere else than in the dash ? I really hate and would like avoid taking the dash appart...
