Apart of the electronic gremlins... Just noticed that you have the Super sports. Could be that they are old, mine lost traction and became hard after two years. You can turn all the nannies of with a good tune. for example a AED tune will leave them off completly

In sport mode the nannies will definitely get in the way of a good time. Track mode has been good for me.

Don't give up on the car yet. Find the Sensor issue and then decide where you go next.

The off at 10 had to be a surprise. I imagine the computer added right rear brake at a very bad time.

Yeah, they are pretty hard, and oddly enough the rears seems harder than the fronts by a simple fingernail test.

Yeah it would make sense thinking its at 244 mph and but the rest were at 90ish and feeling some amount of G's it freaked out. Who knows. But definitely not giving up on the car. Still have some big plans.

I second the AED tune...

Nothing worse then being on your best lap... and then the cars nannies come on by themselves thinking you have lost control of the car. Though I imagine a GT350s nannies are a whole lot better then a S197.

This is very interesting...I wonder if I can use this device to troubleshoot my ABS?

Your engine swap went along with the ford control pack or a used S550 pcm?
Control pack for the motor and the stock 3 valve ecu was retained for the ABS but somewhere something isn't talking to something else because the brakes are sh!t on this thing.
 
You'll need to pull "the plug" on this car. Literally. It's under the hood on the driver's side on top of the wheel arch beside or behind the cold air box. It's the power supply for the stability control - I'd post a picture but my car's not available right now. It's just a little black plug with a jumper across the pins.

AJ showed the plug in one of his follow up videos.

I run mine in Track Mode and have no issues with nannies. In sport mode, the car decides when its OK to accelerate. I'm not a big fan of that.
