Stall in high G turn/oversteer spin
 
Last night I was doing some drifting in the rain in a parking lot and several times when I'd give it too much gas in the turn it'd oversteer and spin out and then stall. Started back up fine so I was thinking it was a sensor somewhere detecting something and shutting it down...
FRS Auto and I was driving with stability and trac off in sport mode.
Anyone had this happen to them or know if this is a safety feature or something???

Did it happen one time or could you repeat it several times?

Trac control off does not equal sport mode....

How much fuel is in the tank?

he's not equating the two; just describing the mode he was driving in. MT does not have a 'sport mode'; AT does.

u essentially pit maneuvered urself (i did it in my old Accord once). cops hit the rear of ur car to spin u out b/c when it happens ur wheels backspin a bit and it causes the car to shut off to prevent damage from being in a forward gear while the wheels spin in reverse. nothing is wrong, cars are programed to do this

In other words, switch to neutral when car spins out to prevent stall (but you wouldnt want to do that)

To follow what others said about the wheels turning the wrong direction in gear, did you clutch in when you spun? I've spun plenty of times in autocross and as long as you remember to push the clutch in the car won't stall.

See above.

I think that is just how torque converters work, not really programming, but yes.

Agreed with some of the responses above, but remember he's in an AT.

When an unrecoverable spin begins to happen in an MT, you must clutch-in when the car spins to prevent the tires from rotating backward while in a forward gear. You must hold the clutch in until stopped or at least facing the direction of travel.

However since you have an auto, I'm not sure what should happen here other than smacking the shifter to "N"... This is not going to be instinctive for auto drivers who aren't used to constantly fondling the shifter.

I think one of three things happened:
1- The ECU may have thought you were in an accident condition and shut off the fuel pump, but with as many poeple as we have trying to be king dorifto, I'd expect we'd hear about this happening more often.

2- You may have instinctively stepped on the brake when you spun out, which makes it extremely easy to lock up the wheels, and the engine died because it was still "in gear" and forced to stop rotating.

3- as you were spinning, the car will monentarily travel backwards, and a sudden reversal of wheel rotation may have forced the engine to stop.

Likely the torque converter was still locked, so the engine stalled because the wheels stopped spinning/went backwards. Not much you can do besides staying on the power or not spinning the car. With a manual you'd have the option of using the clutch to prevent the engine from stalling.

Pretty sure MT has sport and a separate traction control off.

From what I remember the auto has the same plus a useless snow button.
Could be wrong on the auto since I spent as little time as possible in the auto.

But like others have said if he spun that tightly it most likely caused the inside tire to spin backwards....
