Quick question about track prep for the quarter mile

To be honest, at my age (58) and working for the local electric utility company and driving a company truck, I basically drive a bit aggressive, but I really baby the car on the street.

To set up my question, let me take a quick trip back to 2005. I had a 2005 auto LS2 GTO and a good friend who also knew a lot about cars had me pull one of the fuses as a part of preparing my car to run the quarter. His reason was that the car had a 'memory' of how the car had been driven, and since I was going from driving like an old lady to running balls to the wall, I needed to reset the 'memory' of the car and by pulling one of the fuses, this would reset the 'memory'.

Being new to the Ford family, I was just wondering if the 2013 Mustang GT manual had some sort of 'memory' in the same context of my old GTO? When you guys go to the track, is there any prep you do in this context?

Don't worry about it.

He was trying to get the PCM to re-learn at a more aggressive way of driving.

Modern PCM's adapt to how you drive so the car runs the best the way you drive it. But they are so advanced these days that I doubt you would ever see any gains by doing this.

Have fun.

I agree with SS. The memory your friend is referring to is called KAM or keep alive memory. Your vehicle has an adaptive learning strategy that adapts to your driving style over a period of time. Typically KAM would be reset after a repair to give the PCM (computer) a clean start. You won't notice the difference and in my opinion it could actually cost you ET time at the track. I'd like to hear from someone who's tried it, hopefully I'm wrong

The old fuse pull trick was originated to clear trouble codes in GM vehicles, I used it several times in my `98 Formula. The PCM does have a driver input memmory as stated but when pulling the fuse or dissconnecting the battery it take time (usually 100 miles) for the system to readapt. So effectively all your doing is resetting it back to a default. In all my years of running LS cars at the track we never did this as track prep.
My Formula was my daily driver/weekend warrior just like my Mustang. IMO this is part of the beauty of modern muscle, exceptional driveability, and Raw HP when you want it.
