Is there a way to set maximum speed so whoever drives the car can't go passed a certain speed limit?

 

One word: Nope.

 

Disconnect the mass airflow sensor.

I think maximum speed is crawl.

 

yes, no valet lolz

 

Simple tricks are the best tricks.

 

You got instructions on how to do that?

 

dash cam...boom...

 

***Edit:***

nvm

 

My trick for valet mode is to set my Apexi throttle controller to "white" (Eco mode 1). Also, if you leave it running when they take the car then throw it in Snow mode too. This won't limit the top speed, but it'll make it a lot harder for them to drive it like an idiot.

 

Good idea, but passive.

 

Just don't valet. Drop her off at the door say "hey honey I will be right back, you know how this works. I wouldn't let another man drive you."
