Sport Mode Default?

Has anyone looked at what it would take to make the Tucson default to sport mode after start up rather than back to normal (eco)? Is there a way to bypass the switch somehow?

Nope not possible. The ECU engages it to normal every time car is switched off and cranked again.

My Tucson has remained in Eco mode for months. It does not default to normal when started.

The manual says that if the mode is normal or eco then it will remain like that until you switch it but if its Sport then it will reset back to normal once the car is re-stared.

I doubt you can change that unless you can hack into the car computer

Just thinking out loud here but, if the switch is normally open couldn't I just jump it out and make it closed? I guess I need to pull the switch out and investigate?

Yes, I demonstrated that behavior to myself yesterday. Thanks.

I doubt it is that simple. Pushing the button sends a signal to the computer to change modes. When the car is shut down, the computer cycles back to Normal or Eco mode, whichever it was last in, unless it was in Sport mode. Then the computer puts the car in Normal at the next start up. Like srudenko said, it would more than likely require a modification to the programming.

Yeah - most of those switches are momentary push types (SPST to use the engineering term).

The only one I have that locks in place is the 4WD lock button, other than the stalks.
