I need help modo dyno

[Jhsupra]

Hi, I have a 2020 toyota supra, but dyno mode does not work when I activate it, the car in manual mode changes gears by itself.
Can someone help me?

Thanks you

What do you mean dyno mode “doesn’t work”? Dyno mode just disables the nannies so the ECU doesn’t freak out when the rear wheels are spinning but the front wheels aren’t.

And what do you mean “the car in manual mode changes gears by itself”? Just randomly or at redline? If it’s just at redline that’s more or less normal, some of our cars do that while others don’t, I haven’t found a good explanation for why that is. Either way it won’t affect things on a dyno since you’ll want to shut down before redline anyway.

Thanks for answering, when I activate dyno mode, the traction control icon that is placed on the right of the screen is not deactivated.

When I put the shifter in manual it drops all gears to 3,000 rpm Or does it stay in second gear.
