Speed Passion ESC HELP!!!

[Chop chop]

Hi All

Got a second hand Speed Passion Gt Pro 2.0 ESC and have wired it into the car. The speed when holding throttle forward from a 7.5 motor is ridiculously quick. I have a standard program card to try and change settings but only get a dash sign in both windows.....

Got a feeling different software might be on?

I have tried to hold the reset switch for more than 3 seconds as per instructions but nothing happens.

Any help appreciated as the tyres are barely staying on when I accelerate when holding car in the air
