possessed car

[jake1*2011]

Hi, wander if anyone can help

i bought myself a speed passion gt2.0 pro speedo the other day, i put it into the car and set my throttle and brake but for some reason the car drives of the line without me touching the throttle, I've set my trim to zero and it makes it worse. I have to set my sub trim on the brake to 100% to stop it moving without my input!

I turn the tx off but it makes no difference, but it does make nice black lines down the kitchen floor!
