Fightpad PCB turbo function issue


Hi all.
I have a ps3 fightstick TE dualmodded with a xbox360 fightpad PCB. Yesterday i was playing in xbox 360 mode and the turbo function turned on randomly (on X and Y buttons). I have unassembled the fightstick to release the xbox 360 PCB and when i plugged the pcb into an USB port i saw that TURBO function was always active (the red led blinking) and the Y button is always pushed. How can I erase or disable the turbo function? Thanks in advance.
