another question

i have a device that controlls my car with a 8000 puls trigger and it works from 55-155 km/h
but when i drive i never go past 140 km/h

is there a way to make the arduino make an puls based on the input puls (normaly the puls that controls the devie)
that can controll my car with 8500 puls triggers instead of 8000 (more pulses mean that it starts earlyer and stops earlyer)

thank you
peter

What is "puls"?
