will this chip disable the "pats" system 

Asked by: shawnpaul459
I don't believe so. From what I understand, this only affects performance variables.

My question is can you flip it on the go without the check engine light coming on and causing the car to run like poo? if not my problem is fixed, if the chip is designed to do that what do I need to do?
