if you bought your chip from ebay you got ripped off so just throw it away. and yes you will do damage to your motor eventually. the honda engineers set the rev limiter for your d16z6 to be where it is for a reason so dont mess with it unless you have some serious work done that it would benefit from the higher RPM. your motor practically loses all power at the highest RPM before the rev limiter anyway so you wont get any signs of a performance gain.
