xecuter2 lite and external sw errors

[satd153]

have an xecuter 2 lite running great for a few days. today i installed an external sw. to disable the mod chip. i also have evox installed. the problem is if i cold boot the xbox with the switch off )(mod chip disabled) i get error 13 with the damn contact support bs. turn the switch on and reboot and everything is ok, back to evex dash. is this normal? how do i use this switch to properly disable the xecuter2
