installing the SAFC and or setting the initial settings incorrectly can seriously F UCK your motor up...make sure you read the directions in both books and flip back and forth a few times to make sure you know what your doing...choose the wrong pin and you could jack it up as well...and make sure you solder the wires and do it right the first time..not black tape....asking where the ECU is on the car while installing the SAFC sounds like you may want to ask for some help first
good luck
