It is noteworthy to all who aspire to use a LC-1 with EFI Live; after you consult both Innovate and EFI's tutorials-which are top notch-no flames here-That if you follow these instructions (with the LC-1's green and white grounds hooked up to your Flashscan) you must have the Flashscan hooked up to the cable and vehicle. If not, the sensor will not calibrate-trust me.
