This the error mess,
Arduino: 1.8.1 (Windows 7), Board: "Arduino/Genuino Uno"

C:\Users\antevo\Documents\Arduino\sketch_jan13a\sk etch_jan13a.ino:9:17: fatal error: LCD.h: No such file or directory

#include <LCD.h>

^

compilation terminated.

exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Hey the 4.7k ohm resistor that goes to the Flex fuel sensor, can it be wired in further down stream or does it need to be wired in at the FF plug wire,,
Thanks,

my resistor is soldered directed to the board. The pin 8 wire can NOT come before the resistor

Great mod and cheap too.
Any chance you can get some e98 to see if it will accurately read above 85%
