efi trouble
 

i have been trying to tune my buddys lly. i had to buy a new license todo this. because i have already tuned 2 trucks. but i cant get his computer licensed or something it wont take a tune and i cant remember how i done the last one. i have already put the license into the tuner but i cant get a tune to go into the truck. any help?

run efi as administrator see if that helps.

you might have to register that new license you bought with you buddys computer if your using his to flash the truck

well i figured out what was wrong. my buddy was cheap and bought a cheap wiring harness for his cdplayer. now he has to take the cd player out every time we tune it

just pull the fuse, even better all the accessories put them on a switch :U:
