everything went well, only problem I had was the instructions don't say the car has to be running but it does have to be running or the +2 won't hold... without the car running it'll still tell you sucess when you do the +2 but then when you go back in & check it's still at base timing, didn't notice this till like the 3rd one & had to go back & redo the first ones, then check & confirm it held, so yeh, car must be running.
we did a total of 6, 5 fx's & I had a freind with a 350z who I also did... cipher should ship out monday to canada...
also fyi, I had the +2 done on my fx over a year ago & have since reset the ecu several times & had my battery off several times. I hooked the cipher up to my car to see if the +2 was still there & it was, so this +2 is not volitable & won't just go away on you for just a dead battery or an ecu reset...
