Will the tuning box I have fitted to the car show up on the multi scan, and if yes will it affect anything, or tell me what its up to and stuff
 
Depends on what tuning box you have , if you look at all your readings , Eg fuel pressure you can tell its higher than with it off , i have do this with mine , unplugged it , and you could tell it was lower on a bit on most ofg the readings ...

BUT NO it wont pop up saying Tuning box fitted !!!
