I bought this to turn off the afm on my truck and it does exactly that. I have also been able to read an engine code with it already as well and worked great. The reason for 4 stars instead of 5 is because it seems to mess with the truck electronics while installing the tune (dash lights flashing, service stabletrak), which I don't know if its normal or not but worries me, so I will just stick with the stock tune with the afm disabled. Autoanything was extremely helpful with the purchase.
