Okay found this from ROBB1. I tired it and it didn't seem to make any difference. Oh well lol.
"The engine sound enhancement works similar to active noise cancelation. It suppresses certain engine notes and accentuates others in an attempt to replicate the sound of a V8. The F150 has no cabin...
I guess the original question is if the 2.7 had the ability to enable the fake engine sound. For example here is a clip of an example. It's the same sort of sound I heard on a new bronco I test drove.
I had a 2015 f150 Lariat and know for a fact it had the fake engine sound. It made a growl when you gave it throttle. I don't belive this truck had it but curious if it could be enabled via forscan just for fun.
