Why doesn't my Coyote F150 pop and crackle like my Mustang did?

 

Valve timing and exhaust system. KM

 

Can the tune change the valve timing and add a bit? Just a little...

 

Yeah, look into "popcorn" or "crackle" tunes. If you want your engine to sound like it's not being well-controlled by its computer.

 

I kinda miss it a bit...

 

In the days before variable valve timing. It took a cam change to change the amount of overlap and duration. So called 'big cams" featured more of both and subsequently had a characteristic idle lope and produced the crackle/pop, particularly with increased compression. KM

 

I was about to respond but realized I posted all the info here:

Ate you telling me my truck has dfco?

 

Without even looking at the cal, I would say most likely yes.

 

5* can shut it off, I assume?

Or is that a Forscan thing?
