Re: Transient fuel GUFX
Well this probly explains it at least, it is something I’ve wondered about. I really don’t want to drop pump size again though.

I moved my regulator to the rear of the car to combat fuel getting too hot. I used to have issues with boiling fuel.

Re: Transient fuel GUFX
well once again I need to thank you decipha!!! the swinging afr and hesitation issues I was having are completely gone! Did you do something beyond returning the 3 modifiers and kicking up fn1321? I feel like you had do something beyond that but havent found anything even with the compare tool.
also with the fuel pump and fuel heating up talk it made me take a closer look and realize that some of my fuel lines in the engine bay are pretty close to the turbo and hotside. I used some left over exhaust wrap and DEI cool tape to insulate/heat shield them. I feel like I am now seeing more consistency with my fuel error but need to drive it some more and take some longer trips to really see.

Nope you can see with the compare is tunerpro shows all differences.
yeah every bit you can do to keep the heat away will help but being in close proximity its still going to heat up.

Re: Transient fuel GUFX
