Fuel economy has gone down slightly, it's definately not gone up.
Standard fuel pressure is 3.5 bar
It came set to 3.0 bar which is the recommended setting for 440cc injectors, without the spacer it's maximum is 3.2 bar, to get it any higher you need to fit a spacer, but this then means you can raise it up to 4.5 bar, so without a gauge there's no way for me to check the fuel pressure, so my only option is to refit a standard pressure regulator and see if i get any changes.
ETA, as for the closed loop, this is the problem i think, with the pressure drop the injectors aren't as efficient at atomising the fuel, therefore it's putting more in and running it rich. |
