here you go http://www.nissanversaforums.com/general-versa-discussion/17186-nissan-versa-service-manuals-owners-manuals-parts-catalog-software.htmlHey guys, can someone please get me the diagram for the fuel system on a 2014 Nissa NOTE? I need to tap into the fuel pressure regulator but can't find that little booger anywhere. Any help appreciated
So if thats the case I should be able to enter my PCM with the Nistune software and boost my pressure, correct? Should also be able to adjust timing.That is a general description for a conventional multi port return fuel system with a vacuum controlled regulator, that will vary rail pressure based on MAP. Returnless systems do not compensate for manifold pressure by using it to modulate the fuel pressure, they maintain a constant pressure through that regulator. Now can you modify the stock regulator to output a higher system pressure? Probably. But understand that in most returnless systems, rail pressure is static, and compensation for injection volume differences at different pressures is done through the PCM with multiple sensor inputs (MAF, TPS, crank/RPM).
