For the moment Im fitting Megasquirt to my S2.

The topic is about the fuel pressure. I know that standard (MFI) have a fuel pressure somewere around +5.5 bar. But what about fuel pressure in a EFI engine? I read on internet that 3 bar is the way for EFI. Is this true?

The thing is Im thinking of fitting a after market fuel pressure accurater. I want to know what you guys recomend in feul pressure.

not sure on this but id say if you fit a 2wd pump you will have plenty, an when it goes for set up they will just open or close the regulator to suit,

 

mine is 43 psi at idle hope this helps

 

ive fitted zetecs into MFI injecton cars and not hadf a problem on the std pump
