supra matt Posted July 17, 2008 Share Posted July 17, 2008 standard mate 51 psi with vac removed or 31 psi with vac still on and engine idleing. Quote Link to comment Share on other sites More sharing options...
spiderpigcity Posted July 17, 2008 Author Share Posted July 17, 2008 just to get it started. installed everything over the last few months and came to start today and nothing. turns over, but no idle. was just wondering what basics i need to set up before ryan maps it. need to make sure everything is working ok before he comes down t67dbb i meant Quote Link to comment Share on other sites More sharing options...
supra matt Posted July 17, 2008 Share Posted July 17, 2008 What ecu mate? and has ryan sent you a base map for it? Quote Link to comment Share on other sites More sharing options...
gledo1970 Posted July 17, 2008 Share Posted July 17, 2008 ryan like to map with fuel pressure set at 33psi with no vac mate. Quote Link to comment Share on other sites More sharing options...
Homer Posted July 17, 2008 Share Posted July 17, 2008 I've always been told (on here and from mappers) that Fuel pressure should be measured as a static value and not with the engine running (i.e. diag ports bridged so that the pumps run without the engine running). 38-40psi is what most people with singles are using.

SimonB Posted July 17, 2008 Share Posted July 17, 2008 standard mate 51 psi with vac removed or 31 psi with vac still on and engine idleing. That's way too high for standard fuel pressure. Stock fuel pressure is 40psi static. Which means with the engine not running. With a stand alone ECU you can use whatever pressure you want within reason. It won't start without the fuelling set roughly right on whatever ECU you have. Quote Link to comment Share on other sites More sharing options...
