I've seen brian g mention a few times, that hooking up the vacuum line to the FPR will make the K series ECU "freak out"???K20DC2R said:do you guys have idle problems? mine coming to a stop idles high then lowers after a couple of seconds....does that happend to you guys without the vaccum hooked up?
same as mine i hate that shhh.... the k20/k24/d17 are supposed to run high constant fuel pressure..... how was cmi neil?? good job on the 12.1.........props!!!!allmtrallday said:i run with the vacum line fuel pressure is set about 60psi. runs good. sometimes idle will get about 1200-1500, and drops as soon as i come to a full stop.
wow nobody has answered this yetJDM K20 Coupe said:which vaccuum line are you guys talking sbout disconnecting? the fuel pressure one or another one? should you leave the line open or plug it up?
we're talkin about the vaccum hose that goes to the fuel pressure regulator...JDM K20 Coupe said:wow nobody has answered this yetJDM K20 Coupe said:which vaccuum line are you guys talking sbout disconnecting? the fuel pressure one or another one? should you leave the line open or plug it up?
yup! thats what everyone will find once they hit the dyno! :wink:katman said:I'm running 60psi thanks to RyanR's dyno results (gained 5hp by raising FPR to 60psi).
Using an SX fpr and no vaccum line connected to vaccum nipple.
