What fuel pressure are you guys using on your K20a swap... also isnt the fuel pressure constant and there is no need for the vaccum line? is there anyone not usin the vaccum line....how does it work out...
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.
we're talkin about the vaccum hose that goes to the fuel pressure regulator...JDM K20 Coupe said:
