is there a need for check valves with the safc?



i'm only going to be running like 8 psi?

2bar map? how would i set the safc with something like a GM?

help please

i really would stay away from the check valves, and get a 2bar map from mr2oc or alltrac.net.
with the 2bar map, use injectors that are around twice the size of your stockers.
IIRC the 7a injectors are around 200cc, so somthing around 360cc or so would give you enough fuel for just over 200whp, and would work in tandem with the 2bar map.

so if i get some injectors twice as big...would i have to use a FPR ?? because safc can't control something that big right? well right now i have the yellow top(305cc) i thought it was high impendence since it gose on 7mge 88-? ....it could be high but i read somthing else and dont know if they are right?

hey p2.....thats your new nick name.... you know anthing about my last thread about yellow top injectors?

you think if i'm running like 6-8 psi my MAP won't throw a code?...i put a WTB in the mr2 site.

Hey dont mention it. I'm just doing my part in the world

I use check valves and havn't had any problems. I didn't know you could use a 2bar map for a 7a? It wouldn't throw a code?

if you're using a 2 bar map, don't use check valves...

wow well we need to clear this up

check valves work but...... if you can fit and get a 2 bar map to work fine with your ecu that would be the better route
