well 2in/4 out has to be it....its running but really rich.....would fuel normally need to be pulled? i noticed the car has a adj. fuel pressure regulator on it....whats stock fuel pressure on a rb25det?....also i noticed that when i unplug a vaccum line it runs fine...but when its capped off it runs like crap.....where in a stock rb25 are these lines routed to? thanks for all the help.....

well 2in/ 1 out works till it is at normal operating temps...then it just goes into safe mode....any help guys?

it idled but wouldn't rev past 4k. 3in/ 6 out, will not idle but rev all the way out and was running really rich. its almost like if you have the bov vented to the atomosphere...it just shuts off.

i do have an aftermarket piggy back...apexi safc 2. i put the z32 afm on because the stock one was missing from the motor. the car has more parts waiting to be put on, but i want it to run good first.

on a second note the car has only a dowpipe and a catback exhaust, and now the z32 maf.....hell the car is still running the stock side mount cooler.

First off Hello, I'm in need of some help and advice. I'm from the United States, where sadly we were not blessed with the skylines like most of the world, but we can get the motors fairly easy. I have 95 nissan 240sx (silvia) with a s2 Rb25det swapped in. I've put a z32 maf in it and now i can't get it to run like i want. I'm using a safc II to correct the input/ouput signal. That is what i'm having an issue with. I've been told 2 in 4 out, but thats not working, it runs crazy rich, and won't idle. with it set to 0 in 0 out it will drive fine and idle fine till it warms up then it won't idle. I need some pointers. im getting to my buddies dyno sometime next week, but need help in the meantime. thanks.
