Okay, so I started it up after installing my s-afc2 and my 370cc injectors. It idled like complete ass! Also, the RPM signal is abviously off, since my rpms where way low and didn't climb with the tach. Anyways, after afew minutes it started to idle a little better, but then I reved on it to see what whould happen and the rpms jumped to like 4K and then dropped very slowly to around 1500 without even being on the peddle. After it dropped back to idle, I shut her down. Now she doesn't start. I checked the plugs(which were brand new DENSO'S) and they smelled like gas and looked pretty wet and black. Think I just fouled out or what?
Failure is not failure if you learn from it
umm, did you compensate for the larger injectors?
Yeah, I would say that you did foul your plugs.As for the rpms being so low I don't have aclue what that could be because I have the same problem.
My rpms on the s-afc2 are like 400 rpms lower than the actually are(at idle). And they are like 1200 rpms off when I rev it. It will show 1200 or so aon teh s-afc and around 2500 on my tach. I guess I need to rewire the rpm signal since all my other signals are right. What do you guys think I should do?

Yes, and it is set to CYL 4.

Do you think that will help the rpm crap, also do you the think the plugs are fouled. I only ran them for about 10 min.

Also, I checked all my pinouts and the only wires going/coming of the ICM and coils are the IC timing control, IC timing control(B), a ground wire and some reference wires. I hve my rpm sig hooked up to the first IC timing control. I don't know WTF to do!

cylinders 2 with arrow pointing to top right. rpms should be fine. U might have fouled ur plugs. try putting low throttle to -35 and dumping ur Fuel Pressure to like 37. should start to idle then, somehwat.

Are you trying to run low impedance injectors on a high (saturated) impedance system?? If so then that is what's wrong. Get resistors, and you will not have problem anymore.

The injectors are rc 370cc hi-impedence injectors, 14.4 ohm I think. I have the 255lph intank pump, and stock fuel regulator w/ an adjustable reg as well. I turned down the other reg, since that is only adding pressure. I plan to buy the accel stock style adjustable to help base pressure. I am also about to go out and get a bunch stock plugs for now till I get it all tune, since I blew my denso's.(12 bucks a piece
) I will post if the setting you guys suggested help any.

What resistors are you talking about? I have a 01 Z with brown tops in and no resistors why would they be needed? Let me know because I would like to fix this if its nessesary.
