Here's a small update:
My OBX FMU was nothing but trouble. Besides the fact they come from the factory needing some modifications to function correctly, mine was missing part of a gasket, then this small metal disc that restricts the flow of fuel got a hole punched in it from the piston.
The theory of the FMU is solid, but poorly executed. With quality materials it would probly work pretty well for more than a week.
So after trying various ways of band-aiding that thing back together, I said to hell with it, and dropped in some 550cc STI yellows. I know what you're thinking; it's gonna run pig rich.
Well, it did. But no problem, everytime I've tried to plug in my o2 sensor it causes the engine to run crazy lean. Like won't even idle, 19:1+ afr's lean. Hopefully that will counteract the oversized injectors!
...Nope. Still runs crazy rich with the o2 plugged in. Ok last resort time. I've taken a leaf outta Reddevil's book and wired a potentiometer into the MAF signal line. If you haven't read his thread, it's AWESOME! Installed my supercharger today! - NASIOC
He apparently used a 50k one, all I could scrounge up were a 100k and a 500k! Dropped in the 100k, and nothing with the o2 connected, but disconnected it works like a charm! Turn the knob and my afr's climb! YES! But it wasn't enough, I had to switch to the 500k to get (more than) enough adjustment.
So now I've ditched the stupid FMU and just have 550cc injectors and a MAF pot, and my car is faaaaast! Well it is when the clutch holds! It will slip as soon as boost hits from 3rd through 5th, and sometimes in 2nd
that's what 11.5 psi gets me.
But damn she moves!
and my AFR's are right where I want them in boost if I'm just slightly rich at idle, or I can lean things out for long cruises at constant speed. This seems too good to be true, but my EGT's and AFR's are excellent, so I'll roll with it. Boost is 11.5 psi now and no sign of detonation.
Also installed my CF hood, jeezy petes it's light! Pics this afternoon.
