When in realtime SFC mode, what does it mean when the display flashes "OF"? If I go WOT in say 5000-6000 RPM range it flashes OF at certain points in the powerband. The fuel settings at these points were only at +1-2%.

 

It's telling you that injectors duty cycle is maxed out.

You can raise fuel pressure by using fpr.

I figured thats what it meant. But how can the injector duty cycle be maxed out at only +1-2% ? Could it be that my Fuel pressure reg. is set too high? Or am I running to rich already?

 

What is your fuel pressur set at?
Stock fuel pressure on si is around 40psi. Right?
On ITR, it is around 48- 52psi.
Si and ITRs use same injectors as well as fuel pump.

 

Are those pressures with the vac. line on or off the fuel pressure regulator? With the vac. line on, my reg. is set at 36psi, with it off its at 46psi.

Also, when it says OF, is it supposed to have a constant OF once you reach that RPM range? Because on mine it just flashes on and off like once or twice in that RPM range.

 

line off.

 

Is it possible for the injectors to be at full duty cycle at just +1-2%

Also, take for example these settings.
0-1
0-2
0-3
0-4
+2-5
+2-6
+2-7
+2-8
At WOT, when it reaches the 4000 RPM range, it displays 1-4 then 2-4 then it goes to 5000 rpm range and stays at +2, even though I didnt set anything for the 4000 rpm range. Is this normal?

 

anyone?
