I have a smog appointment on thursday and i was wondering what the exact fuel pressure is supposed to be and what the timing is supposed to be set at. I think it is 32psi on the fuel and 10 degrees timing, but i don't know if that is with the little chip thing on or off. Any info will help. Thanks

if i remember correctly, Ford's oem setting is 12d timing when you disconnect the "littel chip"

OEM timing is 10 degrees. Not too sure about fuel pressure but 32 (vacc off) sounds close.

I just had my fox smogged at it was set back up to 10.

I had the stang smogged on thursday and it passed with flying colors. I left the timing at 12 degrees and the fuel pressure at 45psi and the smog guy didn't even check and it passed great. i also only have the two cat x-pipe setup from BBK.

hey dude, what is your setup(mods) cuz my 93 with h/c/i passed easily, at 12. if you are close to stock mods, you should pass with no problems, make sure o2 senors, egr vacuum lines are correct, tb colant lines are connected, smog lines are hooked up, clean air filter and good gas you should pass, if all cats are good. this was before i had lontube headers, what do you have(headers, h-pipe)?

The mods are:
10 to 1 compression 306
trick flow twisted wedge heads
E-cam
polished typhoon intake
30 pound injectors and Pro-M mass air meter
1.6 roller rockers
70mm throttle body and egr
bbk cold air intake pipe
I ran the fuel pressure at 45psi and the timing at 12 degrees with the little chip disconnected and it passed smog just fine.
