#100495, "no one knows"

i have a 95 420A talon with a hahn stage2 fmic turbo kit on the car when i bought it. ill list what the car has and what it does if anyone can help id be so thankful. the motor is stock with the turbo kit that was on it and an in line fuel pump with the fac pump.i put a new 12:1 fmu on it. it has a mp 60mm tb. msd coil pack,plx wide band air fuel meter, new narrow band o2 sensor running to the fac wiring with 3" exhaust from turbo to muffler. the car runs pretty good if im on flat or little down hill grade but as soon as i hit up hill or just need alittle bit more power it sucks. it will hit 3-4psi boost fuel pressure goes up but wide band is reading 14.5 or so and then it just goes off fuel pressure will drop 10psi and the wide band will go straight to 11.3 and the car will scream. any ideas. sorry so long

Agreed. That's why my car did using the Hahn FCD and no Missing Link.

OP, what are you using to trick the MAP sensor?

Yeah, lemme take that back. *I* have a 95, I should have remembered that. Boneheaded on my part.

It should like you're not getting the fuel pressure up fast enough. Can you verify the fuel pressure is increasing consistantly with boost?

100 psi? Do you have your fuel return hooked up? I know it is stock on your year.

Also I have a 95 and I had an electrical issue running two fuel pumps. Both wouldn't run at the same time. I did the fuel pump rewire mod with an added relay in the rear and it fixed the issue.

Fuel filter could also cause issues.

Ok...let me get this straight:

When it goes crazy...the fuel pressure drops like woah, and the wideband falls to 11's which is richer emoji

Some would argue that the fuel pressure dropped because it was flowing out of the injectors making the mix rich.

good point, possibly hitting full duty cycle? Injectors just staying open?

I would be curious as to what this means:

plx wide band air fuel meter, new narrow band o2 sensor running to the fac wiring

I don't know everything but what is a wide band meter? What kind of new narrowband? What is FAC wiring?

I would also be leary of the 12:1 FPR. There are a lot of faulty ones around that people replace with better ones and sell the old 12:1 off. Where did this FPR come from?

How did it run before you did the o2 sensor install and move?
