I suffer from the hesitation problem, and I had a thought, but I'm probably wrong.



Would the ECU cut fuel at 0.5 bar? That's where I'm currently peaking at and I only get the herky-jerky hesitation when I'm at full boost.



Maybe an FCD would help?

 

Probably, my boost doesnt cut off until almost 9psi, then I need the FCD.

 

mine cut out ar a little over .5 too

 

S4 fuel cut is supposed to be 8.6 psi or 0.59 bar.

 

then maybe it is 8psi for me

on the gauge it shows 9, but it is autometer.

 

well, the guy who owned the car before me installed the guage pods on the passenger dashboard, so it's kinda hard to look really hard at the boost guage whilst blasting down the boulevard.



footnote:

I understand that the current location of the guages is gay, but they have damaged the dashboard, so removal isn't in the cards right now.....but I'll get to it.

 

I thought the s4 cut fuel @ 7.5 or 8 psi. Atlease that is what my s4 does. My autometer reads 7.5ish when the fuel gets cut.

 

heilige Scheiße!!!!



I think I've found my problem! Now I need a FCD.



Who wants to sell me an S4 FCD?



I needs it!

 

the autometer guages arent that accurate, ive seen a 2psi variance between them

 

Build your own FCD. I did and it was a breeze.
