I know this sound ghetto, but im running hondata s100 with boost on the same tune for the past 3 years. Every fall the af's get a bit crispy (11.9-12.3's), and because there is no local tuner anymore, how much would a small bump in fuel pressure, say 1-3lbs at idle affect the entire fuel map? Im not overly concerned with idle and part throttle, more just wot.

thanks!

 

Yes it should effect the overall a/f ratio.

 

I know it's a tough question to answer, but how much would a small bump in pressure equate to? Anyone with past experience?

based upon your original question I am assuming you have a wideband on the car. Otherwise you would not know what the afr is in the fall. If this is true then I suggest you try bumping the pressure up a little and see what happens.

 

thanks, yes I have a wideband in the car, I'll see what happenes...I think it's finally time to up grade to s300 now
