Title: fuel pressure @ 0.9 bar boost
Post by: wierdo on March 09, 2009, 09:07:31 pm

Hi all,

I have a chip with a map for 68mm pully. My question is, what has to be the fuel pressure matched to this air pressure (0.9 bar at 68mm pully). Is this new map enought for correct AFR, or there have to be more correction with Adjustable FPR.
I do not have AFR tool to see the actual AFR, but i have a feeling the car is running poor. No other mods.
What have to be the fuel pressure on stock G40?
What have to be the fuel pressure on G40 with 68 pully?


Thanks

leave the fuel pressure as it is and let the ECU sort the fuelling out.  No need to fit an adjustable FPR, wont do any good.
