HPFP pump configuration

Post by AndreyB »

I own three different GDI vehicles and both inline 4 happily start on rusEFI.

Both vehicles use original default settings are based on BMW design, at the moment the only difference between the calibrations is Volkswagen 2.0T has three lobes on the cam while Kia has four.

HP Fuel Pump HDP 5 says "Max. 1.1 cm3/rotcam" huh why do them mention rotation of cam and not per lobe?!

Do we care to properly measure chamber diameter on different pumps / cam lobe stroke? Do we care to properly measure Hyundai cam lobe position since we kind of anticipate dozens of these vehicles _soon_?
