Practical approach:
Well, log a stock HPFP on a stock file/car and compare to your modded file with bigger pump ;-)
Hints?
Personally I just changed the radius and volume. Works well enough for me.
Pressure regulation as well as adaption close enough to a stock car.
Without very dedicated logging you can't do much better imho.

Thanks a lot! Really helpfull! I am ready for logging as soon as the file is ready, will see if everything looks fine by then. I however still have to define the maps (RQUAHDPK and VHDP) and this is not an easy job when we are talking about 1x1 maps.  Have been looking for two nights now without result. |

Send me the MED9 file you are working on, I'll take a look and define them.

I have some doubts about VHDP ... does I need to change that ?
When Yes , why it's not changed in CDLA or CDLB engines ?

CDLA/CDLB use the same pump as all other and hence have the same piston size and volume. RQUAHDPK and VHDP should only be changed when changing to aftermarket pump/internals (APR, HPFPupgrade.com, Autotech etc.). |

Ok piston size is the same (RQUAHDPK) but stroke is 0.4mm bigger.And from my equations VHDP should be 16mm^2*3,14*5,4=271,43cm^3 and not 251cm^3. What You think ? |

What makes you think that SKHDPMX would be .4mm more? |

PWM duty cycle pulse of the lpfp is at KFFLAF.
You may also want to check KFNTBKS

Has anyone managed to get the correct technical data from the pump manufactures?

you can either check them on software or measure them by removing the HPFP!
it is the same as KRKTE. If you don't know what injectors has an engine from stock, then go to KRKTE!
