This is my final config for a demand of 130bar (with internal integrated engineering 155bar kit for safety + latest hitachi HPFP ref) and RS4 rail valve.
Engine CDLD.

KFPRSOLHKS = 130bar
KFPRSOLHMM = 130bar
KFPRSOLHOM = 130bar
KFPRSOLKH = 130bar
KFPRSOLOFF = 0bar
KFPRSOLSCH = 130bar
KLLFPRSG = 130bar = 0,509716
KLPRMAX = 130bar
VHDP = 407,32
RQUAHDPK = 24,01
SKHDPMX = 5,4
PGBDVHDO = 136bar
KLPROV = 136bar
PRNL1 = 130bar

What do mates think? something more to touch up?



are these infos about the IE hpfp kit valid?

i don´t get any feedback from IE directly for piston size, 9,8 seems not really much to me compared to the autotech and VIS kits...  Huh

of course it is correct. but you have to take into account if your engine code is CDL or earlier to make the calculation. change the diameter of the cam.

i know the calculations, thats not the thing, i was talking about the mechanical part.

inbetween i got an reply from IE directly, they´re saying the piston size is 22,225mm...

22.25 is similar to the piston that uses APR about 9.5mm. The rest of brands autotech, kmd, vis, integrateed ... use piston of 9.8mm = 24.01mm.

IE info HPFP:

It is the bomb that I carry.

"Our pump will be perfectly calibrated with any ECU calibration which is tuned for a 9.8MM diameter HPFP piston, which is commonly available."

Going by your KFNTBKS, you'll spend most of your time in the 500-580kPa range for which you don't appear to be running enough duty cycle. I hold 5.7bar at the red line in block 231 with the following attached.

Also, you'll need to limit your duty cycle. I've found values above 82% will cause controller cut. 77% has enough safety margin and the pump has no problem supplying the required fuel.


Hi gman86. So these to maps are targeted maps for the lpfp?

Yes. KFNTBKS and KFFLAF are LPFP maps.

I use 3.6 BWS engine with stock tiguan LPFP controller and pump (same as RSQ3 controller and pump). Here are two KFFLAF maps, tiguan map is above and 3.6BWS is below. Do I need to change number in the field or change axis too?

And I opened three KFNTBKS maps: my 3.6 BWS MED 9.1, 3.6 touareg MED 9.1, Tiguan MED17.5.2 (from up to down). There are different number of columns in two similar maps (bws and touareg). Is it normal? Do I need just to transfer numbers from tiguan map to my one?

Hi to all. So the HPFP map is it also a target map then? Can some maybe share there RS4 injector maps and explain the axis function for example x amount fuel pressure at spesific rpm and load points?

So what maps needs to be adjust to fits the TTRS LPFP in 2.0 tfsi ?
I am having fuel cuts now at high rpm and error on lpfp.

It depends on what the code is your throwing... Provide more insight into your issue and we may be able to help.

It'll be low pressure regulation because low pressure drops off when the controller does its thermal cut.

KFFLAF needs adjusted to rework the pump duty cycle. You need to limit RS3 pump duty cycle to 82% to avoid thermal cut at high load.
