I have no logs because I have a boost gauge (makes things easier)

Why would you say that..
New values inside maps should be
424.11
And 25 for other map
Based on having a CDLx engine code

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: https://performancebyie.com/products/ie-hpfp-vw-audi-20t-fsiIt 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." I emailed vis it's a 10mm piston not 9.8mm. on their stage 1 pump. |

For those who don't know VIS stage 1 pump can handle up to 175 bar..
It's 10mm piston
So go out and get your 175 bar relief valves while your at it.

Which injectors have you tested @ 175bar actual rail pressure? and how long they can last?
Also, what do you think the MSV will say about your approach, i`m very curious.

I got RS4 injectors. I only want to run them at 140 bar though. I've noticed after 6k rpms no matter what the fuel rail pressure spikes to 175 even if command is only 140. It's like n276 valve can't bleeding off the excess pressure. I wanted to tune it for 500 crank hp for now and later on when I get an even bigger turbo go for more power and do water meth.

Hey guys
Just installed the Autotech HPFP.
I am struggling to adjust the VHDP label, since TunerPro via my .xdf file says the "total volume of the HPFP" (german: Hubvolumen HDP) is 95.36 mm3. I guess my .xdf file is pointing towards something else since the stock volume is 251 mm3.... :-( I am running 1k0907115L.
Could someone adjust that label in my file for me?
Thanks ahead :-)

Hey again, forgot to say, i am running 1k0907115L with software version 0030. got a 0010 file but they dont match up.
Found to different adresses to the VHDP label and checked my bin file,used a hex-editor, but could not understand/find anything useful in that hex-editor :-(

Hi guys,
BTW there is a major difference between the FR and the stock value of FKMAMSV...
It should be 1.5 for 3 cam lobes, but there is 3.0 in the ECU... that is a huge difference while calculating the fuel volume.
I already changed it, but don't see a difference, however the bit2 is set in CWVSTMSV.
Any thoughts?

Well my problem two posts ago is fixed :-) I am just wondering, all the maps for running with 130bar fuel pressure, how have you guys calibrated/set them? Just replaced all the 110bar values with 130bar ( and smoothend/interpolated them nice to the other values less than „130“) or only all 110 bar values along the y-axis at value 55…?  Thanks ahead |

Hello,
HPFP from LOBA received and installed on my 2.5TFSI. Loba said me piston size is 12.1mm, so i use these values :
first :
- RQUAHDPK : 36,6mm²
- SKHDPMX : 4,5mm
- VHDP : 368cm3
=> actual pressure rail > requeted
then :
- RQUAHDPK : 36,6mm²
- SKHDPMX : 4,5mm
- VHDP : 348cm3
=> same result, actual pressure rail > requeted
Ori values are :
- RQUAHDPK : 25mm²
- SKHDPMX : 4,5mm
- VHDP : 251cm3
Do I need to reduce SKHDPMX ?
bro, the below are the values of the oem pump present on 2.5t ? could you confirm me please? Ori values are :
- RQUAHDPK : 25mm²
- SKHDPMX : 4,5mm
- VHDP : 251cm3 |

Guys just got VIS STG1 HPFP upgrad iternals for my BWA engine. So after installing new HPFP itenrals i`d like to konw is it my calculation right befor i`m going to reflash ECU. VIS Motosport STG1 HPFP Iternals
RQUAHDPK: 25mm²
SKHDPMX: 5mm
VHDP: 392.5 mm^3
RQUAHDPK= (10/2)^2 = 25mm²
VHDP = 25*3.14*5 = 392.500mm^3

Hi guys!
I'm worried with some HPFP modification I saw last weekend, and I'm asking for some advise from you.
The car is Euro A4 B8 1.8TFSI (Bosch closed style HPFP - not upgradable with different internals).
Two years ago I made for this friend moderated tune for K04-064 and it was working ok on the stock HPFP.
However it seems power is never sufficient, so now the car have proper BIG turbo, and because I mentioned to him fueling will be an issue they decide to put on the car HPFP from 2017 RS3 DAZA engine.
He told me this pump is good for over 700HP, our target is not more than 500, so should be enough.
Good thing is that control signal to HPFP should be the same like his old HPFP - car idles well (beside fuel pressure too high DTC error) - let's say that is fixable.
I start to look for parameters (piston diameter, cylinder volume) of this DAZA HPFP and unfortunately I can't find anything to starts with.
What really bothers me is that 1.8/2.0TSI EA888 gen2 HPFP have cam lobe with 3.5mm lift and I can see this in KLNEHDP in his original file.
However RS3 pump have 4.7mm and it is defined as such in KLNEHDP in every RS3 original file I could find.
It seems driving lobe of those two cars is totally different. Now I'm afraid RS3 HPFP will not make enough pressure with 1.2mm less push when paired with 1.8TSI driving lobe.
Am I right this will not end well paired with capable turbocharger?
Is there a way to use vacuum pump from different car, so we can get bigger stroke, more close to standard 4.7mm of RS3?
