BT's location is correct.

This is MED9 code but in C167 asm.
Any ideas on how this equates to a division? It breaks my head.

I am trying to figure out why MSDK_W (flow over throttle plate) is roughly 1/2 of actual maf flow.
I followed ME7.1 bible and it appears that BGMSZS. bgmszs-lad function, fpvdkds_w * fkmsdk_w calculation is at fault here since the fpvdkds_w is 1/2 scale and is used directly in further multiplication with msdkue_w to give msdk_w... KLAF table output multiplier shouldn't affect this much although input to it is also 1/2 of what it should be.
Anybody has any idea for quick fix to this?

Hey guys,
I collected some data for both my 5 bar AEM "brass" MAP sensor and my AEM 5 bar "Stainless steel" pressure sensor. The brass sensor is being logged via ME7Logger with a DSLGARD = 646 and a DSLOFS = -323 per my calculations. The stainless steel sensor was being logged via my Zeitronix datalogger (both sensors logged during the same run at the same time).
You can see that the sensors track each other quite nicely (my offset is off about 2psi with my DSLOFS calc) and the brass sensor is a little bit noiser (too be expected).
EDIT: Correction, looks like I had a typo and my offset was actually -330 instead of what it should have been (-323). I will correct this and see if this corrects my offset error.
EDIT2: So it turns out I was wrong here. I replaced the brass sensor with the SS version and my boost curves now fall right on top of one another. DO NOT USE THE BRASS SENSOR IF YOU WANT ACCURATE READINGS!

I believe the reason for the 2 psi offset is due to the brass sensor being about 2 feet away from the throttle body where as the SS sensor is reading off my intake manifold.

They should read the same if placed in the same location, if one is in manifold and the other somewhere else, then it is natural to have some discrepancy due to pressure losses etc. |

I have installed map sensor from diesel and it works perfect. But now I would like to increase boost to 1.7 bar and I think I changed everything (pvdk_w etc) into my file, but idle is unstable and the engine doesnt work correctly (reduced power etc). Its R-box ME7.1.1 and its a little differ from M-box ME7.1
Please help if you know how to make it work.
I would like to install garrett 28 in near future and without this hack its senseless as you understand.

It sounds like you may have missed one or more of the 1013 mbar constants. I missed one at first and experienced the same thing you are. When you say ME7.1.1 R-box, do you mean for the 2.7T (4Z7907551R)? If so, here's the locations for the 1013 constants I changed & I've got the 5120 hack running w/ no problems for quite a while now. Also double/triple check that you didn't miss any other table or axis on the list in this thread. 0x6D8EC 0x6D8F2 0x6E276 0x6E3D8 0x6E400 0x6F22C 0x6F27A 0x6F308 0x6F408 0x6F96C 0x712A4 Use at your own risk & be cautious when doing any pulls/logging until you're sure everything is working right... edit: Btw, I don't have winOLS so I didn't look at your file before posting |

If you would be willing to post your stock file, with just the scaling that would be a great addition to the thread  |

I've been meaning to put a stock 5120 file together to put up here but just haven't gotten around to it. |

Ive just tested it and idle idle is ok, AFR is ok also, but
requested boost = 1250 mbar (2500 mbar without 5120)
actual boost = 770 mbar (1540 mbar)
I think I missied some PID axes or smth like that. And I cant find DPVLMS in ME7.1.1

Those are logged values? Did you adjust the log definition files? |

Its ok now (thanx to erroob0977), I missed some axes. I'm going to test it for some days but looks like everything is ok now.

Not having fun.
