I'll have to check when I get home, but I don't remember that being the case.

Im 99.9% sure julex is right, altough it looks a bit different in my binary as all my dynamic q0/q1/q2 are KF's, they all have the lde axis which I have documentend and scaled 50%. But, the static q0/q1 I have indeed overlooked and should be increased by 100% as the input is halfed with this hack  |

My reading of the FR (and the Q0/Q1/Q2) tables tells me that they all need to be scaled - for maps with lde, plsol, etc as input, those axis, for scalars their values have to be scaled (since they directly multiply lde).

Updated the .txt and uploaded, also included the variances in 2.7tt PID components |

Glad to see you guys making further progress on this!
I've been super busy lately and haven't had a chance to post on here... Looking forward to getting my 3,0 build done so I can carry on working on this!
As far as sensor calibration the way I dialed in my slopes was as follows:
Stock MAP Sensor + Stock Code: Record MAP Sensor pressure in VagCom with Engine off
Flash
Stock MAP Sensor + 5120 Code: Confirm MAP Sensor pressure in VagCom
Flash
400kpa MAP Sensor + 5120 Code: Record MAP Sensor pressure in VagCom (Calculated values for MAP sensor)
Scale hpa/v as needed to get MAP reading ambient correctly
Flash
Check MAP Sensor pressure in VagCom - Do a happy dance

Small setback... while calibrating my KFLDRL @ 60 WGDC, my TBB popped off the throttle body @ 34psi of pressure and took out my shiny new 4bar MAP sensor... The neck cleanly sheared off the main sensor body since I had it on a bracket...
Note to everyone: Don't use factory bracket with high boost application and aftermarket bi-pipes without mounting tabs that fasten them to TB covers...

Damn that really sucks... I'm glad with the single setup I won't have to worry about that given I use a pipe with a welded on flange. If you want I can send you my ghetto 4 bar sensor to use while you wait for a new one, I was going to just get a new one anyway. PM me your addy if you want it. |

Thanks for offer but no rush. Even though it ripped itself out, I can move it around to touch TBB and therefore not have gaping hole in there. So long I don't boost the engine (it goers rich), it works fine without any codes. I'll have a look at it tonight, I have a few old 2.5bar ones, I will see about transplanting internals to old sensor body. It will also give me a good look at what's inside |

i know that you guys already accepted this, but I took a look at lditv_w and Julex is right.
I haven't done this part of LDRPID yet in my 5120 travels, but I'm going to just finish the function since I'm already in there.
Edit: Since leaving home, I decided that I should've said my initial interpretation is that Julex is correct. I want to take another look when I get home before confirming 100%.

100% confirmed Julex is correct.
lditv_w in my 5120 file with lde of 10mbar (original ME7L scale) and ldrki_w of 0.6 is identical to original M box with lde of 20mbar and ldrki_w of 0.3.
Sorry, I just like to be thorough.

Cool, one more kink straightened out then. Once I have new sensor in, I will continue to tune the car and report back.

another question that do already relate to quite slighty tunes: did anyone consider to alter the system constant sy_mdnorm (MDI) in the code to a higher value?

Im currently going through all this for a Volvo ME7.
I have a short note on DLDR. I think lde has half values with this mod and then you should alter DLUL and EDLDRP also.
Same with ELDOB in LDOB.
BR, Daniel

Guys, I don't know if you already seen this but KFLDHBN maxes out at ~3 BAR of boost and it will limit LDRXN/LDRXNZK. Have you found a way to overcome this?

I dont think most people will have problems with that, if one wishes to run 3bar+ then a simple load underscale would do the trick |
