* FHOKH - minimum altitude factor for cat heating
What is up with this? It isn't a pressure value. In britishturbo's files, it isn't even halved... it's just set to zero. And what about the rest of the FHOs?
FHODSL - SAI?
FHODTEA - Tank ventilation
FHOE - "substitute value for altitude?"
FHOKOB - AC compressor?
IMHO, there is no need to touch FHO* and other F (faktor) constants. Because unit of measurement for F* is usually pressure divided by some other pressure. Let's take FHOKH as example. In FR fho_w is compared with FHOKH. (If fho_w > FHOKH and B_hag then ... do something) fho_w is calculated (roughly) as pu_w/1013 We already divided pu_w by 2 and divided 1013 by 2, so fho_w factor should stay the same after conversion... (1/2)/(1/2) = 1/1  Therefore no need to modify FHOKH and other FHO* constants. |

Have you tried these files yet? It seems like the O2 sensors don't work at all using your 3 BAR file. |

Guys, which map sensors are you running to get 5bar of absolute pressure?  To me it looks like we can run either AEM universal 5bar map sensor or oem 4bar (0 281 006 060)? BTW: what about 0 281 002 420? |

I was thinking about this for a bit...
Did anyone try to cut everything in half and make diagnostic steps x2?
So it will read actual pressure over OBD?
If no one tried yet i'll take emulator and try to make it work.
Than you can run 4 bar MAP sensor and read 4000 mbar over obd without boost cap.

I don't understand the question. What you just listed was a summary of this ENTIRE thread, and the 5120 project in general. |

I have read all pages, so sorry for my ignorance if i have this all working already.
But i thought you read half of actual boost level in log over OBD..

ME7Logger can scale the signals however you want. #!/usr/bin/perl
use strict 'vars';
# use Getopt::Std;
use File::Basename;
foreach my $file (@ARGV) {
open(ECU, '<', $file) || die ("Can't open $file");
while(<ECU>) {
my @line=split(',',$_);
if ($line[5]=~m/{m[Bb]ar}/) {
my $len = length($line[8]);
$line[8]=sprintf("%*s", $len, $line[8]*2);
}
print(join(',',@line));
}
}

The variable is half but the obd2 routines out half too so I fixed that. ME7l uses VAG diag routines not generic OBD2 just a mixup sorry  |

I've run those files, no O2 issues.... |

yes, but i meant that obd gives right actual boost so you don't need to multiply afterwards in the log or in ME7logger.

Do you have a patch I can add to the M-box bins posted in this thread? Thanks! |

Understood. I don't use VCDS for anything except logging adaptation values, but I can see how this would be valuable. I will add the changes to the M-box bins posted in this thread if somebody tells me what to mod Thanks, and sorry for the misunderstanding. |

Ok, i'll try if i can figure it out than.
With diesels i do this all the time, obd protocol is 8bit so 255 steps and you tell steps to be bigger so not max out at 2601 mbar, but make it as high as you want (with lower resolution..)

which amounts to the same thing as the ME7L changes: i believe to get full range you'll have to tell VCDS that it is scaled differently, or you'll max out at 2550 again! |
