Hey,
I am looking some information about using internal MAP as the BARO sensor and its benefits or problems…
I have for some reason turned on the Baro setting in Map,Baro parameters to Use interman MAP as BARO and also in fuelling general enable baro correction. I dont remember why but I think it was when I was trying to solve lean issue when pressing gas pedal fast.
So what is the benefit of using this option in the first place and is there a down sides on using them?
My car is audi S4 v6 biturbo and im using Emu Black v3 version 3.047 and the newest firmare.
So one problem I have noticed that when I have the baro settings like this
Is that the boost shown in the graph shows 50kpa/g lower than it is comapired to map reading like this. Is there any other down sides with using these baro setting than this 50 kpg/a offset?
The fun part is that if I turn off these baro sensor settings, the offset is correct. but then I will have a problem where the fuel pressure correlation goes up to 10-12 and I got 20kw less power in dyno.
I have now made the VE table and Ignition table with the baro settings on because it was noticed I had it on after tuning for a while.
So is there anything I could to to get rid of the baro settings and still get the corrrect fuel pressure correlation and power, or do I now have to live with the offset. and other issues that the baro settings are causing?
here is my map and testing log with and without the baro settings and 2 dyno runs where one has the baro enabled and one disabled.
(edit) these dyno runs 23 and 24 made around same power. but run 25-26 after them made 20kw less, with same settings. the fuel pressure Correlation however can be seen bethween run 23 and 24.
