Hi Guys,
Been having great luck and results with the Speed Density 3D VE MAP fitted ROMs,
My only concern is the BAROMETRIC FUEL COMPENSATION based on Altitude as I live in an Area that I constantly change altitude from sea level to 2100m mountains..
While datalogging using ECUedit, Barometric Pressure is fixed and doesn't move while climbing, but if I turn off the engine and start it again, then Baro value reads correct at that place;
I think the ecu needs to have another MAP sensor as a Barometric Sensor in order for the algorithm to work, Am I correct ?
I wonder if realtime barometric fuel correction would work in those SD Roms with the Stock ECU ?
Another related one is Turbo Wastegate duty, is there a "table" that allows compensation of WGDC based on Baro ? Because Turbo Boost Drops a lot above 1000m ...

Kindly
Thanks

 

There was discussions about an active barometric measurement from Mr.Fred but there is limited information. You may want to do some more digging around the forums to see if you can find any code or patches for it.

 

I was digging a lot here about this. I didn’t find much info, it appears that patch has never been posted / discussed here.
baro pressure will not change as it is measured when you put ign on and then the number is « locked » in memory.
there is currently no routine which take into account achive baro reading, AFAIK.
