Barometric correction will help your fueling when going dramatically below/above sea level.
Hardware needed:
Hope it is still on.
It is the same sensor as the DIYPNP MAP sensor. (now you will have two of them :))
Installation:
Mount the second sensor on top of the first, solder the legs together as shown in the picture, solder the left most leg to the baro hole on the PCB.
k ?
Setup:
Change this two as shown in the picture.
Tune:
This is untuned of curse, the reason is that I use the EGO correction and I usually drive at sea level...
You can tune the curve to add or decrease fuel according to barometric pressure.
Have fun :)
