I have a question about setting up LINK at high altitudes.

Hi

I plan to challenge the PikesPeak International HillClimb.
4000m test is not possible in Japan.
I'm worried about the low air pressure at Pikes Peak and the fuel going out of control.

What settings do I need to do in link to climb 4000 meters?
Are there any countermeasures against this?

My link settings are below.

Fuel Equation Mode >> Traditional
Equation Loasd Source >> Load=MAP
Fuel Table Load Axis >> MGP
 
I checked and set the "Equation Load Source" in the manual.
(In order to get Barometric Pressure Correction into the fuel calculation in this mode, the Fuel Table Load Axis should be set to MGP.)
 

thanks.

Yes, the settings you suggest above take care of the general change in air density due to altitude. 

However there is another factor to consider with turbocharged engines - if you want to maintain the same MAP (same power) as altitude increases, then the turbo charger has to work harder due to the increasing pressure ratio (higher boost/MGP is required to maintain the same MAP), this means higher EMAP which of course reduces the engines VE. So you may need a 4D table referencing either EMAP or Altitude/BAP to correct for the restriction that the turbocharger adds at higher altitude.
