SD Tuning and altitude

[bmax]

I am still logging/learning in SD.

I was wondering, if I log at sea level and then in a few weeks I go up to a buddies place in the mountains that's 1200' higher elevation and do more logs,

Will this change my O2 readings on the wideband enough to make a difference in my tune?

Thanks in advance,

Brad

Theoretically if your SD/VE Tune is spot on, density changes from altitude are easily covered by the 'VE air mass calculation'. Your MAP sensor acts as a barometer and will change (lower) as your elevation increases, and the change in density will be accounted for.

If your tune is good, no problem.

Thanks for your input, again.
