Tuning and elevation

[mainline]

I am originaly from upstate NY. I plan on taking my evo there in june/july for a month. If i get my car tuned on 91 pump in colorado, will the ECU and MAP senser adjust for the elevation change acrossed country and in NY (close to sea level)?

You will have to re-caibrate your JDM MAP sensor if that's what you're using to correspond with your elevation. (This is ONLY for logging purposes). Nothing to do with the ECUFLash/tune portion of the map sensor.

If I recall correctly, NY has 93 octane?? If so, you'll be good on the tune but may run just a tad rich...

Cheers-
