Hondata and high altitude / high elevation
Does anyone have experience at high altitude (elevation) with the standard Hondata flash?
Given that's it's leaning out the mixture a little, I would expect it's even better for cars at high altitude but, from what little I actually know of performance tuning, I think that could be negated by the turbo...?
Any other thoughts on doing the Hondata at high altitudes? Can it be further tweaked for driving at 5,000 feet and above? Any other recommendations for high altitude?

It leans it out as far as what the commanded AFR is vs. stock, and elevation shouldn't matter as long as your MAF is working. Car will adjust fuel as needed to meet the commanded AFR. Generally speaking elevation doesn't affect turbo cars nearly as much as n/a.

I live in ABQ, NM, at an average altitude of 5000-5600ft. I have:
- Hondata (reflash for over +3yrs),
- ETS intercooler (for only several months),
- K/N drop-in filter, and
- Hondata heatshield gasket.
I was in SoCal for vacation in the RDX and I did feel a boost in power at sea level compared to ABQ. The RDX pulled a little harder and it felt like an additional 8-10 hp with the old butt dyno. I also traveled between 7,000-11,000 feet in Colorado and New Mexico on vacation and the turbo and hondata really work very well with minimum loss of power. I had zero problems maintaining my speed or accelerating quickly to passing speed even when traveling on I-70 on Eisenhower pass at 11,000 feet.
I think a supercharger and turbos have an advantage at higher altitudes because they can just spool up more air pressure and add more fuel to maintain HP compared to naturally aspirated engine that would give out at the same altitudes. I would recommend Hondata if you live +4500ft elevation to get back any HP because of the elevation.
