High Altitude Driving. Tweaks ?


Recommended Posts

We are going across mountain pass(s) at well over 5000 meters. What tweaks should I be prepared to do.

More specifically how exactly do i do them. I'm obviously thinking fuel injection pump and turning down fuel.

Thanks

Neill

As much as it annoys people....

are you sure it can compensate for that altitude ? I'm sure someone told me to turn it down but cannot remember who to blame for me having to quiz you.

( I'm not meaning to annoy you or the people that will witness the black plume of unburnt diesel coming into Chili / Puru. I just don't want to end up not moving at some point due to not knowing something I should know. If you know what I mean )

I drove a virtually new Puma from Santiago to La Paz a few years ago. I think the maximum elevation we went through would have been around 4,200 metres. There was a noticable drop of in power as you would expect from the reduced amount of oxygen available but on the whole driveable as long as I wasn't thinking about the possible harmful effects of the unburnt fuel. Clouds of black smoke on start up from cold but not too bad when hot.

As far as 5,000 metres is concerned I think you might be approaching the limit. I vaguely remember reading somewhere that the normal injection set up will compensate up to 3,000 metres.

Cheers,

Del
