Dyno/Tuning in Auckland?

[jonnyk5614]

Sounds like a step in the wrong direction to be honest

Ordinarily, yes, but dailying it around Auckland this past week....
Now the sun is back I'll load the old map back in

Remember the US has different atmospheric conditions to here, US setups are often way off.

Could you elaborate a wee bit on this?

Dyno tuner here I spoke to said that many setups from the US dont work here. They are often to rich. He has to lean them off.

I believe something along the lines of the air, elevation (height above sea level) and their fuel types change the adjustments they make on the power commander maps - meaning that what may be 'perfect' there will not perform the same here.

Interesting, I'll talk to my guys and see what they say. I find with this stuff getting an answer from heaps of experienced guys seems to work the best. I'll let you know what they say.

I hear ya about elevation, Colorado is +1000m, which implies that there's 10% less air. Interesting that Power Commander doesn't have barometric pressure correction.

Aside from elevation, how else do you think air differs in the USA? And what differences in fuel types need to be accounted for?

Don't know an awful lot about it except that in the US 85 is quite common whereas we only go to 91 (in most cases) in NZ. Also pretty sure they have different additives in their fuel?

I think the gist of it is that while each of the components that change a fuel map may only be small, all together they add up and can result in a different map per region.

I believe they use a different fuel standard to us, we use Ron I think it is. But Im no expert on this so will defer to those that no better.

US often has MON, some places use (MON+RON)/2 and rarely RON.

Yay when you're trying to figure out what's premium for your European bike

My Gixxer has barometric pressure correction in the stock setup though.
Power Commander is only adjusting the stock map up or down. Presumably, the barometric differences are not completely lost by using PC.

The US measure their gas differently. 85 could be either MON or (R+M)/2. 85MON is about 95Ron. 85 (R+M)/2 is about 93RON.
