Car Forum / Volkswagen / Water Cooled Volkswagen Cars / May 2004altitude
About five years ago I drove my '89 16v Jetta through Colorado into Utah (from Virginia) with a Mad River canoe on the Yakima roof rack. The engine was not happy going up up up. I remember that I dropped below 60mph a few times. Now I have the v6 Jetta. I suppose the 1.8 turbos have no problem at 10K feet, but I wonder how the v6 would handle it. Does the 'chip' controller do any sensing of altitude for changing the fuel air mixtures in my 2003 GLI? How smart is the chip? Sam Most VWs now use MAF sensors, so they measure the actual mass of air entering the engine. Mixture should not be a problem, but you will get less air, and thus less power at altitude. > About five years ago I drove my '89 16v Jetta through Colorado into > Utah (from Virginia) with a Mad River canoe on the Yakima roof rack.

I can report that the 1.8T charges eagerly up the tallest mountain without hesitation. I know I've had it to 8,000 feet, and I think we saw 10K in Arizona last year around the continental divide. Texas Parts Guy Don't worry, be happy... because the ECU has an internal MAP sensor which compensates for elevation changes. If you got a Ross-tech vag I can tell you where to look for the value. > About five years ago I drove my '89 16v Jetta through Colorado into > Utah (from Virginia) with a Mad River canoe on the Yakima roof rack.

I notice there are a few brands with a range of prices, shareware vs full versions of the software, wireless, and other differences, too. Does Ross-tech set the standard? Any comparisons appreciated.

Any comparisons appreciated. Well, it seems to me that, whenever I see a reference to such a device here on ramvw, it's almost always the Ross-Tech stuff. I just got my HEX-COM, and I haven't done much 'cept set my Tiptronic to "sport mode", but it certainly seems like there's a lot of stuff you could do with it. -- Mike Smith Ross-Tech is about as close to what I use in the shop with VW factory 5051 & 5052. > I looked up some information about vag-com.
