'To travel hopefully is a better thing than to arrive.' Robert Louis Stevensonīuilding a bus for travel in Europe (euroBus) '87 Westy w/ 2002 Subaru EJ25 and Peloquin TBD My hope is that this topic will help others in need down the road. He is able to program directly from this program. I am going to ask Hans to chime in here as he has been recently using the diagnostic program and can see any changes. He said that running it lean at sea level will also help to keep the combustion chamber clean.' The tech said you can change it back when at sea level, but also said it was unnecessary, as the reduced fuel will not cause damage at sea level, just a lower heat output by 100-200 BTU/ hour at the maximum setting.

Now the fuel pump should be set to deliver less fuel, thereby creating a better combustion mixture for high altitude and less oxygen. It will keep your combustion chamber from coking up at low oxygen/high altitude levels and will also make for easier starting at high altitudes.Īccording to Webasto tech support here is the procedure:Īt the bottom of the heater there is a pigtail of 2 wires, one brown and one green, that they use for programming the system.ģ: After a few moments, the LED on the heater control knob will begin to flash.Ĥ: Turn the heater control knob to 9:00 (or even 8:00 if you are at very high altitude)ĥ: Keep the heater running with the control knob set to 9:00 for 3 minutes.Ħ: While the heater is running, remove the brown wire from ground. It involves reducing the fuel supply as well, but does not need any other parts. The Air Top 2000 ST can be manually adjusted for high altitude by the end user. 'OK Folks, just got off of the phone with Webasto tech support. Here is a post on the adjustment using the rheostat that I grabbed off an older topic.Īccording to this post, here are the instructions for manually adjusting the Webasto ST2000 for high altitude. But you are supposed to be able to lean out the fuel delivery to allow it to work up to 10,000 feet. The unit is able to go up to 5000 feet stock. I have the Air Top 2000 STC from the Russian site.
