Do you have more info or a schematic for this? Sounds like a great mod!Unicat supplied me with an incredibly simple altitude adjustment for my Thermo Top C. 2 T fittings and a finger controlled needle valve. A “short circuit” between fuel supply and return. Open 1 revolution for each 1000m above 2000m.
Altitude is not an issue for the vast majority of these units. The high altitude visiting overland vehicle is a tiny percentage of the market.Some wiz with an arduino needs to make an open loop map with a fuel injector and user inputted altitude for one of these or a closed loop with an O2 sensor or MAP sensor. With how finicky these things are and the price for the original non-Chinese knockoff versions I am surprised they don't come this way from OEM's.
All pending when and where you bought it, the planar already came with a build in altitude compensator.We have a Planar 2kW diesel air heater, and I don't know at what altitude I have used at the highest. But 9000ft is nothing special.
I think I probably used it a few times above 10000ft.
I believe it does not come with height adjustment and it works fine.
