Carb icing LVar?

[ft]

Hello,
I'm trying to read out the degree of carburator icing but have no luck finding a suitable LVar? I'm guessing there isn't one, but I thought I'd throw the question in here anyway.

Eng1_CarbIce_Factor - stays at zero.
Eng1_CarburetorTemperature - stays at zero.
Eng1_CarbHeat - gives the carb heat position (d'oh).
IcingCondition - Stays at zero.
Eng1_CarbAirTemp - gives the carb air temp, affected by carb heat.
There's also AsnAmbientIcing as I'm running ASN, but that one stays at zero as well.

Cheers,
/Fred

There's nothing obvious which reports the extent of carb icing is there Fred. Maybe it's calculated dynamically based on weather conditions read from the sim (temp, visibility and precipitation) along with the existing power setting and level of carb heat applied; then directly written to an L:Var such as "L:Engine1PowerLevel" or similar.
