Well, the Elise AC can do whatever you tell it to, but yes, it will ice up. I mean, I can make it produce any temp air I want, why it freezes up when other cars systems don't is a bit of a mystery. The TXV 'should' stop it.
With the stock old style thermostat I get air temps in the mid 40's with a cabin temp of low 70's and outside temps in the 90's. I have significantly improved airflow, but if I try to lower the air temp it ices, when really, it shouldn't.
I'm just wondering if the newer thermostat raises the air temp[which I would consider worthless] or is jsut more accurate or something
If I had nothign better to do I would expirement with different TXVs, because the TXV should really stop it from icing.
