The catsim doesn't work for EWG. My boy and I sat around my car with a multimeter measuring input voltage with cats on, cats off, and cats off + sim.
From what we deduced, the catsim could work if the circuit is modified to output the correct voltage. With the Catsim, a voltage of 1.5 is fed to the DME, which does not allow the heater to engage. The car never goes into readiness, and the CEL is engaged after a few drive cycle.
With the cats on, a voltage of roughly .7-.8 is fed into the DME, causing the heater to come on.
We think lowering the output voltage from the Catsim (to a value around .7v) could make it work. Got my pass and sticker with my cat. Gonna solder the circuit and test when I put my DP back in.
I'll keep y'all posted.
