Amber, not directly. I tried, but my voltage reader wouldn't work for some reason. So what I did instead is try it on a carto and increased/decreased the voltage. I then went and changed it between VRMS and average mode; sure enough, it fired hotter using the average mode, just like the
reviews said. More importantly, I put in watts mode and it changes just fine. For example, I've figured that my T2s tend to fire better at around 8.5 watts, while my carto tanks tend to perform best around 10 watts. My voltage reader doesn't seem to work on my Zmax either; I wonder it has something to do with that pulsating thing.
