So far, what I'm noticing here is that those having the biggest problems with the Evic are new to TC/TP. I'm a relative newb as well, as I only have one other device that pretends to TP. Plus, those working with the Mega coils and some with the Ni OCC.
I don't think these devices are really built for MTL hitters. I think TP really needs the airflow. I get what one dude is saying about the first registered temperature being high and making it hard for MTL. I don't have experience with yihi or dna40 chips, so me comparing it to those is unfair.
But let's think about TP...where is the temp sensor in any of these devices? There isn't one. Anything that measures temperature has to have a sensor, so all any of these chips do is guesstimate through algorithms. Best they could do is take temp off the legs, which wouldn't match the coil. So, it's key to understand that nothing is perfect, yihi and dna40 have mixed reviews as well.
What I do know, is that I get even temped draws that is regulated by increasing and decreasing wattage with the help of air flow.
I'm not judging anyone...I just think folks need to take the time to understand who the device is for and what the key components to TC/TP are. The good news is that it also does VW, so it's not a total waste for those that can't TP on it.
