I will back down a little on this. I was using an older version of ecuflash on a Mac. I just checked it out for the first time in a long time and using keyboard shortcuts it's not really bad at all. Didn't look into it but if I could switch from Bar to Psi I'd use it instead of RR. And yes, now left click works too. Didn't prior for some reason. It's still not the most user friendly program.
