hks EVC EZ& EVC IV

[jdmawd]

anyone using either of these, and if so what are the major differences in the two?

The EVC EZ has no fuzzy logic and doesn't require any training or teaching to make it work correctly.

The EVC EZ's seem to be used pretty frequently on cars running high psi (20+) with great success.

I believe the evc ez is just like the greddy profec b as in features. I have the evc 4 and like it alot. The evc 4 is more $ but in my opinion its worth it. It has fuzzy logic(self learning boost curve), low/high setting, boost warning, scramble boost(pre-set additional boost for pre-set amount of time), and you can calibrate it easier than others. Just my $02.
