I just installed the VAFC in an '01 gsr. There are two parameters you can monitor-VTi & VTo. VTi= ECU vtec solonoid output. VTo= VAFC vtec solonoid output. My question is--when monitoring these, when is vtec actually engaging? VTi doesn't change as I adjust the crossover point so i'm guessing it's the VTo.
Thanks all!!

 

monitor VTo to see when it engages.

 

Thanks dLo!
VTo is reflecting the changes I make but I'm not sure if it's telling me that just what the unit is set at or if that's when it is actually engaging.

 

vto will tell you you when vtec engages(where you set it at). vti lights up when the ecu says vtec should be on(so on a gsr it'll light up at 4400)

 

That's what I thought, just wanted to be sure everything was working properly.
Thanks guys!!
