I set my V-AFC to engage the big cam at 5500 on my 98 Civic EX, I set the monitor so I would be able to see the VTi and VTo, yet they always read "off" at all times and RPM's. For those who don't know, VTo and VTi are the VTEC input from the ECU and VTEC output from the V-AFC also monitoring when there's a VTEC signal, but evidently I appear to be getting none. I appear to have everything set correctly, i've got the L-->H @5500rpm and H-->L @5200rpm, yet like I said when I monitor the sensors, I alway get an "OFF". Any idea's?

 

check and double check your wiring

 

Sounds like the VTEC IN wire is disconnected from the VAFC

 

Well I double checked them before I put everything away so I wouldn't have to go through the jungle of wires all over again, but none the less I'll make sure to check the VTEC wire again. Just seems funny that if it wasn't connected, I should be getting a CEL when the ECU see's no VTEC yet the ECU is fine.. go figure?
