I did B20VTEC conversion exactly like it says in http://www.c-speedracing.com/howto/b20vtec
But when I drove the car from 1st-3rd gear all shift at 7000 rmps but the VTEC won't kick in. After few times I tried then the check engine light shows up (code 22: oil pressure switch). Also does it matter the size off the hose I use? Cause before I use a slightly bigger hose,the VTEC won't kick in then I use exactly the same as it says on C-speed,still doesn't work.Both of them shows up code 22. Also I checked my oil pressure switch and it's working fine. Anyone knows what is the problem? Thanks.

Did you trace tha path all the way to the ecu? or just check voltage at the sensor?

I just checked the voltage at the sensor.Yes, I will checked according to the B16 manual. Do you think I get a bad ECU?

Is it possible because I milled the head 0.75mm? And I cleaned the head from debris after milling it, so the debris won't get stuck on oil line later.

I find out that I don't get enough oil pressure to switch on the VTEC. SO, I will take it apart again the engine and see what's going on? Does this happened to any of you guys? Any suggestion?

This maybe a stupid question. Does a VTEC controler can fix my problem?
