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.

 

Do you have a knock sensor wired up?

 

Yes,I have my knock sensor wired up.

 

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?
