B16a Vtec question

[mugencrx04]

I just got my B16a installed. I have had it in for about a week now. When I first got it the vtec kicked in hard and it was loud. Now i cant tell if vtec is engaging. My valves needed adjusting when i got the motor but i diddnt have to money so im waiting. It kinda seems like my valves are ticking louder the more i get on it. Could the valves have something to do with the vtec not engaging?

Check your oil level - if oil pressure is off VTEC won't engage. Your valves are probably loud because there's no oil.

Most Hondas and B16s seem to have especially loud valves.. At least they sound that way to me.

Things that need to be good for your VTEC to work:
The car needs to be up to temp
Oil pressure
No check engine light
Speedo has to work

Try warming your car up for awhile.

Is this true with OBD2 d16y8? Just wondering cuz my friend had his speedo to hydro trans unplugged (dx tranny and ex ecu connector does not match up) and he had a CEL too. There was no tach so I had no clue what rpm it was at in his big 1996 coupe so

Yes, VTEC will not work with the CEL on.

Is that only with OBD 2? Cause my CEL is on but my VTEC still works, I'm runnin non OBD. I have my TPS unplugged due to problems, I know it won't engage if the speedo is unplugged.

To my knowledge, thats with any OBD type, unless VTEC is rigged up... The ECU wont send the signal to the solenoid otherwise... If the engine has a problem, the ECU dosnt wanna overload the engine and just make it worse... Its a safety feature...

I'm not 100% sure about non-OBD but I assume that it is the same. I don't think I'd ever drive my car hard with the CEL on to find out.. I'm certain that on OBD1&2 it doesn't work in that situation.
