93 accord f22b1 swap questions

[93cb7_JDM]

I just done a f22b1 vtec swap on my 93 cb7. I used the vtec ecu and the car runs perfect but when I go to wire up vtec and I run the wire to the ecu from the solonoid it won't allow vtec to kick in and limits my cars rev to 5k. Could this be because I have to have a pressure switch hooked up to? Someone told me that vtec won't be able to engage because I used my f22a6 external coil distributor but someone else told me that I just have to have the pressure switch hooked up to. When I hook up the solonoid its throws the vtec pressure switch code. Could someone help me figure out how to get my vtec to engage.

You need the VTEC pressure switch to be hooked up. If your ECU is causing your check engine light to be on, then it will usually not allow VTEC to engage.

So does my f22b1 having a f22a6 distributor with an external coil instead of a f22b1 distributor that comes with an internal affect anything at all? I understand that my cel being on could cause vtec not to engage but can a cel cause my car to not rev over 5k?

It's possible. The CEL essentially means the ECU is in "limp mode".

I'm not sure about the distributor. This isn't a very common swap, since the F22B1 is more of a downgrade than anything else.

Im running an external on my f22b1 set up.I have no cel on vtec sol and pressure switch have to be hooked up for VTAAAAKKKKK to work.You are Not really gonna tell its there as it kick in at 2200-3200rpms.

I know wiring on the b1 is different to the ecu there are a few pins that you have to swap around and wire vtec but there is a few threads on here regarding this swap

[SOHC-FTW]

I just did a little researching and found out infact you can use any distributor from our cb chassis.You just got to pin the ecu for vtec and run them correctly.If you haven't done this do so.If you have make sure you didn't cross them up or vtec sol or pressure switch could be bad.

Well if I have the vtec solo unhooked it throws the solo code but the car drives fine just no vtec. But when I wire it up to the ecu it throws the pressure switch code and won't allow me to rev over 5k. I'm pretty sure the dizzy has nothing to do with it, that was just curiosity because I've heard that before but ill wire up the pressure switch and see if it fixes it. Thanks a lot for all the info.

No problem man.Also vtec is activated by oil pressure if the switch isnt pined, and hooked up you will throw a cel and have no vtec and could very well send you into limp mode aswell.
