I have a JDM SiR II B16 in my 93 dx hatch.

I have everything wired up for the v-afc correctly(been over many times).
Except The "VTM" wire (whatever the hell that is)......According
to the Apexi wiring diagram the VTM wire is where the Vtec oil pressure
switch is. I have the Oil pressure wire (D6) wired correctly b/c it ran fine
with no CEL's before the v-afc install. THe apexi manual shows the vtec
oil pressure at D17.

Now, I spliced the VTM wire into the oil pressure wire and left one end of the
oil pressure wire un-connected. Should I just solder the VTM wire directly into
the oil pressure wire?

It bogs like crazy when vtec hits, and hardly wants to pull to redline with no check engine light. Now here's the funny part. When it throws a cel, it pulls hard again and feels fine (but has the check engine light)......WTF!!!!

How should I wire the VTM wire and oil pressure switch????? Somebody here
must know. Please help.

I know it's confusing but try to follow, please.

 

did you use the updated diagram on apexi 's website? I don't remember it being so confusing when I did that.

 

I looked at the updated pinouts on their site, and it still shows the VTM wire in
the same location as the vtec oil pressure.

Maybe I'll just try wiring it directly with no loose ends into the oil pressure.

Any other suggestions?

 

it's a blue wire...should not be the same position...are you sure you are counting the pins correctly

 

Guaranteed. It shows D4 for the VTC wire. Every site (c-speed, hybrid, Hondata)
show the oil pressure in D4 also. On the Apexi site it shows the oil pressure
at D17. It worked fine, with no codes b4 the v-afc install.

I'll mess with it after work.
