VTEC engagement issue.

Ok so everythign works when I have the P2P plugged in. However when I plug up the S300 VTEC is not engaging.

Its a P06 chipped to P28 for VTEC. Here are the pictures of the board. Is there somethign missing. Is it not chipped for VTEC like its suppsed to be.

Here is a shot of the VTEC tab in SManager. Everything set correctly?

I did lower the kPa down to 85/50, it was at 78.x before hand. havent tested it at this new pressure. Now that I think about it is this value supposed to be negative? Since its N/A?

Disregard the display readouts. I just went out and uploaded the new adjustments. Its still like 95 degrees outside and its after 9PM, wtf!

Here are pics of the board. Not sure if something is supposed to be soldered in those three square 5 pin locations.

That ecu does not have the VTEC components.

That clear ECU cover was made at my shop though..

Ya its a nice cover, got it of ebay.

What components do I need to finish adding VTEC to this ECU?

edit:

Ok I found a video on the socketing, from what I can tell you just need to solder in a transistor into IC14. However I don't know what kind of transistor to get.

Depends on what was already added.. At the very least, it needs IC14

Do you know the part number for the transistor needed.
