Recently installed a field vtec controller CORRECTLY. Have speed hooked up, rpm signal, vtec engagement, power, ground, map, all works and no check engine light, but no vtm connection (green/white wire) when vtm is connected car runs crappy and my engine throws code 22 - vtec oil pressure signal, but car runs fine w/o vtm connected (vtm to ecu side, engine side blocked off) I leave the stock vtm wires connected (d6 on p13 ecu) I've checked my wiring a hundred friggin times. When driving w/o sfc on car runs fine. When sfc is on, here's the trick- as long as I don't float into vtec (normally needs oil pressure to activate lift) the check engine light won't come on. If I linger @ 5000rpm's or whatever vtec is set at THE FIELD UNIT RELIES STRICTLY ON RPM SIGNAL TO ACTIVATE VTEC, it bounces in and out of lift and I get a check engine light w/ 3,12,21,and 22. Those are map, vtec pressure, vtec solenoid, and EGR codes according to hondata. I think the unit itself is junk, as I am becoming a mechanic working on this damn thing. Can someone w/ some knowledge please help me out. thanks

I know on the Apexi V-AFC, you do not connect the VTM wire at all... I'm not really familiar with the Field unit, though.

Try this page on good old VTEC.net to doublecheck your wiring:

From that page, it looks like you DO hook up the VTM on the Field. Hmmmm:

yeah, that's the 5th gen obdII schematic. My p13 doesn't like it when you disconect the stock vtm lines. I think the unit itself is supposed to trick the ecu, but it's defective, cause it throws the vtec pressure light when hooked up correctly.
