I'm converting my OBD1 P06 02D011F0-1500 board to VTEC, and I'm using these instructions from the library:


to convert non-vtec "11F0" boards from non-vtec to vtec, add:

In top left quadrant:

C60 - 1uF, 35v electrolytic (tantalum?) capacitor
J10 - 0 Ohm jumper wire
Q101 - A143 PNP switching transistor
R201 - 10K resistor (Brown-Black-Orange-Gold)
IC14 - 515 XHigh Side Switch
D11 - Clamping Diode


I could find all of the location except R201. I found R102, R202, and R203, but no 201. Was 201 a misprint or am I blind. I've been looking at this thing for an hour. I even pulled my p28 out of my beater and tried to find it on there, w/o any luck. Help is much appreciated.

I feel like such a tard. I just found it, but guess what, it allready has a resistor installed. Allready Brown-Black-Orange-Gold also. WTF? So do I just skip it, and do the other mods, or is something wrong?

dunno why 201 is listed. I've converted 6 ECUs and every single one of them have already had it. I spend a while trying to find it also. Your looking for an empty spot and there isn't one :twisted:

Good to know I'm not the first one. SO I guess it will work then. Yippie. It looks as if some of the components can be found on my old OBD0 DX ecu. is it possible to just desolder those and reuse them on the p06 vtec conversion? It looks like everything is there except for IC14 - 515 XHigh Side Switch? Has anyone tried reusing any components like that?
