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 MUST USE 5151's OR EQUIVALENT on this board revision. 5050s will throw VTS code.
- D11 - Clamping Diode
This is an evolution of the "1720" board design. Things are simpler, as is evidenced by the conversion having fewer components than the 02 D01720-1500 conversion.
Automatic P06 ECUs have SK-5151 high side switches, just in different spots. Desolder them both. Use one for conversion, and save the other one. The A143 transistor @Q101 can be taken from Q28 or Q27.
(Note: I've noticed that IPT bd. 11F0-1500 automatic does not utilize Q27 or Q28, you must use transistors from some other source.)
