Product description
2-wire idle valve PWM control mod kit
Product details
Kit contains:
- TIP122 transistor
- Mica insulator
- 1N4001 diode
- Heat sink grease
All needed parts to control 2-wire PWM idle valve. Can be used with both V2.2 and V3.0 PCB.
V3.0 Installation:
Don't install Q4 transistor or remove it. TIP122 in kit can be installed in place of Q16, that is usually left empty. Or you can bolt it into case. Important is to connect TIP122 into heat dispatching surface using Mica insulator and heat sink grease.
Also don't install Q20 and D8. Leave R39 out too and jumper it with resistor or diode leg or similar
1N4001 diode should be installed between right side hole of D8 and banded end on S12 hole. S12 is found bit above processor. That diode is for flyback purposes
+12V for valve should be taken from fuel pump relay.

V2.2 installation:
Replace transistor Q5 with TIP 122. Best way is to attach TIP 122 to casing with Mica insulator and heat sink grease.
1N4001 diode should be installed between idle valve wires. Banded end on +12V and non-banded end at pulsed grounding wire that goes to MegaSquirt. That diode is for flyback purposes
+12V for valve should be taken from fuel pump relay.
