ECU Bench Flashing
What you need
- 12v+ DC power supply
- Flashing cable (Ebay, Galleto, etc)
- Small gator clips
- Small gauge connectors
- ECU & OBD harness (optional, but very handy)
Set up your 12v+ DC power source. Make sure you have constant and stable power! The PS-3KX is nice and inexpensive. An ATX (computer) power supply (12v) is also a popular choice.
The wiring is simple. Power the ECU and power the cable. Then connect one K-line wire between the two.
