# Plug In Board Process
|
|
|
|
## Step 1 Research
|
|
|
|
have wiring diagrams in random loose format: pictures, scans, PDF, text.
|
|
|
|
## Step 2 Data Entry
|
|
|
|
have ECU connector pin-out in google spreadsheet form, with explicit function of each pin, often with analysis of multiple vehicles with similar pin-out. [Good example](https://docs.google.com/spreadsheets/d/1H0cZPAJFbpprgSu1Y8BiAYzXbqddvIn-Hhod4QCVQwk)
|
|
|
|
## Step 3 Breakout
|
|
|
|
Breakout board for that connector to reduce risks, also a product by itself!
|
|
|
|
## Step 4 Start of KiCAD
|
|
|
|
Pin-out data entry into KiCAD
|
|
|
|
## Step 5 Adapter
|
|
|
|
Proteus or else adapter for specific vehicle, based on steps 2, 3 and 4. Because cheaper fabrication and less labor intense.
|
|
|
|
## Step 6 Plug In Hellen
|
|
|
|
Full plug in board like Hellen if demand exists. See <https://github.com/rusefi/rusefi/wiki/Standalone-on-Demand>
|
|
|
|
## Step 7 Hellen real vehicle tests
|
|
|
|
We are getting good at these Hellen boards but a board is not done until tested on a real vehicle. A master tech skill set is needed to turn a Hellen into a proven board!
