Coz I have a gen 3 engine sitting here, I can either
1) Make modification to make the ECU think it's a Gen 2
or
2) Go Gen 3 PowerFC.
Option 1 is my original intention, but option 2 won't hurt neither.
$1k for the ECU and $300 for the commander.
Or you can import one yourself, they're around $1800 for both incl shipping.
