I've decided it's worth it to me to take the extra time and swap the
digifant ecu/harness in when I put the 2.1 in.  The only thing that'll stay
1.9 is the cooling system.  The temp II sensor on the 2.1 is in a different
spot along with being a different style sensor.  Is the 1.9 temp II sensor
compatible with the digifant, just a matter of extending the wires to reach
the stock 1.9 location?  The coolant gauge sender is a two wire on the 2.1
and only one on the 1.9, so I feel like I'll have to work something out
there, too.  I'm excited to get started, just waiting for the tax refund to
get started!
