FastECU

Is there any instructions other then the picture? Do I need to provide the ecu with a bench connection for 12v, etc? is the arduino nano pin out the same for FastECU vs Arduino IDE? Thanks

can mc68hc16bdm be used to unbrick a 04-05 wrx ecu via bdm? It says 02-03 usdm, but since its the same motorola cpu I thought maybe it works?
