Need your Input on this HONDATA.

I wanted to know if it you can tell me if it was possible to possible to Use an 06 TSX ECM in a 05 TSX (M/T or A/T) without the risk of damaging the engine in doing so? I know that there is a small change with the engine design and the valvetrain components which increased H/P + Tq. And i'm sure that the 06 TSX ECM software may have been changed a little also. But my question is if an 06 ECM was used in and 05 TSX model, would there be any mechanical damage/failure issues, or Proper engine operation concerns. What kind of issues would result from it if any?
The other question is regarding the little difference made to the ECM. I Noticed that the 06 TSX now use 2 ECT sensor which resulted in Adding additiontional wires for the New Secondary ECT sensor . The new sensor wire is routed to ECM/PCM Connector E - Terminal 1 which is not used on previous Models. Other than that it seems like everything else is identical and should plug right in.
Is there a huge difference between the 2 programs with the reflash..?

Well let me know ASAP if possible. I greatly appreciate it.

We do not recommend swapping the ECUs.
