K3-VE2 to K3-VE

A very quick question:

Is there possible to fit a K3-VE to my K3-VE2 Sirion with the factory K3-VE2 ECU? It will work? And if it does, it will effect the K3-VE engine positive or negative?

Thanks in advance.

should be straight fit, need to go to dyno to see if the AFR is still correct

You may have a bit less power as the compression ration is less than the ve2. The ecu will still try to aim for 14.7 for if using the stock ECU’s.
