1227808 for all VNs and VPs (auto or manual, V6 or V8 - memcals differ of course but the ECU is the same). The VR manual ECUs (16183082 / 16206305) are also a direct plug in replacement.

Look at the four letter code also on the ECU and/or memcal chip and compare it to this list to see what tune you have:
