HR head swap will require aftermarket ECU or piggy-back ECU as the Nissan 370Z ECU expects to be managing VVEL and HR head swap will delete VVEL.

I am involved in a major CANbus sniff exercise on a Z34 but it is at least 3 weeks away from any sort of conclusion with no guarantee of success just yet.

"If" this works out as expected, there will be an aftermarket ECU option to run a VQ37HR in a Z34 chassis but there will also be some constraints ..... like cruise control will not be a feature, not sure about ESC/VDC and some other similar features.

When I have something definite to post, it will appear in my race engine thread (Search for "VQ40HRGA").
