Au vct ecu vs hp ecu

[Sox]

Evening kind people,

As some of you AU fans are aware, I'm building an AU XR6 VCT wagon.
So far, the body and interior is done, but I still need to do a head transplant.

The mechanical side is easy enough, and the electrical side also looks easy as it appears I only need to fit one extra wire to the ECU for the VCT solenoid.

So far so good.

Now, my question is this - I want to fit the VCT ECU now, before the VCT head is fitted.
Will this have any negative consequences in regard to ignition timing or fuel mapping due to having a cam which is stationary.

In other words, does a VCT ECU change the ignition timing and fuel map when the cam is advanced/retarded?

Or is it basically the same as a HP ECU, just with the VCT trigger?

I think your on your own Sox, you could try & find out for yourself but for me i would wait till the vct head is fitted just so nothing gets damaged ie: the ecu itself. Your call mate!

cheers, Maka

I can't see how the ECU could be damaged simply by not having the VCT trigger connected.

But I think you're right as in it's a suck it and see thing for the ignition timing and fuel map.

I'm just being conservative Sox, nothing should get damaged but murphy's law may apply here lol!

Fair enough, I know all about Murphy!

In case someone else wants to do this, I have done it, with no adverse affects.

It feels identical to a XR HP ECU.
