although a VR tune with lean cruise enabled
This is something I don't understand - Assuming it is a factory fitted feature, if it goes lean at cruise then the cat is not receiving it's favourite exhaust gas composition, so how can the cat work properly?

The cat will work effectively and efficient as there will be less hydrocarbons and carbon monoxide.. At a low load cruise its not uncommon for new cars to run as lean as 17:1

Negatives are you will get a high content of nitrogen oxides in your exhaust and higher exhaust temperature.. Go too lean and you will see pinging..

Positives is more economical car..

sounds like the vehicle anti theft (vats) kicking in stopping it from starting, and running.

need to get the ecu/pcm memcal retuned, guessing you didn't transfer the BCM/keyhead(keyfob) and all the rest of the wiring from the VS into the VN, VS from memory is much the same as the VR loom i used in this but i will have a look through some schematics to double check.

look for "1 = Anti Theft Module Disabled", set/tick to disable

the VSS error's shouldn't be there as it's wired into the loom and directly connected to the pcm, worry about getting it running before chasing other issues...

These chips can take a bit of time to erase fully when theyve been rewritten to a lot of times, so give it a heap of time erasing and then try it. .. They do eventually die though after a lot of erasures/rewrites.. Ive got a couple of dead ones laying around that wont erase or cant be written to any more..
Also I sometimes find that with my gq-4x(now that its a couple of years old and has been used heaps) can get a bad connection between the memcal adaptor pins and the burner socket, I just move the adaptor slightly from side to side in the burner socket, with the clamp slightly shut to put a slight pressure in the pins, and this cleans the contacts in the burner socket enough to get it working correctly again.. The socket must get some slight surface corrosion and this can be enough to stop it from getting a proper connection sometimes..
