Vy Engine Downgrade PCM+BCM

[eXcon]

We definatley have a problem.
2003 vy supercharged engine blown.

Went with a std vt ecotech with vy loom.
VT chip in supercharged comp runs fine for 10 secs then cuts out - presuming immobiliser - vats issue with vt memcal? Does that need to be linked?

The stock vy s/charged bcm is labelled MID.
i have sourced a vy calais kit including pcm bcm and keyheads.

Is this a suitable alternative to linking the vt memcal?
Car runs like crap with vy memcal and perfect with vt but cuts out.
Soz bout the post im posting from iphone - its torture

Please help me understand all possible oprions as i have been stranded for weeks
Thanks !

So long as the price for the vy calais pcm, bcm and keyheads you've sourced is reasonable, this is the method id take. Everything will be a straight 'plug and play' swap with no mucking around (have done it this way a few times myself). Another alternative would be to have the VATS removed from your vt memcal.

VT and VY use different serial data and aren't compatible. Use the VY ECU/ BCM or get the memcal modified to suit your N/A engine.

was speaking to a guy the other day who had a vx with a vt supercharged motor and he said all he had to do was relink the bcm to the pcm.
