I'm sure it could be made to work, but why bother?
SDS would be cheaper and lots of support. MSnS even cheaper and quite a few people running it. 300ZX system about as cheap as MSnS and no programming issues.
Any of these alternatives will give better driveability over stock ECU, and eliminate dreaded lean condition starting @ ~5k rpm.
With the VPC you're stuck with the lean condition, and poor driveability, plus the $ necessary to pay someone to program the thing. In the end you've got something unique, that no-one else would probably want - and for good reason.
JMHO...
