I think its defiantly down to the ecu code... maybe someone has a spare ecu who's running a 976 and can swap it out to confirm or vise versa...
Thing is, unplugging MAF on a good stage 2 wouldn't have confirmed it, because the built-in MAF values are waaayyyy off those needed to run a good stage 2 fuelling.
You'd be down at just under stage 1 fuellings.
Changing something so fundamentally wouldn't allow you to confirm it in this case imo as the difference would be so huge!
ELM 327's can be had for about £15 these days off eBay, nice all in one cables too, and any half decent OBD scanning software can look at the basic sensors and you'll be able to confirm a lot more about the operation of your car/fault finding with them
