Yeah, in a nutshell you have to flip the calibration backwards for VNT rather than wastegate - plus the response is completely different.
You can do MAF deletes on VAG stuff and use MAP for smoke and boost control - I've done it, it's literally a switch and it reads a whole seperate smoke map and ignores the maf table.... On an early VAG EDC15, when you unplug the MAF sensor it does the same as ours do - reads a default nominal value, on the later ones it reads the map based smoke map as above. I expect it temporarily "flips the switch" but, they use EDC15P - which has a bunch of other features which C2 doesn't. One of which is, I believe, to be this. Maybe I'm not looking hard enough - I'll keep hunting.
I have chopped a maf sensor off, and soldered directly onto some wires. It meant re-jigging the smoke map MAF axis, but it should work. Haven't had time to test it properly yet.
At the end of the day, if we have to have 2 map sensors, so be it... but it would be nice to only use 1!!
