I've been following the various threads over recent months about using NOS, propane etc on TDIs.
What I don't fully understand is how this fits in with ECU mapping.
Am I right in thinking the ECU is mapped to assume NOS and/or propane is always in use ?
If so - what happens if you run out or turn of either of them - presumably the mapping is then far from ideal, resulting in mucho overfuelling, smoke etc ?
