Phil,

This was what Geoff and I asked. Instead of a one size fits all mapping it must be entirely feasible to 'select' a region on the GSU and have a different set of parameters used. Why should I at sea level in the UK be hamstrung because the engine needs to run in the middle of the Dubai desert. Likewise, why should the desert guys have turbines flaming out all the time because of UK sea level parameters.

As an ex programmer I cannot see why it is tricky.......

Rgds,
Mark
