  Rotax 914?

I would strongly recommend 4 EGTs. They don't half dance about with changes 
in throttle setting. Probably due to the manifold/butterfly interaction. It 
may be less of a problem with the 914 because the inlet air temp will be 
higher and help to evaporate the fuel droplets and distribut the fuel to 
the cylinders in a less random manner.
