This reward module likely doesn’t provide any range benefit beyond what’s already available, it just powers on faster.
I suspect that as well.
I did took a look at the double engineered seeker rack.
It has the mass of the lightweight ones, 0.4t - so nothing additive/multiplicative there, they simply took the best value and that was it.
But the power consumption was interesting - it was additive. So they took the -40% from lightwight and +20% from high capacity and we have only -20% power usage on the module. Also interesting, it has better Distributer draw - -40%, no idea where that came from. Lightweight doe only -35% and high capacity does not touch distributer draw
So i'm quite curious what stat the fsd reward will have and while it can go to places, i do think it will have the same range, 2s boot time and +20% heat. Probably the same integrity as long range blueprint too..
