Also worth mentioning I have a full 450 bucket and a spare 535 pump which I was piecing together when our global shit hit the fan last year. If anyone wants it, basically OBO.

the ekp3 can handle the load of the 295 easily but I agree if the bpm4 is the unit to get if you want to future proof it.
As ekp3's are cheap you can always carry a spare in the boot already coded to the car so if you start to have an issue you can easily change it until one can afford a bmp4.
I don't understand why the keep selling the 450lph pumps for our cars, the difference in price is marginal at best and if
your not using the full potential of the pump or lets say 50% of the flow the 295 draws less amps than a 450 at 80% flow which is about
the same flow rate.

I've actually swapped several EKPM3s in my car ... no coding was necessary. And good point - they are less than $50.
vin number and updating the ekp3 software or what ever needs to be updated through the bmw portal.
Special wrench. Most of the companies that assemble upgraded buckets sell them. Check out PR.
They're on there pretty stoutly, or at least mine was. Wouldn't want to do it without the tool.
Special wrench for the fuel line? I have the tool to open the lock ring already, but think I need to disconnect the black fueling first?
If I remember right you have to squeeze the gray piece and pull the line.
I want to be sure to get it correct
Reading your nice instruction.... " Wire the connector so white/brown and red/black." and this does not make sense to me...
On the 295 pump red wire are +. White is -.
From car I got brown/red +. And black -.
Or am I totally wrong here?

If you can hear the fuel pump priming just crank the car again. Do you have enough fuel in the tank
