I use latest P3Dv4 with HF2.
I set up the FMC in this case it was EHAM-EGLC Acft: E190
39.5 tonnes in TOW
Did put in weight (ZFW, FUEL and TOW in the PERF page in the FMC)
Wind at EHAM at the time 190/7kt
Temperature outside 8 degrees
RWY24, full length, at EHAM with SID VALKO1S
Did activate FLEX TEMP in the FMC and pushed enter that is highlighted in the FMC, (long rwy, so TO2, and Flex 40degrees)
Flaps 2 takeoff
N1 with TO1 was 89,9%
N1 with TO2 was the same 89,9%
When flex added in this case 40C, the N1 should be reduced to like between 78 and 81% N1
Nothing changed at all, it was still 89.9%
Did the exact same way as I did on the "old" Ejets, and there flex worked just fine.
On the return from EGLC back to EHAM, same procedure, TO1 because of the short runway at EGLC, Flaps 4 for takeoff.
Nothing happened, still 89.9% even if i swapped between TO1 and TO2 the N1 did not change at all. In this case it should at least change N1 between TO1 and TO2, but same value.
