As the title states, I cannot get EPR to engage on takeoff roll. I haven’t had this issus until the most recent update. Any advice? Does it work for everyone else?

Try engaging it after you lift off rather than on the take-off roll

It activates after liftoff without selecting it.... The issue is that its pretty standard to select EPR/N1 just after beginning the takeoff roll per the FCTM. I appreciate your help though!

So for me, I advance my throttles to 100%, than hit the EPR button.  EPR should roll the thrust setting back to the SEL temp.

I do mine after I have rolled out on take off thrust and climbed of the deck. Never had a single issue.

I often press the EPR button at the start of the takeoff roll, without using the throttles. Other times, I advance the throttles slowly to 100%, then press the EPR button. Either way, the EPR engages for me.

That's my way of take off too. Not been a single issue.

An addition to my previous post.....

Yesterday, after advancing the throttles to 100%, and upon reaching 80 knots, I pressed the EPR button, but it failed to engage! It only engaged after takeoff, and at 400ft AGL, I pressed the AP button, then LNAV, and VNAV (it was turning on the VNAV that engaged the EPR). This was in the newly installed 757 III freighter for FSX-SE. I'm just telling which version it happened in, because I generally find that the performance of the 757-III is the same across all platforms (FSX/SE/P3D3/P3d4), of which all are istalled on my computer, but with FSX, I can't activate SP2, or Acceleration in Windows 10 at the moment.

I must admit that I switched to turning the VNAV, and LNAV on after switching the AP on, due to an earlier problem, where having them on, and after takeoff turning on the AP, the 757 turned them off, and used VS Hold, HDG Hold instead. I haven't gone back to the old way, but I really should have (I got into a different habit :O). That could be the reason why the EPR isn't engaging!

Because Microsoft in all their eternal wisdom, having dispatched Ace Studios rather disappointingly, could have turned off their activation servers, which is why most simmers these days use FSX-SE---end of Microsoft issues!!

There is supposed to be a way to get it to activate, but I've tried it quite a few times without any success. :(

Then that says it all.

Any final word on EPR engagement on takeoff roll?
it seems to me that EPR works fine of first takeoff, then if you try another take off it will not engage. Why? Do they fixed it already after many updates?

Thanks
