Axis cailabration doest not show movement for #3 throttle.FX

[percy]

I using a two throttle input and need to map for engines 3 and 4 but the #3 engine does not show any movement, 1,2 and 4 are ok. (axis calibration page)I have reloaded FSX, fsuibc4 4.203 and go flight, problem is the same with Air Bus 340, PMDG 747 or FS 747. Number 3 also does not show movement in fsuibc even when using a keyboard. Using Vista 64 and FSX with sp1, FS9 maps ok. Not sure what to check next.

Thanks,

If you have two throttle levers, and select the FSUIPC option to map 1 -> 12, and 2 ->34, just ignore the Joystick Calibration entries for throttles 3 and 4. They mayt show something or they may not. It is just the way the simConnect intercepts work. All you should do is calibrate your throttle 1 and your throttle 2, both on the left-hand part.

It gets complicated as your 1 goes to 1 plus 2, but 2 has to be stopped from going to 2 and made to go to 3 and 4. But that happens in flight mode, not during calibration, where you are calibrating YOUR throttles, not the 4 end results.

I know it was more obvious on FS9, but the interception and control was a helluva lot simpler in those days. Even then you still calibrated 1 and 2, not 3 or 4.

Thanks Pete for your quick reply.

I think I can make this clearer as to what is happening,

when I map 1-12, 2-34 when I move throttle 1 engines 12 and 4 move, when I move throttle 2 engines 2 and 4 move engines 3 does not move with any throttle input.

This is in the Joystick Calibration screen, right?

As I though I said, or tried to say. Just ignore Throttle 3 and 4 when you only have two throttles. Calibrate Throttle 1, ignoring throttle 2. Then calibrate Throttle 2. You only have two throttle levers!

If I had realised such a simple thing wouild cause so much confusion for you I would have put in the extra code to simply stop Throttles 3 and 4 moving at all when calibrating, and maybe also Throttle 2 when calibrating Throttle 1. But it is extra code, and i really thought it unnecessary. It is easy to calibrate correctly if you simply calibrate the throttles you have, not where you are mapping them to go!

I've just had another look at this, comparing what happened on FSUIPC3 and FSUIPC4:

In FSUIPC3, with FS9 or before, with mapping 1->12 and 2->34, no matter how you assign the axes (whether in FS, in FSUIPC via FS, or in FSUIPC direct), on the 4 Throttles calibration page:

1. Moving Throttle 1 shows values changing on Throttles 1 and 2.

2. Moving Throttle 2 shows values changing on Throttles 2 and 4.

At no time does Throttle 3 move, but that's totally irrelvant because you aren't calibrating a throttle 3 -- when you use this Mapping you only have two active throttle Axes, and it is those you calibrate.

Now, iIn FSUIPC4, with FSX, with mapping 1->12 and 2->34, no matter how you assign the axes (whether in FS, in FSUIPC via FSX, or in FSUIPC direct), on the 4 Throttles calibration page:

1. Moving Throttle 1 shows values changing on Throttles 1 and 2 (not 4 as well!)

2. Moving Throttle 2 shows values changing on Throttles 2 and 4.

At no time does Throttle 3 move, but that's totally irrelevant because you aren't calibrating a throttle 3 -- when you use this Mapping you only have two active throttle Axes, and it is those you calibrate.

Now, there's a striking similarity between what happens in FSUIPC3 and FSUIPC4, isn't there? In fact as far as I can tell they operate absolutely identically! (This did surprise me a little, as I had thought there were some subtle differences).

In neither case does any of this stop you calibrating the two throttles, as you should, and the mapping works perfectly, 100% on the actual 4 throttles in a 4-engined aircraft.

If you are seeing different results to this, with the latest FSUIPC versions, then please check that you aren't getting double assignments, both in FS and FSUIPC. That can create havoc.

Hi Pete

Thank you for your information. When I used FS9 I calibrated in FS not fsuibc and I just assigned the mapping and all work fine. I tried to do the same with FSX and that is when I was unable to get #3 to move, after reading your info I calibrated in fsuibc and then mapping worked fine as you stated. I have a home built throttle assy and after calibrating with fsuibc the first part of lever movement shows little N1 increase and I had trouble with Engine reverse so in FS I assigned my #2 throttle as #3 calibrated in FS and then mapped in fsuibc so now #1 moves 1,2 and 4 and #3 moves #3 only, all is working fine,. Thank you.
