LVAR Offset for throttle axis

[Adamski]

A thousand apologies if this has already been covered (I couldn't find it). It's been a *long* time since I did any LUA programming - and my grey cells aren't what they used to be!!

I suffer from the dreaded Logitech X-56 "throttle creep" and used to use a LUA script I wrote to disable all throttle inputs when in autopilot, using the offset 310A.

The scripts (on/off) appear to work (and write a value to that offset) but the throttle remains active.

Does MSFS use a different offset? If so, how can I find out what it is? I've Googled without success, but think I should be able to track/trace it when flying ... but how?

TIA!

Adam.

No, the same offset is used.

What aircraft are you flying? How have you assigned the throttle? Could you show me your lua script, FSUIPC7.ini and FSUIPC7.log files please. Please add offset logging for offset 0x310A (as UB in hex), and once you have set auto-pilot please activate logging for Axes Controls.

Thanks, John (and hi!!) ... you're quite correct, as ever.

It turns out I was forgetting to pass the axis through FSUIPC (I'd been fiddling with Axis & Ohs) .... mega DUH!!!

I wrote the scripts almost exactly two years ago ... I'm amazed they still work, LOL!

I'm amending it so it can work across the board (without checking for autopilot engage y/n) - mainly for the aircraft that use detents (FBW A320 or Fenix A320) where it's easy for the throttle to creep out of the slot.

I think a more effective solution would be to do a hardware mod on the throttle (clear the jelly/gloop). Unbelievable how Saitek/Logitech produce this expensive cr*p!

Thanks again,

Adam.

Hey can you please give me the solution on how you got this resolved. I am also in same boat of throttle keep on moving around during flight.

Plus can you please tell me what is this hardware mod you are talking about thanks.

The OPs issue was not with FSUIPC - he was using Axis and Ohs. His problem resolved when he switched to using FSUIPC.

First, check that you have removed any throttle assignments in MSFS - I recommend using an empty profile for your controllers in MSFS if assigning in FSUIPC, but it is also possible to mix-and-match your assignments, i.e. have some in MSFS, some in FSUIPC. But you will get issues if you assign an axis (or button/switch) both in FSUIPC7 and in MSFS, or in any other software. Axes, as well as buttons, keys, switches, etc, should only ever be assigned in one place.

Also check your MSFS assistance options -some of these can control the throttle for you.

If none of that works, please show me/attach your FSUIPC7.log and FSUIPC7.ini files and I will take a look. No additional logging needed initially, but I may also need to see a log file with logging for Axes Controls activated at some point.

That is a question for the OP - when a question is for a specific person, you should tag them so that they get notified. So hopefully @Adamski can respond to this question.
