Hello all! I created a way for folks with afterburner detents to easily generate custom user curve numbers so that the MIL location of their aircraft perfectly aligns with their throttle detent. My original creation was in the computer language I am most familiar with - Microsoft Excel. Fortunately, one of my first testers was community member Bailey who has made several fantastic apps. Bailey's testing help expanded into a full collaboration, turning my calculator into the standalone program that you see posted above. The utility has been tested with multiple controllers and multiple detents.

 

In the User Files download you'll have both the standalone and the original Excel versions of the calculator that you may choose from, as well as a ReadMe that shows how to find your physical detent location and generate the numbers that you will put into your DCS axis profile.

 

If you would like to check out the code, head over to Bailey's GitHub here: https://github.com/asherao/DCS-Detent-Calculator
Also, find more of Bailey’s work on the DCS User Files site. https://www.digitalcombatsimulator.com/en/files/filter/user-is-asherao/apply/

Feel free to reply in this thread or reach me on Discord, username JCofDI#7932. (uppercase i)

 

Thank you very much for your time. Enjoy the flights!

The instructions for finding your detent position have to be read and followed carefully for this to work (not a complaint, a friendly heads up).   For my warthog throttle, the afterburner detent position is 25.  I have the 3D printed push over detent from shapeways.  Previously I had a curve of about 5 set for my F-14, 3 for my F/A-18.  So far, this seems to work a little better.

Any chance of sharing your current curves for the F-14 and F-18?

I used the ones from the spreadsheet.  The download is both an executable and a spreadsheet.  If you are worried about running software from an essentially unknown source, the excel spreadsheet seems to work fine and should be able to be ran in Google sheets.

Glad to hear you had a great time (and that the spreadsheet got some love 😄)! Thank you for the feedback on the readme as well - I definitely considered trying to shorten it to more "bullet-point" steps, but given how critical that detent location number is I didn't want folks to rush it. Maybe worth taking another look though when I get some time.


Also, just as a quick follow-up to your second post - I have tested and confirmed that Google Sheets works when uploading the spreadsheet from the download. In case anyone else was wondering, that should be a perfectly valid way to use the utility.

@stag1978Thank you for checking it out, and glad you found it helpful!

 

One of my favorite parts of the tool is that now that I have the formula all set, it should be an equally short amount of time to set up a new plane in the system. Now I just need some more afterburning planes to get released in order to prove it! 😄

My throttle has an idle/off detent as well so I have some X axis saturation dialed in to prevent the throttle from spinning up until after that detent.  The axis is also inverted.  Is there a way to still use the excel sheet for the after burner detent?

Worked a treat for me, thanks!  Finally got a new computer, having to set up my modules again. Old curve was close, but not as good as it could be. I used the calculator, curve is dead-on now.  I highly recommend this, saves a lot of time and effort to tweak the curve manually.  BTW the calculator is truly stand-alone, doesn't install anything, and I got no hits on any anti-virus check.  Just be sure to download from the source above, and not a 3rd party.

As-is the sheet does not account for this setup. Just doing some quick testing now that I'm back from weekend travels, I believe I could modify the Excel file to account for these more niche options. Getting around to making and testing the formulas for it may take me a few days with my current schedule however, but I'll get to it when I can and let you know.  Thanks for the idea and interest!

 

 

@BlackLibraryThank you very much! Glad to hear it's a hit with the wingmen too! 😄

 

@Faelwolf Thank you for the kind words! It's this sort of multi-module adjustment I was hoping to find a solution to when I started working on the calculator (thank you free trial events! 😁) so I'm happy they all worked out! 🥳

This tool worked flawlessly for my Warthog throttle but as mentioned by @j9murphy I now have a CM3 with an idle/off detent and it is inverted so the numbers don't work unfortunately. I used X saturation to setup the AB. Would be great if it's at all possible to cater for this setup in the tool too.

@zildac Thank you for the kind words! Congrats on the throttle upgrade - had I realized that the CM3 was an inverted axis I'd taken extra steps to include it earlier 😅.  Better late than never though - hopefully I can get you back to perfect tunings in no-time. 🤞

 

If possible, can you and @j9murphygive this spreadsheet version a trial (and any other users who would like an inverted or saturation-limited option)? It's currently a "working copy" so please take care to only adjust the highlighted "input" cells, but all planes should be set to function correctly with it. If you want the curve inverted, place an "X" in the appropriate cell, and if you use in-game X axis saturation limits then please put your value in that cell as well. The detent location should still be found the same way as in the original readme doc and no user conversion required on that - it's all handled in the formulas.

 

If you are not able to use the spreadsheet version you can include your plane of choice, detent value, and saturation setting in DCS and I'll reply with some curves for you to try. Please let me know how you find it and any issues you come across, as it's tricky to self-test with only one throttle at my disposal!

Many thanks @JCofDI I'll have a play with this later! 👍

 

Hi, So I tried the new sheet and the AB location is quitre early in the throttle travel. I removed my saturation setting, but I have to keep a deadzone of around 4 in order for the rear detent to not cause the engines to spin above idle.  Perhaps I am doing something wrong?

@zildac thank you so much for the detailed post - I don't believe I expected DCS to change some values based on what it perceives the "positive" side of axis to be and that's what's causing the issue (might just have to see if I can invert my throttle to test it more thoroughly myself 😄).

 

In short the curve isn't actually following the basic direction I thought it would. To help make sure I'm tracking, would you mind providing the following? Be warned I fully do not expect these changes to make the curves usable 😬

 

- head to a plane you don't use much and assign your throttle axis to the thrust so that everything is default, then enable slider and user curves then take an image. 

- with above settings, put your X saturation to 50 and share the image

-with above, check "invert" then share the image.

 

With those three I should be able to get a solid grasp of how DCS is using your numbers and be able to make some modifications. I really appreciate the feedback and help!

Hi,

 

No worries, you're welcome and thanks for looking into it. I can try this on the F18 (I use it mostly) but it's easy enough for me to revert to working curves tbh, it's 2 minutes effort. I'll post below once done 👍

 

@JCofDI

Please see below, these are from the FA18. You'll notice that at the idle/rear detent my throttle needs a dead zone of 4 hence the non 0 value in the first pic

 

OK, please see below, any questions at all or if you need extra info please just shout and I'll try and help.

@zildacthank you much! I think I see the cause of the issue and hope I have a path forward to fix it. As a pseudo workaround to test my theory, you can try these curves with the "Inverted" box in DCS checked as needed, and a Deadzone of 4, with X saturation 100: 

0
10
21 
31 
41 
51 
62 
72 
82 
91
100

@JCofDI You're welcome! OK cool, thanks I'll try your suggested values and post back results 👍

 

Those values are much better, the 1st stage of AB is coming on about 2-3mm past the physical forward detent, but much better than the values in the XLS from earlier. With the original version of the tool and my Warthog it was MM perfect tbh, but this is still very good!

@zildacGlad to hear it! I'll keep fine tuning now that I know I'm back on track and hopefully get you right on-lock for that detent again. 😄 Hopefully by this time tomorrow I'll have a new version of the sheet to break horribly test. 😬

 

I think the last thing I need to know would just be making sure I understand the idle/off detent. It's set up in the VPC software to use a "range" of the axis to fire the "off" button, right? Do you set that range in the software using a percentage of the throttle axis? (For example: 0-5% range = Hold "End" or a similar setup?) Or are there already physical buttons past the detent like on the Warthog?

@JCofDI Excellent thankyou, happy to test for you 👍

 

You're right yes, so the Warthog has the physical buttons on the idle detent but on the CM3 you set an axis to button based on percentage. Mine is set to 0% to "fire" the button press. As a result I need to set a DZ in the Virpil software too as the physical idle/off detent is very close to 0% and it's easy to pull back to idle and trigger the button/s. Hopefully the screenshots below explain:

The deadzone is set slightly different on each throttle as they read slightly different values when unlinked. Hope this helps!
