GPL: TSW+PDPI not smooth???

Hi all, Recently, I installed PDPI L4. I have TSW (50 ohm SPEC pots). No jittering, spiking - it's rock solid, BUT it's not as smooth as TSW+SB Live. My virtual wheel in GPL moves in discrete increments, not smoothly, very hard to control when you have setting to full linear. Specially hard to control close to wheel neutral position. By the way, I calibrated TSW without problem and also I set dead zone to 0 using CTFJ!. Didn't help. It's hard for me to believe that TSW+PDPI cannot better TSW+SB Live in smoothness. So my questions are. 1. Is that matter of fine tuning in PDPI Default/FineTuneInfo registry settings. Currently I have "FineTuneInfo"=hex:3b,00,00,00,3b,00,00,00,3b,00,00,00,3b,00,00,00 (exported from my registry). Can anybody who have smooth respond with TSW(SPEC pots) and PDPI send me a FineTuneInfo settings? 2. Is there anything else I can do to solve my problem. Like special registry settings, magic calibration... Otherwise I'll be forced to go back to SB Live gameport which gives me little jittering but allow me smooth control with generic Papy driver and steering set to full linear. I really hope that I'm doing something wrong and PDPI is rock solid and smooth, as so many people in this news group said it is. I'll highly appreciate any help or suggestion? Thank you in advance. Darko

I have a tsw2 with spec steering pot and pdpi. Steering moves smoothly in gpl, NO increments. I have the switch on the pdpi set to digital. I have done no special calib or tweaking. My default fine tune reg entries are the same as yours. I also have a sb live. I'm using dx 6.1. Maybe Thomas or pdpi can help you. > Hi all, > Recently, I installed PDPI L4.

I am using 20K pots, and I definitely had to adjust the register of the PDPI FineTune section. First of all, make an folder in the FineTuneInfo section bearing the same name as your controller. Then make the keys in that folder required (have a look at the keys in any other folder in the FineTuneInfo folder, copy name and content). You now have a register setting that you can experiment with Darko, 3B in the fine tune register is way too little sensitivity for 50 k. I am using 10 for my 20k pots! So, 20 could be a good value for 50k pots. If you are using 50k pots all around you should use these values: "FineTuneInfo"=hex:20,00,00,00,20,00,00,00,20,00,00,00,20,00,00,00". You're only using 3 axes, so the last of the four "20" isn't important... You should obtain a range of 0 to 255 if you can. You just have to adjust the finetune register so that you get as big range as possible. One thing... You have to restart your computer every time you change the values... :-( Windows reads the register only when you start up windows. If you don't get it to work, you can email me, because I have a lot of experience in this. :-) ---Asgeir---

Thanks Asgeir, He sent me an e-mail, and I was just about to recommend the exact same thing :) It's also worth noting that the TSWs set their pedal pots at "mid-range" of the resistance position (position-range of the axis by default never reaches 0 resistance value). It is always wise to manually adjust the pot posts to start from 0 resistance (all the way to lock on the one side - depending on the position of the pot mounting) to reach a desired result. In fact... EVERYONE should make sure this is the case on all their pedal units (you'd be surprised what some of the settings are on some wheels). Cheers, Shumi P.S. Darko... the settings that Asgeir recommended should increase performance for you :) We would add it automatically in the drivers except that it would probably cause confusion for most since most use 100-250K Pots, and the 20 setting will not be desirable for them...

Thanks guys. I just change from 0x3b->0x20 in FineTuneInfo, and that made HUGE difference. It's just the best experience in GPL I ever have. Rock solid and smooth. This little tweak made wonder. Shumi you should put this info on PDPI site/documentation, or at least in Readme file. Now TSW+PDPI really look like ultimate combination for GPL, but just with a right FineTuneInfo settings. Once again, thank you very much for your response.

I have made note of the settings you gentlemen are experiencing favorable results with, and the new version of the drivers will include a readme.txt for uncommon pots (although they should be more commonly used). Keep your eyes peeled for our Win2K drivers coming soon :) 20K = 10 50K = 18 Cheers, Shumi

I've owned a PDPI L4 for a while, and have never seen this FineTuneInfo deal you're speaking of. Where is that?

Ok, I found that reg entry. Now, a new question. Is there a setting which would make a Thrustmaster NASCAR pro wheel smoother? I have not been able to use the Papy joystick driver since I installed the PDPI L4, my inputs are way too clunky. The Dx driver does seem to work well enough, though. But, I do remember the Papy driver beeing much more precise. TIA -- Kenny L. kenny_l AT pacbell DOT net > Hi all, > Recently, I installed PDPI L4. I have TSW (50 ohm SPEC pots).

You need to use the DirectInput... Because The PDIP doesn't do anything to the signals if you use Generic... And you don't benefit from the diminished load on the CPU either... The DirectInput (using the PDPI joystick driver) reports a number from 0 to 255 (8 bit resolution), and although displaying a lower number, it is as stable and accurate as can be... 255 possible wheel positions are more than you'll ever need... ---Asgeir---

If your rig works ok, and the ranges count around 200, you don't have to worry about anything. It is when you don't get a large range with your pots that you need to tamper with the register. ---Asgeir---

Yes, this is very important simply because we would like to have as large as possible range of the input. If your pot gives 0 ohm at zero movement, you can tune the register so that you'll get 255 different values. The PDPI is a joy to set up with a nonstandard racing rig (like my own)... :-) With PDPI and three supreme quality pots (you know, those capable of 10 mill revs), you never need to worry about calibrating again... :-))) ---Asgeir---

What do you mean with "ranges count around 200"? Give example settings for 50 ohm and 100 ohm pots to be in range of 200. I found that 18 (hex) is smooth for 50 ohm pots. Is that in the range?

I am talking about the range you get when you calibrate the thing in GPL... The range is the biggest value subtracted by the smallest value. That is why getting the smallest value at the "unactivated" position is important: You can tune the register so that you get as close as you want to the 255 different values... I think that for the pedals you need at least a range of 80-100. I have made my own pedals, and the brake pedal has very little movement, and a subtle change of pressure at the near bottom position should cause an accurate change of input value. So, I have tuned the register so that I get a big range (200) to ensure accuracy for even the smallest changes, especially at around the threshold pedal pressure (Hehe, my brake pedal needs a heavier foot than my real life car!)... The throttle needs less range, I'd say that you can't feel any difference between a range of 50 and 100... The steering needs as much accuracy as you can get, I would say that it should use 200 - 250 or so to get as accurate steering as possible. ---Asgeir---
