DFP Throttle issue
« on: May 30, 2009, 04:24:12 am »
Tonight I wanted to do some STCC practice.  When I hooked up my wheel and got into game I found my throttle pedal sticks on full all the time.  If I hit the brake it will release throttle.  I've checked my profiler settings and combined axis is not checked.

Do any of you know what the problem could be?

Do you mean it physically sticks on full as in it won't return or electronically it won't return?

Electronically as soon as I touch the throttle it slams to full.  But the brake pedal will back it off based on how hard you push.

Is this a dfp you had for a while? Almost sounds like someone tried to do the cord fix on the pedals and put it back together wrong maybe?

The pedals are mine, the wheel is used.  Worked when I tested in GTL though.

I get that sometimes marcus, I get to my pitstall and can hear the fucker screamin'! normally touching the brake cures it for me, and it's fine after that for days...

*edit* i did check the white graphical representation bars thingy once, and as soon as I touched the pedal it hit the roof, you probably did this, but try re-calibrating your pedal in game, making sure you push it all the way...

Be sure when configuring the pedals in game you do the BRAKE first then the throttle. it can help in with some issues.

 I've had a DFP for about 3 years, I find every year I need to pop open the pedal case and spray some electrical contact cleaner ( or not as good: WD40 ) inside the potentiometers...as well as clean out lint/dust ect


 every time I have throttle/brake issues, that has fixed it up...seems to be about once a year

I also have a DFP, and i've had throttle problems as well.  The problem I have is the throttle not responding at all when I floor it.  If I release it completely and step on it again, it usually cures it.  Sometimes I have to do it twice to fix it.  Opening them up and cleaning is a good idea, but in my case it did not solve the problem.  The second time I opened them up I noticed a small crack in one of the little plastic pieces that holds the potentiometer for the throttle in place.  The pot wasn't being held securely and I think the whole pot assembly was sometimes moving when I hit the gas, rather than just the 'knob' moving.  To fix it I put a tight fitting spacer in between the two pots and now they're fairly secure.  Sometimes I still have the same problem, but it is very seldom now.  It might happen once every two months, rather than 5 - 10 times each race like it was before I fixed it.

I don't know if your problem is similar Marcus, but it wouldn't hurt to check.  Also, vacuuming them out and spraying the pots with contact cleaner is a good idea too.  Although the fact that hitting the brake fixes it does make it seem like it could be software related.

I am having a problem with my peddles. And it is the pots that are the problem. Mine isn't as extreme as full throttle. I use this program to tweak them. Maybe some of you know this DX Tweak.

The red markers on the slide scale are the accutual pots reading, The black is the ones I use to change the scale's lower and top setting. I am using a Momo so my pots are scaled at 255. You can see how much they are off.




I don't think this DX Tweaker can fix the problem. It does sound like a potentiometer problem. Did you try just to stomp your foot on the base instead of the brake. If it releases I'd say 100% pots sticking. I think Peter Enqvist & ummagumma idea of cleaning it and greasing it up again is worth a try.
