When things go bad, they can always get worse... I was doing the TT and everything was going pretty well. On my best lap, coming out of the last corner, the gearbox shifted from 2nd straight to 4th (my G29 often either misses a shift or shifts up twice, never had this problem on G25 or G27...). I thought, "whatever, it's still a good lap, the gold medal is safe, let's see if I can get a clean lap anyway."
From that moment on, looking at the delta on the straights, I noticed I was suddenly losing time and couldn't figure out why. Then I glanced at the throttle bar and saw it flickering between 100% and 85% with the pedal fully depressed. Needless to say, it was pointless to continue the TT.
So, I took these pedals apart for the hundredth time (my first time doing it on the G29 after 4 years, though back with the G25 and G27 I had to spray contact cleaner into the potentiometers every 5–6 months). I dismantled everything, grabbed the contact cleaner, and sprayed it into the throttle pot. The nozzle got stuck wide open! I pressed it again but it just kept blasting almost all the liquid out. Luckily, I had some paper towels ready to quickly dab the hole and took it outside, but I just couldn't get it to stop. I ended up emptying the whole can and had to clean up "oil" all over the floor, the pedal base, etc.
At least now it seems to be working fine, but I'll get final confirmation next Friday when i do the new TT.
Since I have absolutely no intention of dealing with this circus every 6 months because once this issue pops up, it always comes back I was thinking of buying a mod kit to get rid of these damn potentiometers.
I saw some Hall effect sensors on AliExpress, but I don't really trust 3D-printed parts given the heavy wear and tear these components face. Alternatively, I could completely remove the gears and potentiometers and buy either 2 linear potentiometers or 1 linear + 1 TrueBrake from AXC.
Has anyone tried these mods/upgrades? Do they work well, and most importantly, do they completely eliminate the need for constant maintenance?
