My gas pedal has been spikey for a while now, and after it spikes it usually doesn't go up to 100%. I've tried all kinds of stuff, and most of the time it works. But most of the time sucks when one time it fails is on lap 30 of an 80 lap race at Daytona. Cruising around at 85% throttle is not fun on a plate track.
I kept my old MS Sidewinder wheel and pedals after I bought my DFP and I'm glad I did. There was nothing wrong with the wheel or pedals, it just had no FFB and a really wierd center spring system. Plus the pedals only work as a combined axis. So what to do? See attached.
