The gearing would only be to avoid the special pot that has all its action over a ahort angle in PB6 and instead be able to use a normal pot that turns about 270 deg for its action - those are more common and therefor lower in cost and probably you can choose from more suppliers and qualities.
My own throttle has the weird effect (probably due to wear) that the resistance first goes *up* when slightly depressed, before going down to zero on full throttle. I will probably at some point replace it with a standard TPS (Throttle Position Sensor) from a production car. I have bought one for $10 that is new, I believe it was originally for a Honda and the guy that I bought it from sold his car before installing the TPS. The TPS has quite different mounting than my throttle pot, but I will figure out a mechanical adaptor to position it in the same spot. I do not have PB6 since this conversion is old enough that it precedes PB6 but the idea is similar - an incoming trottle cable and a mechanism to convert the linear motion into a (small) angle op action, so my throttle has also one of the special kind of pots. BTW, gearing can in theory be done with nothing more than a piece of wire around the axle of the pot, a spring to turn the pot "off" and a spring or other relief between the string and your throttle cable, especially if you leave the original return springs of the throttle cable in place. If you want the throttle to have an easier life, you can place the pot under the pedal in the cabin. If you angle the cable or string, you might even get the increasing travel with increasing depression of the pedal. But that is a whole new project...

I actually have a Zapi controller, but it has similar issues to the Logisystems where it is way too jerky on startup. I used to have a Logisystems pot when I used their controller in a different car. I've looked, but it appears Logisystems is gone (out of business?). Does anyone have one of these pots or can tell me how to achieve the same result modifying my existing Curtis PB-6? I believe their pot box is geared to achieve the effect. Steve -------------- next part -------------- An HTML attachment was scrubbed...
