I can't provide any specifics, Mayf, but whatever you do use, I'd provide
for a manual override in case things go awry.

Subject: [Land-speed] While I am between parts and weather...
I have been dangerously thinking again. run for the hills, now, before
it is too late!
Well, ok, I am building a dyno set up for my own personal fun and use on
motors I put together. I have been looking at electronic throttle
controllers but admittedly, I am pretty ignorant on the technology. I
now use a long Morse cable to twiddle the throttle but I'd like
something that might be more amenable to using software for control.
So, the question. I am guessing that most are fairly simple in concept,
that a pedal moves a pot of some sort which has a module which controls
voltage level into a servo motor control output which rotates the
throttle shaft. At least, that's how I would tackle it. I think that
because I would want to use this on more than one kind of throttle set
up that the servo portion should be, at least, removable and be capable
of having some sort of lever attached with a link to a regular throttle
shaft. That would permit use on multiple kinds of throttles with only
some kind of attaching bracketry. So the basic question is: what's out
there for selection at the pick a part places? What should I be looking
for for something to play with? Any partiucular brand that works better
than others? I think that I would need to get the gas pedal assy with
any electronic pieces, harness and cabling, and a servo motor/throttle
body set up all from the same donor. I am guessing that the simplest of
systems would be best, something without control inputs being required
from the car/truck main brain box in order to function.
While I have no plans for utilization of a system like this on the
Sunbeam LSR car, it seems that these would be almost made to order for
the special construction class cars and maybe even some of the door cars
as well. Would there be issues with using something to return the
throttle to closed blade position if something breaks or goes south or
does a servo used in an application like this do that automatically?
Listening for thoughts and ideas for my dyno application... like I said
would be nice it it was a simple pot type control voltage to a module
that converts to a drive output for the servo. I have software that can
generate an automatic input for a dyno ramp up and down pretty easily...
hanging around in the cold, in the wind, without the next parts for the
Tiger refurb, waiting on football...
