[Land-speed] While I am between parts and weather...

[Larry Mayfield]

Ok, guys, I think I have a solution that suits my needs! many thanks to 
all who supplied information. Solution looks to be a simple speed 
control system from a 1997 Ford Ranger pickup ( I have one I drive 
around and a manual, lol)

Many thanks to all!

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...
