    Hey eveyone,
    I am looking to have someone develop a circuit for me to control a Variable Geometry Turbo on a diesel engine. I am willing to provide compensation if anyone is interested. I am having an extremely hard time finding someone capable of what I am looking for, although I don't believe it is that complicated.

    here is the scenario:
    Powertrain Control Module puts out 1.26V to command the veins of the turbo wide open and sweeps to 7.15V to command the veins of the turbo totally closed, while having an infinite intervals between.

    I need a device to take the output of the PCM and mimic its readings to a actuator like this: I figure because it will also have to have the optional poteniometer shown here

    if someone feels they can accomplish this for me Please PM me or just reply here.

    Best regards,

    PS. I hope I am not overstepping the board rules, if I am please let me know and I will stand down. I am desperately looking for some help at the least.

    I am interested, and it seems like a straightforward job. Email me at <SNIP>. Check my analog design credentials by googling Ron Mancini and look at "Op Amps for Everyone" and the EDN columns I wrote.

    Sorry guys, potentiometer page

    After looking into it some more, whatever mechanical motor I use will be subject to constant motion while the engine is operating. The Motion System's product is rated for 60% duty cycle, which may not be high enough. Any motor suggestions? Thanks for the responses so far.

    Ron, email sent! Look forward to speaking with you.
