I'm Mark and I am 100% new to Arduino. I am so new that I really couldn't generate the question I am trying to ask to conduct a meaningful search here. Sorta sad, but I am now here to learn and try and complete a project I have been mauling over for a year or two now.
So, lets get to it. I am looking to control a factory servo controlled turbo. It is a holset vgt turbo. The factory servos burn out quickly and are not only very expensive to replace but also difficult to control with aftermarket stuff (so i have read, over, and over, and over again). So, the end result of this is a really awesome turbo, that is very affordable and can support a wide range of applications, if you can control it somehow.
I have looked into several different avenues, but none are great because they only provide one range of motion. what i am looking to do is to be able to have two maps, or reference tables and possibly a lock out function for on servo.
The basic layout is a turbo with a mechanical arm that will be moved by a heavy duty rc car servo that will be waterproof and located on the cold side of the turbo as to not melt it instantly. This servo shall be controlled by i was thinking a arduino r3uno that will reference a 0-5v output gm 3bar map sensor. I think that is all with in my understanding and doesn't get me beyond the 1 range of motion, but it is still awesome as i should be able to scale the servo motion to the map sensor in a very adjustable manor.
Now I guess i am finally getting to my question. if this one servo is running off of the map sensor, can i add other scales and a full open option.
trying to be clear, would i be able to apply a signal, to the board via a toggle switch or something and run a different scale of motion, and could i also add yet another signal to tell my servo to be full one direction so the turbo is max flow and i could have the best fuel economy?
I am really looking for yes or no if it can be done. Also any links to anyone doing anything similar, and anyone who has any thoughts on a better/ easier way. I am going to be moving forward with this direction as it seems to be the best option even for my one range of motion but more is always better.
Many thanks in advance and sorry for being so long winded!
