2 varying inputs to control one output?

Not sure exactly what I'm looking for in terms.

I want to control a pwm output to control a vgt Turbo actuator. I have inputs both 5 v off the map and exhaust back pressure. I want to keep them as close to 1:1 as possible or slightly higher. I have not got a controller yet or the Turbo as I don't see the need to waste 350 dollars on something I'm not gonna be able to make work.

Is the software capable of taking 3 to 4 inputs as I'd like to eventually tie in throttle pos and rpm to refine the tunabilty down the road and determining an output if you tell it which way to go to make them match. Rpm and tps would be more for off idle tuning then anything to prevent the vanes from going wide open with the very little bump of the throttle.

Any bump in the right way would be appricited. Term to search for or a link.

Thanks guys.

"The software" is capable of doing whatever you program it to do.

The Arduino has 6 inbuilt ADC inputs at a 10 bit resolution. It is capable of complex mathematical operations. The results of those operations can be uses to control different outputs in many different ways.

Can you do the math? If so, then you can do it with an Arduino*.

Makes sense. Well looks to be my next step then is figuring a nice formula to keep the numbers where I want. That's what was throwing me and reading the tutorials I found made it more confusing.

Thanks
