Garrett 712120 VNT Hella 6NW 008 412 actuator.
Made this up while I was bored in class.. Maybe this time I'll actually get something installed in the car before I change my mind and scrap the project again. I'm using an ethernet interface this time so I can easily test with a laptop rather than constantly reprogramming micros.. Still have the USB boost gauge I made a long time ago, so I can even use the laptop as a controller for a little while. Ordered the parts already, so if I do't get distracted by something again, I should have it built in a week or 2, but somehow I always do..
My prof looked at me like I was crazy when he saw my screen today
EDIT:
Started writing the code for this thing, has anyone confirmed if the actuator cares about the PWM frequency or not? Is it actually sampling the frequency, or just the average analog voltage? The lowest I can get my PWM on the uC is 3+KHz unless I lower the clock speed (64Mhz/4/16 = 1MHz timer frequency, but it the timer for PWM is only 8 bits). Might try feeding it an analog voltage this weekend, and if that dosen't work, I'll just bit-bang the pwm...
