Here's an EXCLUSIVE look at the development of the throttle controller.
View: https://youtu.be/KVogEmmQZTs

Nothing special here, using a PWM motor controller and a pot to control the throttle.
Will start working out the rest of the system, checking the two tps readings, reading throttle pedal as well as receiving CAN input from the ECU for idle control.

When your done playing around with that thing we need to talk... lol i can build the circuits just fine but i need access to the source code, I can see myself doing Two of these TB on one intake manifold.... :cautious:

Shouldn't be too hard to do. I need to scour the net for what these things are supposed to sound like when holding a position. So far the quickest response I've gotten is by opening at 100% duty cycle till the tps and the aps match positions and "closing" with a 0% duty cycle and using the spring. I think I COULD reverse the motor and drive the flap closed but idk if that complication is even worth the effort. I need to work on the holding a bit more as right now it seems noisier than it should be. This comes down to figuring out what duty cycle is needed when tps=aps.

I ordered an enclosure and some panel mount plugs to start finalizing the hardware. Adding can is next on the list too.

I started shoehorning in the arduino, the motor driver and the CAN communicator into the enclosure. I picked up some 8 and 10 pin connectors cheap on amazon too, they were cheap but they appear to be decent quality. Only have a couple more wires to plumb in and the rest of this is just coding.

looks sweet! do you plan on having it ignore signals that are out of range?? if thats the case i would drive it open and have it close upon failure.
Yes. Both the pedal and the throttle have two sensors and I make sure they are within a margin of each other. If they aren't then we throw it into limp mode and throw a code. The TPS signals need to add up to 5v so that is an easy check.
