hello,

do you have a guide on how to setup the idle up pin? i can't seem to make it work.

tried grounding the IDC pin 36 but rpm wont rise
also tried selecting different IDC pin like 35, 47(proto area)

idle control:
PWM open loop
1 output

idle up settings:
idle up enabled - ON
idle up pin - 36
idle up pin polarity - normal
idle up amount - 15%

Hi, welcome

Can't say I've much experience with idle, as I haven't got that far.

I think the guys are going to need a little more information about the type of idle you have. How many wires does it have? Do you have a part number? If its a standard pert for your car, what car is it? Perhaps post an image. :)

as far as my understanding the idle pin needs to be wired with the ac compressor trigger (ground or positive), once it is triggered speedy will know that the ac is on and will automatically increase rpm % based on the settings without the idle up valve.

i just can't figure out on how to set it correctly and if my theory is right.

Yes that's true. It's arduino pin. And also remember that there is no protection of any kind when connecting directly to arduino pin. And also the arduino pins can't handle +12v, so if the AC-control wire switches between 0 and +12v, it can't be directly connected to arduino idle-up input pin. There needs to be circuitry to protect the arduino and keep the line vomtage between 0-5volts. There is many ways to do this like for example use resistors to do voltage divinding and offer some protection and diodes can be used to clamp the voltage to below 5v. Or opto isolators can be used too for example.

selected A15 in the idle up settings, when the engine starts up its already triggered and when grounding the A15 nothing happens.
