Hello,

I was wondering if someone here have the AEM Serial rs232 protocol.
I have called AEM and send various emails , and they said that they don't have the info cause they discontinue the product.

Basically i want to connect an Arduino to all my devices so check the status of the parameter in one single screen.

And now im need to find out the AEM Serial protocol to accomplish that.

I also have search lots over the web , and no positive results.

I now that some 3rd parties brand have is , for dataloggin system or digital dash or gauges.

I will happy with any help and i will also try to share how i will develop the 1din screen to install it over or under the stereo of the car.

And it will be able to connect to any ECU including OBD2 OEM ones (Not for rotary obviously)

 

Did you ever figure this out? I'm interested in doing the same with ESP-32 LCD screen
