Hello, this is my first time switching to an aftermarket ECU and I’m confused when it comes to gauges. I’ll be using a 1500 or 2500, and I want to use an AEM water temp gauge, oil pressure gauge, and boost gauge. My thinking is, how will the ECU read those parameters if that info is only going to the gauges?

 

All of the AEM gauges have 0-5v analog outputs. Those can be fed into the Haltech ECU. Personally, I would skip the AEM gauges and use a single Haltech multifunction display while feeding the sensors directly into the ECU.

 

I considered using the Haltech IC7, but I do not want to have it sitting in front of the gauge cluster/replace the gauge cluster with it. Seems way too bulky to mount anywhere else.

 

Haltech also offers a gauge and i believe this is what C.ludwig is referring to
