I just bought the AEM Uego gauge and sensor and and working on installing it. My question is how is this going to help me with tuning my car, (basically how does the data the AEM gauge collects get transfered to a laptop with the HP Tuner software). There are foure lead on the back of the gauge. The power and ground are obvious, but the directions say the other two are optional. Do these need to somehow be hooked up to the ecu or the the computer to collect data? So basically how do i use the gauge once i get it installed? lol

 

White wire to hpt pro box

 

There are 2 wires but I'd have to check the colors that you plug into the side of the hp tuners pro to supply the proper 5volt signal for logging. Then you create your custom aem boost pid. I rolled up my wires and put them in that storage compartment by the drivers left knee
