thats exactly what I did...works fine like that

 

Nah. Pro Gauge simply interprets what EMS sends to it. Setting it up in the telemetry wizard is what tells EMS what you're sending too. You actually have to go a step further in AEM Pro and look at the telemetry setup. This is where you define what data you're going to be sending to devices setup in the telemetry wizard. Pro Gauge just defines what to do with the data being send to it. Go into AEM Pro, Setup, Advanced, Telemetry Setup and you'll see what I'm talking about.

If you're talking about Engine Load, that's actually measured in kPa. I'm not sure what this is measuring. It's definitely not boost. Since you call it Engine Load 2, maybe your tuner set it up or something? I would think true boost in PSI can only be read off the MAP sensor.

 

Anyone ever figure out how to get the serial gauge to read boost in psi?? I've searched forever and haven't had any luck.
