Could anyone running the aem v2 ecu do me a favour and have a look what their volts vs coolant temp readings are. I've a feeling mine aren't correct and the threads I've searched through do seem to back this up to a point. My coolant temps seem higher than I'd expect on the ecu and the rad hose and under bonnet temps don't seem to be consistent with what the ecu is showing, ie 198f on the ecu yet the bottom hose is warm at best suggesting the thermostat is only just open.

My ecu is showing

0.58 v 190f
0.54 v. 194f
0.5 v . 199f
0.48 v. 201f

Cheers

 

Even though AEM says the V2 ems runs the dash coolant temp gauge it does not correlate across correctly so basically if you’re trying to read your temps from the dash and compare to what you see in the AEM they won’t match. If it is that you want to monitor/see your water temps correctly without having the AEM connected get a seperate quality gauge and tap in.

Yeah, it's not the gauge I'm worried about. I'm just trying to get the accurate coolant temps, hence why I'm trying to establish what voltage equates to what temp from the sensor. There's another thread where someone's tested the voltage at various temps and compared that to the aem calibration and the aem was about 10-15 degrees out.

Once I can establish that its the calibration that's out and what temp my car is actually running at I'll be happy as at the moment it would appear on the face of things to be running hotter than I would want/expect.

 

What I can tell if your running the basemaps or tweaked basemaps in the middle it's out.

I run a v2 and changed mine from basemap, I think the IAT is out too.
