We put an EU in my car last night. We hooked up the wires to log coolant temp and intake air temp. Now, I get really low readings for the temps. At least 30* off. Before we put in the EU, It would normally read around 180* for coolant temps, and IAT were usually around 15* over outside temp. Has anybody ran into this before? I have been monitoring the temps via a greddy informeter, which reads right through the obd2 port. We went over the wiring a few times, and everything looks right. Could hooking it up to the EU cause such a voltage drop that its not getting the right readings?

 

There is a setting in the parameters section, where you can toggle between various styles of temps sensors. Did you try playing with that?

 

I dont know. Charles(phunk) was the one setting it up. I am sure he will chime in later after he wakes up.....lol
