If you're watching the factory temp gauge for engine monitoring; I found that the Dash Needle Never Moves while actual engine temp swings from 175 to 205F!
For those who like more details, read on. . .
Local temp is 101F. Air intake through the MAF on the stock 1MZ intake is 124 to 128F. With the AC on during extended idle condtions the engine temp is 185 - 190F. With the AC off the temp increases to 205F.
The ECM reports a 7.5% Calculated Engine Load (CEL) increase to run the AC compressor and fans at idle. Idle trims are as follows.
AC ON, CEL = 26.7%, LTFTB1 = 9.4%, LTFTB2 = 7%
AC OFF, CEL = 19.2%, LTFTB1 = 7%, LTFTB2 = 8.6%
