    Default E78 Coolant Temp Control

    Just wondering if there is a way to add the tables in 12655943 and other Cruze/Sonic Calibrations for commanded engine coolant temp as related to the electric thermostats that the Cruze and Sonic are using. It appears that these engines run very high temps. This may be a factor in spark knock and cylinder temps.

    I think GM changed the coolant temp controls on the later OS's, haven't figured out how they work yet I'm afraid.
    I no longer monitor the forum, please either post your question or create a support ticket.

    I'd like them on the e83 too, I asked hpt to look into it to but they wont be spending any more time on the e83 unfortunately.

    The weird thing with the e83, when you force open loop mode, the ect will sit on 78c. Which explains why when you go wot, thus OL the engine temp goes down. Any other time it sits between 102-106c
