    Hello everyone. Is. There a way known how to change the range of the system charges the HV battery when the. Car is Idling?
    The car usually charges the battery when it comes to 40% and stop charging when it comes to 50%. What a I would like to do is: set the system to start charging the battery at 50% and stop it at 60%. Does anyone know a way to do that? Via techStream or other any parameter?

    You'll be going into the firmware and the system and having to make changes That's what I've been asking about for some time for some other things but I guess people still don't like to do that I guess it must be prohibitively expensive or reinventing the wheel or something I guess that's why people that are modding and doing extreme things to vehicles by aftermarket computers to run the engines and stuff like electromotive systems tech 2 and 3 which from what I understand now are obsolete things like mega squirt and what have you are popular because they're open source and everybody can play with them but you go into Toyota software where are you going to begin you'd have to dissect the whole system and rewrite and redo I can't even imagine..

    Your fuel efficiency will be awful because ice engine will be running more during city driving. At least ice will be up to optimal temp
