Hi. I just put on my car a LPG system. But i have a problem: in order to set the modules for the lpg, they need the car with the termic engine on , on idle. How can i do that ?
Maybe make a spoofer that would fool the ECU into thinking that the coolant is cool? That way you don't have to use the defroster or heater: A Prius ECT Spoofer MCU Controlled | PriusChat SCH-I535
Maintenance Mode is the correct procedure. The same as disabling traction control. The engine will start and not turn off until power is reset.
