I’m using an electronic thermostat - a real flap with a return spring (normally open) with a position sensor.
Right now it’s open loop low side PWM with 3 coolant sensors (post-radiator, pre-engine and post-engine) and although it’s quite fine at hunting the target, I know it could perform even better with PID. Using exactly that in my other non-ecumaster swapped car.
I would use custom DC motor strategy but I’m already controlling the honda j35 intake manifold flap (IMT) as a full bridge DC motor (with no issues and with an apparent benefit to VE).
So the question is could we have a second custom DC strategy?
Also sensor naming situation is a bit inflexible at the moment so I have to use thermostat position as a custom Stepper position and 2 additional coolant sensors as Head and intercooler temperatures which gets a bit confusing. Maybe we could get some custom sensors?
