The only way to get quick heat from the 616 - 617 is a block heater.
Heat generation at idle is relatively low, air flow, and ambient temperature seriously impact the time required to reach operating temperature.
Partially blocking radiator air flow, and brake torquing the transmission will speed up the process.

It does normally idle in that range, once the engine is warmed up a hair.The block heater does work and is plugged in during the nights and on a timer that runs from 2am to 7am (617 leaves around 630AM, my 602 leaves around 7)
I think a lot of the stalling issue has to do with the fact that I probably have 15w40 oil in there still. I think if I changed that out for some 5w40
My 602 can idle for 10-15 minutes and give me some heat at the vents, the gauge does not show much heat but the ambient temp in the cabin is more comfortable and tolerable.
That's my goal with the 617, using the proposed "idle control" system, bump the idle to 1K or so for 10-15 minutes and get a more comfortable temp in the cabin.
It might not be an absolutely necessary little device but I think it could have its uses and be fun to design/implement.
