Right, but it isnｴt a lot. My car (BMW 523i E39) consumes a litre per hour while idling with a warmed up engine. I have a analog fuel consumption gauge, and I learned: If it is on about "4 l/100 km"...

AFAIK the cost of cycling the battery is a lot higher than the cost of running the alternator, so that panel better be supplying the full electrical needs of the car, which is a tall order.

I believe you're right, it definitely seems like it would have a poor effect on aerodynamics. I can't really speak on exactly how much of a negative impact it would make though.

Fuel pressure is a good bet. It's tuned for around 50psi. If you wanted to do a 5-10 minute drive with logging running and send it to me, I'd be happy to push some tweaks and we can see how it does.

What you're looking for is the "IACV duty cycle" slider. It affects the IACV for both hot and cold idle, but you can partially compensate for hot idle with ignition timing.

I don't know anything, but I'd think main concerns with low idle have to do with alternator power output, AC cooling ability, and NVH concerns.

Low idle RPM shouldn't hurt it. What hurts an engine at low RPM is when you put load on it (i.e. lugging the engine). Long as it has oil pressure, you should be fine.
