The areas that do not cause change should be ignored when setting the upper an lower limits...
Otherwise Murphy says the ecu will try to use those areas with no effect... PID loops hate dead spots.
Exactly.......
There is an exercise you go through to determine the dead spots in the idle valve movement. It takes a little time to figure that out but it is worth doing to get a reliable setup.
I went through that a year or so ago but remembering how to do it is a problem since I don't do it every day. A lot of the adjustments are only needed in the beginning and once set never change.
It takes some reading and studying to become familiar with it but it isn't real difficult.

Thanks for the feedback guys. Gonna tap the breaks and get this heat exchanger fitted before further tuning. I've tried two different heat exchangers... Third ones the charm... Unfortunately, this one is coming from China. April 15-21st estimated delivery. So I built a wooden mockup, the advertisement had good dimensions. Since I've raised the decklid, gonna fabricate a scoop to force air directly into the heat exchanger. I've noticed, while idling, air is really being sucked into the raised part of the decklid. So I think right above the dog house is the perfect location for the heat exchanger.
First prototype of the scoop... It basically reroutes the air across the (soon to be) heat exchanger.

Ok, quick update. Scoop is done (see it in the picture). Have the 1.5" spacers for the decklid. Received the heat exchanger... It fits perfectly. Only issue, unfortunately the AN10 lines are going to restrict water flow going from 3/4" ID hose to 5/8" through the radiator and into the tank. I have 3/4" OD bungs on order... My welder says he'll do it no problem.

Decklid 1.5" spacers mounted. Need to buy a decklid latch to customize, gonna need to adjust the mounting position a bit. Perfect time for me to buy a welder and have some fun with it. Mounting brackets fabricated, heat exchanger mounted... I really like the AN fittings, gonna go ahead and upgrade them to AN12 in order to keep solid flow. All needed parts on order.

Honestly the 5/8" is probably just fine. I'd save my pennies personally, but maybe that is just me.
The setup looks good! Get out and start driving it!
To reiterate what Chip said, that little electric water pump is only going to move so much water.
Addendum to Newtons first law:
zero vehicles on jackstands, square gets a fresh 090 and 1911, cabby gets a blower.
EZ3.6 Vanagon after that.(mounted, needs everything finished) then Creamsicle.
