John, I don't know about third Gen,
but assuming its the same as 2nd gen - if you remove the top thermostat housing,
the 1/2" dia hole can be seen by looking straight down into the part remaining
on the engine , the hole is on the bottom of that part of the
housing. Also your thermostat should have a protrustion that is mean to
plug the hole when the thermostat is open.

Great!

John, I
would tune using the air/fuel indicator. I would establish an rpm say
starting at 2000 and initially go up in 500 rpm stages. Let the engine
stabilze at an rpm and then check the air/fuel indicator. Then adjust the
manual mixture control (right knob) until you have the LED where you want
it. I would initially shoot for the middle of the LED range or perhaps one
higher. If the engine appears to be running like you desire, then having
selected mode 1, turn the program mixture knob (left knob) until it matches the
phyiscal orientation of the knob on the manual mixture. Then press the
program button once. That should set that mixture for that rpm and
manifold pressure. Then move up 500 rpm and repeat. That should get
you in the ball park.
I suspect that with the 550 ccm
injectors the default setting that the EC2 comes with might be a bit on the rich
side.
Glad to hear you now have cooling and
confirmed you have oil. I doubt you have damaged the turbo.
