John, I don't know = about third Gen,=20 but assuming its the same as 2nd gen - if you remove the top thermostat = housing,=20 the 1/2" dia hole can be seen by looking straight down into the part = remaining=20 on the engine , the hole is on the bottom of that part of the=20 housing. Also your thermostat should have a protrustion that is = mean to=20 plug the hole when the thermostat is open.

John, I=20 would tune using the air/fuel indicator. I would establish an rpm = say=20 starting at 2000 and initially go up in 500 rpm stages. Let the = engine=20 stabilze at an rpm and then check the air/fuel indicator. Then = adjust the=20 manual mixture control (right knob) until you have the LED where you = want=20 it. I would initially shoot for the middle of the LED range or = perhaps one=20 higher. If the engine appears to be running like you desire, then = having=20 selected mode 1, turn the program mixture knob (left knob) until it = matches the=20 phyiscal orientation of the knob on the manual mixture. Then press = the=20 program button once. That should set that mixture for that rpm and = manifold pressure. Then move up 500 rpm and repeat. That = should get=20 you in the ball park.

I suspect that with the = 550 ccm=20 injectors the default setting that the EC2 comes with might be a bit on = the rich=20 side.

Glad to hear you now = have cooling and=20 confirmed you have oil. I doubt you have damaged the = turbo.
