Default Coolant reroute, smaller coolant lines.

What did you guys do with the line going to the mixing manifold and the line going to the idle thermo thingy?

The one on the mixing manifold is the coolant coming from the turbo. The one that fed the coolant to the intake now feeds coolant to the turbo.

Connect them together or block them off. The intake manifold doesn't necessarily need coolant flowing through it but you might as well since the plumbing is already there.

I'd just run a hose between them. That's what I plan to do when I do my reroute.

Delete it all, put caps on the mixing manifold and on the head outlet port. Megasquirt takes place of that air valve, full cold control over the idle valve was a novel task too complicated for a 1.6 ecu.

You can just leave the air valve hanging off the intake manifold, but if it ever heatsoaks on a long drive your idle might go to pot. I put some sort of tape between the valve and intake manifold ports till I made a proper blockoff plate and never had any problems.

Awesome. If I had good idle on my ms3x before the reroute I shouldn't have to change anything correct?

Depends on if your idle valve even worked right before you did the tuning.

That valve basically adds idle duty percentage when the coolant is cold, as it heats up it will close the air bypass valve. If you remove coolant without closing it off (the tape) it will always be open and the idle might be fast.

If you tune it always open (removed coolant, didn't block ports) the wax thermostat in the piece can/will open and cut idle air, possibly more than the closed loop parameters can compensate for. Something to look out for, for sure.

So looks like I'll be making a block off plate soon. Thanks for the help.
