Hi guys I'm having this problem and I want to know if you guys can help me. I've a turboed ralli 2006 and I recently have installed a megasquirt ecu to control the fuel and timing.When the car is in idle, I look in the computer to check the coolant temperature and it goes more than 210 degrees and the top hose of the radiator starts to leak coolant. I've changed the head gasket and fix the engine head, put the fans directy to the battery , changed the thermostat and the problem still exists.Please if you guys know something tell me. thanks

 

The car is running solid I'm right now at 11.5lbs 336whp but after the megasquirt setup I'm having that problem. I'm not sure if the spark timing can affect this.

 

Yes, timing can affect this but the cooling system in the car is more than adequate so I'd be looking at other places. At 11.5 psi it's possible that you're leaking some of that past the headgasket. Did you put in ARP head studs?

Yes I have ARP studs

 

Hi again; I have already solved the problem by flushing the coolant 10 minutes. The car is running solid solid right now and looking to get more boost.
