Shot me 3 deer!!!
So what are the benefits of this?? I don't understand the entire theory behind this.
No no , Has little to do with the ignition timing and nothing to do with open/closed loopIt has to do with ignition timing and open loop operation. Basically it's keeps the car from going into closed loop operation and gives a little more timing, but not much because the car is trying to reach that higher temp. It works similar to the warm up process.
Or at least that's the theory.
more fuel doesn't mean more hp, actually it means less!! you want to almost be running lean else you have too much fuel and less air in the cylinder and since you cannot use all the fuel and there is less air to combust, you waste gas and get less hp!I believe, if it's like most Fords, it also causes the ECU to richen up the fuel/air mixture a bit-which should add a little hp/tq. Some guys go down to 160 deg. thermostats-at least for the Escapes.
after cold start fueling has ended.
