How do I fool my ECU?
#21
So to sum it all up, I don't really see any negative so far with my engine running around 165. Maybe something long term might show up. This next tank of gas will be around town pulling a 6x12 single axle enclosed trailer full of tools with the a/c on. I will report back with mpg for that. Next I will figure out the resistor trick to fool my ecu and see what that does. Any help on how to would be greatly appreciated!

Not trying to be a smart***, I just want to know more, so here are a few questions. Keep in mind I am not an expert so they may sound stupid...
Wouldn't there be a reason why ALL engine manufacturers design engines to run at the higher temperature?
Doesn't the catalytic converter need a high temperature to burn the byproducts efficiently?
Wouldn't the O² sensors' heating element have to work harder to maintain a correct operating temp thus shortening their life?
Isn't it true that the air-gasoline ratio burns more efficiently at a higher temperature?
Doesn't reducing the maximum coolant temperature also reduces its ability to carry off more energy?

The catalytic converter gets it's temp from exhaust gases which hasn't got any cooler.
The oxygen sensors aren't working harder because the exhaust gases aren't cooler.
Cool dense air mixed with gas makes a more volatile explosion which increases performance and exhaust gas temperature. That is why you put an intercooler on a turbo vehicle to reduce the air temp going into the engine. Hot air in is bad. Hot air out is good.
And how in the world could reducing a coolant's temperature make it less effective?

I'm still interested in this mod, but I will say that my wife's VW New Beetle had a stuck open thermostat that caused the engine to run cool. That caused the Catalytic Converter to burn out due to running rich from ECU Confusion and Adjustment. It costs $1000 in California for those.
I'm not saying your idea is bad or good, but I did run into an issue on the VW. I think if you found a happy medium, it would benefit and not hurt. What that happy medium is, I have no idea...
