Not true because and engine builder knows that every motor will have a "hot" cylinder and 9 times out of 10 this is the only cylinder you need to monitor with an EGT. The rest will be cooler 9 times out of 10.
As for you original question, you are running the most boost possible on a stock ECU in a AEB motor. The fuel just isn't there and the ECU knows better even tho it sounds like you don't. Go ahead and run what ever fuking boost you want these guys tried to help and it would seem it's falling on deff ears so do what ever you want. I find it hard to believe that a big shot motor guru like your self cant even afford a basic chip, but to each his own.....

This thread is stupid.
The ECU in your car is smart. It is detecting a problem and entering limp mode to prevent serious damage. Maybe your plugs look fine because the ECU saved you. If it were not for limp mode, I would bet that your plugs would look different. The fact is that the plugs will indicate damage after it has occured. The ECU will recognize the potential for damage and act to prevent it.
If you want to bypass the saftey measures that are built into the ECU, then buy a standalone engine management system. Then you can do whatever you want to your engine.
But reading your other posts, you cant afford standalone or a chip. You might be able to do the diode mod to your car to cheaply and safely increase the boost but im not sure what engines the mod works on.

Ya I read about the diode mod and cant do it.
This thread is kinda stupid. Me labeling it "boosting in the cold" is kinda dumb.
The point for this thread was for info about the ecu. You say the ecu is smart, I say its to smart. I understand the ecu is saving my *** when I had it set at 16psi. But as of right now its set at 12psi with no problems. It will cut once in a great while, the plugs look fine, so there not a problem. Basically I'm looking for the specs of the ecu. can I swap ecus?
I'm not rich so money doesn't just come to me. I have 2 kids 2 dogs a house and another kid on the way. so money is tight.

Yes, some will say that these ECUs are "too smart."
Swapping an apple for an apple wont get you an orange. Like I said, you could go standalone which is expensive and time consuming but provides freedom and allows you to adjust to any future mods.
Or you can save up a few hundred bucks for a chip. Its the best bang for your buck and will retain the daily driver nature of the car.
Also, understand that people with experience with these cars are giving you honest advice. There is no reason to become confrontational.
