hi guys I have a question.when we increased the fuel why does the ecu increase the advance ? whats its reason?unless the ecu increase it will be knock in the engine?Can you explain me ?

 

That's it's job. What do you mean you increased fuel? Be specific and give more detail.

 

for exaple suppose that plug afc.I wanna inrease the fuel amount.when I increased the ful why advance will be increased by ecu?I mean unless the advanse increase what will happen?or if the increase too much what will happen?shortly I am wondering advance's benefits and deficits?

 

Because the AFC is junk & the ECU is trying to do what it's programmed to. Increasing fuel by itself doesn't increase horsepower.
