Inquire about

After reading the car on Dyno appeared in the screen 11.8 now is a rich proportion

The injector system is 14.7! Ie 14 percent of the air + 7 of the fuel. The lower ratio is the rich ratio and the higher ratio is considered a small proportion!

Now the car is adjusted to the injection system divided by 11.8 / 14.7 = 0.802

Another question

What is the number to be divided into 14.7or12.5

What is the universally recognized fixed number?


sorry, it's a bit hard to understand your English.

Can you rephrase the question?
