I need a answer.......
Any one can tell me: how the ecu know when to inject fuel to the chamber ?
A/F Ratio at 12.8~ 13.5 is the best ....
crank angle sensor is doing the job.... it's true???
If the answer is true ....
Then adj the crank angle sensor is not the right way to adjust ur ignition timing...why ?
When ur cam is at stock position and u advance the crank angle sensor, the sensor tell the ecu the valve already open is time to inject fuel. But in real the valve still close and the fuel only spray at the valve, not mix with air and go into the chamber....
May be it just affect at the low rev range... not much affect at the high rev range...
I still wish find out the right answer....
