i need to know how many pulses does a honda accord a20a4 give per crank rev and are the pulses equally spaced?

Question

i am programming an ecu for my car so i need this urgently

Answer 1

generally, a crank sensor will have 5 triggers for a 4 cyl. engine. 2 triggers real close together tells the sensor/ ecm cyl #1; the other 3 spaced equal distances to signify the 0ther 3 cyls. cam sensor will trigger only once, to signify cyl#1, top dead center. cam sensor can fail, and engine will still run, but chk eng mil will be on. when crank sensor fails, you're walking home. this is generally how the system works, manufacturers may vary slightly, but not much. so, to answer your question; crank sensor will trigger 10 times for 2 revolutions, and cam sensor will trigger 1 time every 2 revolutions. it may seem odd that it will trigger 10 times for a 4 cyl engine, but the engine doesn't fire everytime the crank sensor triggers. it just uses some of the triggers for references.remember that it takes 2 revolutions of the crankshaft(720 degrees of motion) to complete all firing cycles.

Answer 2

Which pulses do you want to know about?
The Crank Sensor ?
The Cam Sensor ?
The TDC Sensor ?
The Fuel Injectors?
