wow , josep davids (later i did know who you are but now yes). i think too, i will try to understand it. :y

I have no idea what you just said, but I like it!

Re: How does ECU control the ignition?
 

i said that i can no to explain better for you understand what i need to learn, and i will try to learn reading (or try cuz my bad english) tech articles as the wiki of PGMIF.org or so.

Re: How does ECU control the ignition?
 

Yup, it's all there. Helms is actually pretty good at explaining what each sensor does.

Ok smarty pants, how exactly does the ecu communicate with the 7U016 to produce the ignition signal. ;)

Also one thing I speculate on is that the ecu does nothing to control the actual timing sequence. If you notice the signals coming from the distributor sensors all go into the 7U016. So that makes me think that those pulses act like a clock signals and the ecu simply applies an offset so to speak that provides the ignition value. It applies to the fuel injectors firing too, but since there is an individual cylinder correction, then the ecu doesn't apply a bulk value, but instead knows which injector is firing and thus adjusts it accordingly.

oh, good explain, what is 7U016?

this case is the same in B16a ,right? i means that the ecu (or 7U016), control the ignition..
