Okay guys maybe someone on here can help me. I'm very new when it comes to ecu and how they work and all that. So my question is is there any schematic out there that show you which each component does and controls inside the ecu. I'm not talking ab pinout diagrams and stuff like that. I'm talking ab for example, what does R26 control or what does Q39 control. I'm talking ab the resistors, capacitors, jumpers and all that. I'd love to know what they all control that way when I look at a board and say hey ic18 is fried so that means that must be vtec solenoid and so on. Maybe some of you will understand what I'm asking g and can help not just m but alot of other ppl as well.

Here is P28 scematics (it can be found in this forum too)
