ECU Details
This is where the electrons meet the road. Even though I have spent years on this, I have to make it clear that I don't know everything about the ECU operation. In fact, I know maybe 25% of everything. But nonetheless, there is some interesting stuff to be shared here. Once again, the information in here is based on what I think is happening in the firmware. I may change my mind on this stuff as I learn more.
The general picture can be found here. In contrast, this section is meant to get into some pretty low-level detail regarding the firmware operation.
- ECU Table theory: How the ECU converts its measured inputs into useful outputs
- ECU Alpha/N tables: Converting engine RPM and throttle position into fuel and spark events
It will be worth it in the end.
