I'm not sure the inputs and outputs are that much more complicated now than they were in the 90's. Cam/crank position sensors, knock sensors, O2, MAF, TPS, etc, on the input side. Outputs, I suspect, haven't changed that much either. Variable valve timing, running on fewer than all cylinders, etc, isn't all that new, and the other outputs (injectors, spark, and so on) haven't changed. They got by with MCUs and EEPROM maps for a long time. |
