So is TPS optional, or required? More importantly, what pin/port is it? What S12X AN is IAT? What S12X AN is CHT? What S12X AN is TPS? What S12X AN is MAP?- IAT,CHT,TPS,EGO,BRV,MAT MUST be implemented on ALL hardware designs.
- TPS is optional to connect, but highly recommended for all installs
Again, what pin/port. Your Pin assignment .ods file notes all AN's are swap able. However I notice issue 190 is newer than the .ods. What should I use for a pin assignment, as the ods appears to be out dated.ADC pins can stay as-is pin wise
Also why have you chosen that ADC stuff will be hardwired to specific ports/pins? I understand the requirement for PT to be your ignition and injection channels, until XGate stuff is better. But I don't understand why AN1 has to be AN1 and not AN2. They all use the same MUX, so the signal delays should be the same. Perhaps the issue is sourced from the crappy sample and hold, and it's tendency cross talk signals to adjacent input signals. However if that were the case, then you would have put the unused AN's between the other signals, to prevent this kind of leakage. So I don't follow why it has to stay wired this way.
