- BRV connected to an appropriate divider within 1 Volt or so of the truth (for first starts, within 0.1V before any tuning goes on)
- IAT connected to a sensor mounted in a decent location with an appropriate bias resistor and a correct transfer curve in the firmware
- CHT connected to a sensor mounted in an appropriate location with an appropriate bias resistor and a correct transfer curve in the firmware
- MAP connected (via hose AND wires/traces) attached to the plenum or an appropriate balance tube setup (for ITBs or multi carbs) and a correct config pair in the firmware
- RPM is assumed to be connected or nothing would work at all.
