Not true. CLT, MAP, IAT and couple internal analog inputs are not those we see among 8 analog inputs captured through MCP3208 chip.
Best way find right ones is using documents supplied with ECU. If not then try to find those inputs on EC18 pins 2,3, 6, 12, 14, 15, 16.
Pins 2 and 3 might be channels 2 and 5. Pins 6 and 12 - channels 7 and 6.
16 IIRC is analog input ch0.
Pins 14 and 15 also can be internally wired to ch2 and 5 depending on version/configuration.
