Anyway - most cars don't have an inlet air temp sensor these days -
they measure the mass of the incoming air instead via an air mass
meter rather than air flow meter plus inlet air temp.

Have installed both Megasquirt and Omex ECUs in the recent past, I can
assure you that both these systems have inlet air temperature sensors.
You need them for cold start enrichment, for one thing.

I presume it also has a coolant temperature sensor - and it's that one
which does most of the work. The air temp one just for fine tuning.

(And the Omex on
my TVR doesn't have an air mass meter, either - it does fuelling solely
on throttle position and lambda.)

Pretty crude, then?
