Huge gurgled happily, sounding much like they
were saying:

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

Yes, they do. MS is very low-tech by modern standards. I know nothing
about the Omex system.

Besides, coolant temp sensors'd normally be used for the cold-start
enrichment.
