Air Temperature Sensor?

That picture/diagram is crazy looking on EF 11. Its cool but confusing a little bit.

EF10 has the picture diagram of the air temp sensor enrichment. It's a simple line graph with one line. The other one is the total enrichment of the system and is more confusing.

Argneist, let's say your air temp sensor is off, so that it reads 68F when the temp is really 75F. That means your ECU will stop enriching the mix for temps of 75F and above. At some temperature point, the air temp sensor will tell the ECU, correctly or incorrectly, that the temp is 68F. That's where the ECU will stop enriching for air temperature. (It may still apply enrichments for other factors like coolant temp.)

Eric, I had forgotten about those line graphs. Eyeballing the upper graph on EF10, it would appear that my fuel output was about 75% of what it should have been. When I boosted it by 33%, my mix was correct. I guess that coincides roughly with the experiments I had been doing with fuel pressure.
