Head Temp Sensor Effects
Posted: Thu Apr 25, 2002 11:27 am
I just completed a pSpice simulation analysis of the head temp sensor circuit in the ECU:

The results are pretty interesting. They show that the head temp sensor's effect on mixture is fixed past temperatures of around 210 F or so (as you would expect). They also show that there are significant differences in the warm-up characteristics of the two ECU's I analyzed (037 and 052).
I'll be adding data on using ballast resistance and comparing the odd 0 280 130 017 sensor later.
