Re: Thermostat talk: Fooling the PT CPU into thinking cool....
These cars have an intake air temp sensor right? IF they do(I really have no honest to god idea if they do or not) try raising the resistance in the signal wire of the IAT back to the PCM. This also works the same if the car has no IAT, but has a battery temp sensor. From what I understand a battery temp sensor functions the same as the IAT if one does not exist. It helps a little with the acceleration on my Ram without throwing codes, or risking overheating. On my Ram, a 1/4 w 4.7k ohm resistor fools the computer into thinking the actual air charge is 15 - 20 degrees cooler than actual temp, fooling the PCM into throwing a little more fuel in.
