Thanks! The PCM uses the EOT to help determine the injection timing. Cold oil has more advanced timing. Warm oil has less advanced timing. The EOT sensor is connected with two wires. Either wire can be cut and spliced with a resistor. The values that have been tried are: (0.5k 1k 1.5k and 4.1k). The 4.1k ohm has the most effect on advancing injection timing. When this resistor is wired in series with the EOT, the PCM is fooled into thinking that the engine oil temperature is lower than actual. Lower engine oil temperature causes an advance in timing. This is out of steve bazs site. Other than this and the 10k mod what should I do next to my truck?
