Reading 3.2L ECM for knock retard
Does anyone know how I can get a reading of the 3.2L ECM for knock retard and/or knock counts? I want to find out if the ECM is retarding the ignition timing.
I brought this question to my dealer and they looked at me like I was from Mars. I don't have any trouble codes, I just want to try some different gas to find out how much, if any, the spark is advanced or retarded.
Alternatively, if anyone knows where I can find the spark tables for the 3.2L, that would probably be helpful as well. Many of the tuning sites do not seem to provide support for the 3.2L.
