The truck is a 2000 Silverado
with a 212/212 112 cam
Heads shaved .020
Otherwise stock
Well I realized I was threadjacking so I figured I would start my own. I can't seem to figure out what is going on with my truck at startup. It seems to only have a problem at cold startup and when put into gear when still cold. I just installed a new cam and trying to get my Base Running inline. I have already tuned the VE table and MAF, and played with timing as well as idle timing and idle AFR. What happens is the truck will pull timing at idle when cold. I have logged as much as 30 degrees pulled. It does not knock, or throw a DTC. The timing retard is also TQ MGMT Retard which is really throwing me for a loop. I have zeroed out and maxed out a couple TQ MGMT tables and nothing changed. I finally 0'd the Spark Retard Vs. Torque Reduction, and it still seemed to idle extremely bad, and still was pulling timing but not as much. I'm wondering if I am missing something basic, or is there a table lurking somewhere that I am not able to tune. The first log is without the Spark Retard 0'd out. The Log labeled weird is the Spark Retard 0'd. Thanks a lot
