I just installed VCMuzzler a week or two ago, but it's a resistor inline with a temp sensor on the one head, right under the plastic cover. Very simple to do. Makes OBD-II think the engine is around 159-164F.
When the OBD-II thinks the engine is running around 159-164F is it increasing the fuel mix a bit, making the engine run a little richer? Or is it running the same fuel mix as it would be when the engine is running at its normal operating temps? Thanks!
