Hi,
Of course you are right! Oops.. You guys don't let a thing slip (which is good!)Didn't catch that one - fingers faster than Brain... again!
But, the DME
does retard the Spark, that is, produces it
Later in the Engine Cycle. It does this so some Fuel remains unburned and consequently, the Pressures and Temperature in the Combustion Chamber are lowered, raising the Knock Threshold.
Happy Motoring!... Jim'99
