TurboBob said:you have a stock (S) datastream chip.
To display the spark advance on your Scanmaster 2.1 you need W or Z.
W is high speed (updates O2 and Knock 3x faster than stock), but is not compatible with ordinary scantools (OTC, etc). Malfunction codes are not transmitted.
Z is a stock speed datastream, with Pulsewidth and spark advance. It will work with ordinary scantools.

Or you can swap chips back to a stocker, and key-on without starting and read the codes.
