no, base timing is set to zero with a timing light and the TPS
disconnected.  That way the ecu (don't forget, digital projection) can
vary the timing from zero up to around 40 degrees.  I have verified this
with my timing light and much thought.  I can then change the entire
range of spark advance on my laptop.
