Timing Terminology
A quick question... I hear the phrases base timing, initial timing, and several others I believe..what exactly is the difference? Is there some math going on here? My engine, without the computer connector in, was running 18 degrees of timing previously, which is WAY too much for a motor with stock internals..think the only reason it didnt do too much, DIDNT EVEN PING!, is because I was running really rich with a bad Coolant Temp Sensor and 4 shorted injectors dumping fuel..but the point is, is that 18 degrees considered to be base timing?
I'd just like to get some of this stuff nailed down so I'll know how to convert between the different scales here...
