Hey Guys,
Im working on tuning a project car of mine, It runs a standalone engine management system that requires you to edit all the variables about the engine.
I'm struggling to find some reliable data about Ignition Timing at 1500RPM under light load (-24 to -16 in-Hg). I know each engine is diffident and will run various numbers but any input will help, Ive seen people who programmed values as low as 16 Deg timing, and some as high as 38 deg.
I think scan gauge lets you monitor spark advance so if anyone can recall what their car runs at 1500 rpm + light loads it would really help out. Logically it would make sense that too much timing will reduce efficiency as it builds excess pressure during compression, even if not at the point of audible pining
Who says you cant have power and an efficent engine, 1973 datsun 240z w/ Toyota 2.5L 1jz-gte, really tall gears
300hp, 30 MPG goal
