Thirty years ago 38° was the desired FE goal.I've read where some are getting better results with less.I'm currently running 12° bftdc initial timing and think it is a little bit too much.starting is not a problem .I have a Hy Fire VI which has a programable automatic start retard that I have programmed in 8° retard any thing under 500 rpm so I'm actually starting at 4°ftdc. Make that livable.
Any time you start the burning prosces before or after it's correct time it should work against the motors performance.Manufactures use little advance ( like 10 degrees distrib ==20° crank. because they don't want to spend the time and money to make a each distributer advance the correct amount at the different rpm levels.And performance will impact their liability (warranties)I haven't had my car running that much since getting it together.but I'm sure that initial should be around 8° to 10° bftdc ,starting should be around 4°bftdc and total should be 36° to 38° bftdcThat means you'd have to have a distributer that advanced 28°to 30° currently mine goes 20°
Now when would you want that timing to start coming in?How much when?
