Scott, I have enjoyed your info.
Question...does LSE believe a staggered spark timing to be beneficial for
power/economy? I was going to test this at GM but never had the
chance. My intuition said any benefit real or imagined would be hard to
measure, but as I said...I was not able to test.
"Scott said:The timing checks indicated a 3 degree retard (instead of
LSE's 5 degree recommendation)."
I'm willing to bet at a 5 deg retard you are giving up power and fuel
economy. Unless you are detonation sensitive, I would expect no more than
a 2 deg retard on a 27 deg baseline for a 10 to 1 CR motor. I
would be happy with the 3 deg shift.
