How to advance the timing?

jetuomi · 07-19-2001, 12:47 PM

with my mainly stock 94, I ran around 14* at first, and it was great, but, as summer approached, and I started using air-conditioning, and driving home (550 miles) more often, passing trucks on the highway started to cause pining, so I backed it down 2 degrees..

funny this now is that it revs faster, and feels stronger @ 12*..

my thought on this is that since you letting the piston travel that little extra bit up the cycle before firing occurs, it isn't putting as much stress on the components, and its revving better..

And, I believe our engines have knock sensors, that tell the computer to retard the timing... so, even if you're only pinging a bit, you could be losing performance.. (can anyone verify this for me??)

I don't know if this is right, or not, but, if you find 14 degrees is good for you, no ping, try 12, 12.5, it should be great !
