Subject: Re: Weird timing issue by djxib on 2013/5/27 17:24:37 I've seen that too. The only things I'm aware of that would cause the actual timing to change for a given RPM are the 'closed TPS advance' (that you'll see if you lift off the throttle between shifts) or spark retard due to knock. I meant to do some research on this a while back but too many projects.. I have noticed however that at WOT the timing is exactly as described at 100KPa unless I get knock (1992). Assuming your closed TPS advance table maps to your main spark table, 14 degrees at idle sounds very low for your cam, you could try different degrees of advance to get the best vacuum at idle. I run about 30 degrees on mine. Good luck! |
