WoodsWagon Posted April 11, 2005 Share Posted April 11, 2005 how tolerant is the spfi ignition of over advanced base timing? I cheked my car again. and its at about 22 degrees btdc. Would that affect drivability that much? Quote Link to comment Share on other sites More sharing options...
erik litchy Posted April 11, 2005 Share Posted April 11, 2005 last i checked that was what mine was at. no ping or anything. Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted April 11, 2005 Share Posted April 11, 2005 stock is 20-degrees BTDC - if you don't notice driveability issues (ie pinging/knocking), I would not worry about it! Quote Link to comment Share on other sites More sharing options...
Snowman Posted April 11, 2005 Share Posted April 11, 2005 A small amount of advance should help with drivability if it does anything. Regardless, you might try playing with it just to see what happens. What problems are you having? Quote Link to comment Share on other sites More sharing options...
KStretch55 Posted April 11, 2005 Share Posted April 11, 2005 I need to make sure I'm thinking correctly, so if I'm not please straighten me out. I have mine set at 18 BTDC, because I have a ping and am trying to minimize it. As I understand it that means my timing is 2 degrees "advanced" from manufacturers recommendation, correct? If I set it at 22 BTDC it would be 2 degrees "retarded" from mfrs recommendation and probably make the ping worse, correct? Quote Link to comment Share on other sites More sharing options...
KStretch55 Posted April 11, 2005 Share Posted April 11, 2005 Oops! I have that backwards don't I. So, I've retarded my timing and I really want to go to 22 BTDC. I realized I was looking at it as if 20 was TDC. Quote Link to comment Share on other sites More sharing options...
