Engine Mods that Do and Don't Work

[bmpcamry09]

I've done some real-time monitoring, but so far in somewhat limited circumstances. I get absolutely 0 timing pull during my hilly commute at ambient temps of 70 degrees or lower. I occasionally see a half to one and a half degrees when temps are a little warmer. I get 0 under light acceleration on the freeway. I'll soon see how the Summer and longer trips go.

You’re lucky if you’ve got 87 in your 2.0 and no knock. What about wide open throttle? Which knock retard are you watching? There are 3, short term, long term, and fuel. Short term and fuel are the ones for what is currently happening. Long term is the learned value applied consistently.

I was making more reference to actual spark advance. As soon as throttle is tipped in I was seeing negative spark timing itself.

I watch LT, ST, fuel and total. I've seen 1.5° LT blips when total held at 0.

When I tried WOT (uphill) I got 0 total, but funny enough, all the sudden I caught up to a couple police vehicles dealing with a pedestrian on the middle shoulder which slowed everyone down, and I saw a few degrees for a couple seconds when I was forced to abruptly get off the throttle.
