I do however need to come up with a way of advancing the timing when the engine is at around 80C. Anybody have any ideas? The one that I have come up with is to move the vacuum line the feeds the vacuum signal to the EZL to a different source, one that still maintains a little vacuum even when under WOT conditions. We used to call such a vacuum source a ported vacuum source vs. a manifold vacuum source. (But I may have that backwards though.) This would fool the EZL into thinking that the engine is under a semi part throttle condition and thus is in need of more ignition lead. Obviously, I would need to proceed with this plan slowly, gingerly, and carefully and it would have to be just a little vacuum being supplied, not a lot cause we are only after a little more ignition advance, not a lot. I'll test and monitor the different vacuum ports on the engine with my vacuum gauge under varying conditions to see which port will serve this goal best. I'm thinking the one that sucks the fuel vapors out of the charcoal canister may be a front runner for this job.

Anybody have any thoughts on any of this? There's an older Nissan Maxima that runs consistent 15.9s (my 15.9s are NOT consistent) at the track that I want to be able to spank!
