Here's the analysis if any one wants to check it out. This was this motors first oil change, ~1500 miles on Chevron conventional 5w30. I didn't get a sample of the second change but the third one is due in a few hundred miles and I'll be sure to get a sample for Blackstone. Getting tired of its look, and the unwanted attention i get from boy racers, so I took the mudflaps and spats off. Need to make a craigslist post and see if anyone local has a trunk they'll trade me, as the wing is basically welded to this trunk. Kind of want to give the wingless look a try but don't want to bother with the third brake light.
  1. If trims are roughly the same, but positive, then you need to lower your injector scaling number.
  2. If both trims are roughly the same, but negative, then you need to raise your injector scaling number.
  3. If idle trim is more positive than cruise trim, then you need to increase the latency value.
  4. If the idle trim is less positive than the cruise trim, you need to decrease the latency value.

When increasing and decreasing latency based on these tuning tips I interpreted it as the gap between old/new in the emanage needed to get closer or farther apart. But, since I have information from DW about latency on my big injectors then MAYBE I just need to increase/decrease the old injector latency. As no one seems to truly know what the air assist injectors are. The one post that I've found with latency information on the 280's says the dead time is .4ms but that's wrong. I was getting 10 at idle and -10 at cruise. I believe TerryJr was quite successful with .7ms, when I've tried this idle trim usually skyrockets to 20-35 after an ECM reset so I don't think I ever actually ran it. Runs much gooder after actually taking it out and driving. I'll check the trims in a week and see where it stands for adjustment.

Is somebody thinking of going manual?

I tell people I drive an automatic on purpose, as I do have issues with my left hip, but the transmission is holding the car back, and I actually think it's starting to fail. Chassis has a quarter million miles on it. I'd love to find a 4.44 set! I absolutely adore the rocket ship nature of the automatic, and I'm more of a red light racer than a big runner.

I ran against a newer Aston Martin, and it couldn't get by me (I only build 9psi!), but the motor was hurt afterwards unfortunately. Compression is still in spec, but #4 is ~10
lower. It's always number 4! But aside from that the car has more power, harder pull, and the most normal consistent fuel trims than it ever has.

Regarding stock injector lag/latency time; the post I found that said they pulled info from the ECM says .4ms. TerryJR and pretty much every other person that has used an emanage ultimate says .7ms. I am using .58ms right now and my trims are -5-0.
