That's a few third gear pulls and some driving, I did what I could considering it's 11ty billion degrees out (90º and 47% humidity) and rush hour, I think my threshold is set to low or I'm knocking, as I'm definitely retarding. I didn't get the same lurch I was getting yesterday. I did check my base timing before, but I failed to 0 out all the cells related to trims, so my base timing appears to have been off some (took it from Timing reference angle 79 to 71).

Edit: I'm going to try to get some cellphone video of my boost gauge when I hit target boost, I can't convey in words exactly what it's doing better then 'fluctuating between 13 and 15' on the gauge. The hydra would catch that kind of boost creep I'd imagine, unless something was wrong?

Well on the plus side, according to data log lab, if my entries are correct I'm making 275/253, which is a far cry from the ~200/190 I was making before. Assuming my engine doesn't blow up, of course. And Faeflora: My map has been looked at by Jeremy several times and he's checked everything and never commented on it. What do you run for those fields? Keep in mind I'm using Toyota COPs and not the LS coils like you :P

Edit: And here's the Timing and Fuel maps for those that don't have the hydra software..

Urrrgh fix your base timing THEN log.

Der_Idiot 06-03-2011 08:48 PM

I did fix it. That log is after fixing base-timing.

Edit: Old vs new timing maps:

Issue is completely removed by setting the adjustable WGA back 1/2 turn, or ~12.9psi. I think my WGA is too weak. :jerkit:

I think I figured out the WG flutter.

I was told previously (was it FM? or Begi?) that a WGA set to twice it's base setting or more would "act weird", IE: Flutter. My current WGA might be a 7psi, so when set to 14psi it "acts weird".
