My car may not be anywhere near the fastest, but it sure as hell is consistent....

PSmalls::DoggieStyle · 08-29-2005, 11:31 PM

I can pull 3.9-4.0 FATS and 5.3-5.5 FATS+ times in 70+F at will in my car.

Tonight, I pulled a 3.97 FATS and 5.48 FATS+ in 73F with boost spiking to ~22 psi and tapering to ~20 psi.

MAF and Timing (highest RPM MAF peak I've seen on straight K04s, less timing pull back up top as well):

Correction Factors (look at cyl6, wtf?):

02 voltages (think I should lean it out a bit more?):

I'm open to suggestions for further tweakage although I don't want to go too aggressive. I'm considering pulling back a bit more fuel and seeing how that affects things. Any other brilliant ideas?

I think new plugs are in order anyways.

with you being on 94 octane all the time you should be able to run slightly lower 02's, it's mainly the guys who have the crappy 91 who need to stick in the .87/.88 range. I've seen better results on .86ish volt's now that I found 94 to run on all the time

as for cyl 6 maybe an injector isnt seated right? possibly the lil rubber insulator from the coil pack to the plug. fouled plug? maybe the entire piston is missing? would someone steal your piston? i would def check that out.

it is nice to run consistent sub 4's. i think your setup has the most time taken to ensure this. all the little stuff you and mike have worked out all seem to work towards this. congrats on that.
