The #s I gave are a little aggressive but I could run those on 93 here. I've since taken .5 psi out to remove all timing adjustments but on these cars, even pulling 2 degrees and change is considered OK.[/URL]
I took a smaller step, added a little on top of the M3 adds.
M6on94 Log. No corrections, postivly incrementing timing, brings me to a few questions:
1./ Is there a generally agreed "timing advance target" at 6000rpm? Earlier posts, folks were looking for 18* at 6k, and suggesting cutting boost to retain that solid advance. Looking at my data, M1, M2, M3, M6 - all topping out around 14*
2./ In 20C/70F weather, otherwise stock on 94, how much abs boost is typically possible? Is timing correction the eventual limit, lack of advance, or something else at this octane? (I plan to stay additive for my region, unless someone provides compelling rationale to do contrary)
3./ What is the consensus on ideal boost "shape" for conservative/fun DD? Currently peaking in the 4-5k range, with taper up from pretty low at lower rpm, and smaller taper off up top. This is a 6MT 4MO, I generally shift short, excursions >5500 aren't frequent. Im a generally safe shifter, but would appreciate discussion on lower additive targets down low, vs keeping them up and adding a 1st/2nd gear redux.
Insights appreciated - thanks!
