Hi Guys,
I have a VE SS with an L77 in her. I feel like I'm having a problem with timing. I'm running a max about 16-17 timing advance at WOT. Now, even with that timing, I still get about 3 degrees of knock every now and again which I find unusual because it isn't consistant at all. I don't have my WB hooked up yet to do VE table but when I had it on the dyno AFR was around 12.4 the whole run which I have on the PE table. With that timing it made around 265kw (I have an OTR, Walkinshaw full exhaust and extractors). I've been reading they're happy around 20ish degrees but I can't seem to hit that at all with 98, E85 can hit about 21 degrees. Can any inlighten me on this? Attached is tune.
Cheers
