Transient tuning: Where to start? Histograph ?
I haven't found any methods on where to start my transient settings. Surly the stock curve for a 2006 zr1/base/z06, which has zero differentiation between KPA levels, just IVT columns is not the best starting point.
How does one figure out a starting point? Any histograph ideas? xls math?
I have id1300x2's, base pressure of 62 (at no vacuum on the regulator).
25 added to injection timing. 232/234 cam
I halfed the transient tables and things are smoother, less violent, but its still a shit show in first gear.
My main issue is surge under 2000. I can get the car to hold steady for a bit then it just suddenly start surging. It does lean tip in a bit when making shifts or a fairly drastic throttle change on the highway.
