What does everyone think about this as an initial spark map?
This is a 1600cc 4AGZE big port with 8.5:1 compression, forged (stock) internals, t25 making around 15PSI boost on the best pump gas I can find.
My boost threshold is fairly high (small displacement, medium turbo, large-ish intercooler) I don't see full boost until about 3600-3700 rpm, so any of the higher boost/lower rpm values are irrelevant
I just want to find a good base map that I can start tuning on the road from, and when I've got it at the 75% mark I plan to bring it to the dyno so I can safely dial in all the high load/high boost areas. I built this from some interpolation and extrapolation of the suggested map in the megamanual.
