Timming LT8
from what i understand, the less the split the more power, the more the split emmissions/fuel economy gets better, right?
i was wondering on the timming issue of the LT8 that im getting from the group buy, i'm going to run the base map for a long while, but when i do upgrade the turbo, injectors, etc. i was wondering how does the lt8 control the split timming issue? and how do i tune the ignition maps? what are the best ways to tune ignition maps? because i can't really trust the tuners around here, "honda performance shops" are not so trust worthy for rotaries..

Jon's assured me that the ignition maps that will come on the unit will be conservative enough to be safe, but agressive enough to make halfway-decent power.
To be honest, ignition tuning is the biggest "trade secret" of rotary tuners. You're right to a point (less split means more power) but past that point you start blowing motors. I would stick with the base maps until you can get to a reputable tuner.
If you do want to play with them yourself, however, tuning is very easy. You've got a base ignition curve (think of it as vacuum/centrifugal advance), a MAP correction (think of it as boost retard), and timing split. Just be careful!

The LT8's have a pretty good base map in them for the timing split.The only way to get it 100% right is to spend a day on the dyno.Each engine is different so there's no such thing as a "correct" timing map that will suit everyones engine.
Run with the base timing map & you will find it will be a lot closer than you think.
