I have looked at a lot of programs and have seen target injector timing all over the place and rev limiters set different ways.
I have been told that the best target injector timing is 360 to get a better atomization off the valve at idle and make sure it is in early enough to completely burn. What is yours set at and for what reasons?
I have seen programs that have the ignition cut off before the the fuel and others that the ignition cuts off after the fuel and I wonder what the factory sets it at. Turning the fuel off first would make sure there is no unburned fuel left in the cylinder when it relights and the other way would make sure that the cylinder doesn't go lean and possibly have fuel in it to relight better.
It seems that different tuners have different ideas about this and I would really like to hear what the rest of the story from everyone is? It's about making the engine live for a long time to me and not about every little horspower and running on the ragged edge.
So let the debating begin......
