    dwell vs map 2 bar

    First off I am running an LQ9 at 12psi. I have dynoed with stock and increased dwell times, those showed negligible improvement. But with stock dwell at 12psi I can only run 10* timing up top. With the dwell increased to about 7ms up top I am able to run about 15* advance up top. I wasn't able to dyno at 15* because i discovered that i could increase the timing on the street. Truck definately feels faster though. I am using a 2bar tune. I want to use the dwell vs map multiplier so that I can run less dwell while cruising so that I don't overheat the coils. the map in the table maxes out at 105kpa. I am wondering what happens when I am in boost. Is this table ignored or does it reference the 105kpa column.

    I would assume it uses the 105kpa column once it goes over that.
    It doesn't have to be perfect, it just needs to be done in two weeks...
