I understand the need to accurately model opening and closing effects of injectors, and that they change with battery voltage.
There are 4 parameters to specify. As far as I understand they work as follows: |

Very out of date! </code> |

The first 2 seem reasonably easy:
injopen is the time it takes at 14v from applying voltage to the injectors to them STARTING to open. battfac is a linear correction to injopen such that injopen is increased by battfac at 7v and reduced by battfac at 19v. With the transient diode mod, I have these both set to zero. The second pair are a little more interesting, since they deal with injocfuel is the time it takes for an injector to open minus the time it takes to close at 7 volts. injrampup_battfac is a scaling factor applied to injocfuel as battery volts rise from 7v to 19v. Q1 How exactly does injrampup_battfac affect injocfuel? Is it a multiply scaling or an addition? Q2 Am I correct with how injocfuel works? |
