7.7 Fuel injectors deadtime
All fuel injectors, as they are electromechanical valves, have an opening
already received an opening signal, but still has not started to inject fuel. This
parameter considers, as a standard value, 1.00ms for high impedance fuel injectors.
For low impedance injectors using Peak and Hold driver, set the deadtime to
0.80ms. These are general values; check this parameter with the injector
manufacturer.
7.8 Ignition Dwell
This option sets the ignition coil charging time. There is a dwell table
because the charging time varies according to the battery voltage, especially in
vehicles that do not have alternator.
Usually, the lower the voltage, the higher the dwell time has to be set.
Smart coils (coils with internal igniter) demand lower charging times. These
are general values; check this parameter with the coil manufacturer.
Dwell time. calculated by the MSD module.
7.9 Wiring harness connection table
After setting up all of the Engine Setup options, the ECU outputs are all shown on this menu. Before starting the
electrical installation, go to steps 3 and 4 on this manual, then check this menu to use it as a guide for electrical
installation.
