This was surprisingly hard to fit into a 1 minute video!
If you have changed your injector size you will need to do this before attempting to start the engine. I see this on help forums a lot when people forget to do both steps, or can't find/don't know where to enter the data.
Shown is the Black software but the process is very similar on Classic's, parameters and tables are named the same but are all under "Injectors" on the navigation tree.
I do not recommend buy injectors that don't have deadtime data readily available. Most are just a dead time vs voltage table, but @injector_dynamics takes it a step further and has separate data for each type of ECU. Especially for Volumetric Efficiency based fuel model ECU's like the Black this information accuracy is very important.
