Don't want to resurrect this post here (although it seems I have a history of doing this) but could anybody elaborate on the difference between port injection and throttle body injection, from a code standpoint?

The MS2-extra manual seems to be quite brief on this topic: http://www.msextra.com/ms2extra/MS2-Ext ... ore_engine
Injector Port Type (InjType) is used to select the type of injectors that you are using, either throttle body (if the injectors spray above the throttle plates) or multi-port (if the injectors spray into the intake ports).
It seems perhaps the reason it exists is not to change the VOLUME of fuel injected, but rather the timing of WHEN it is injected with relation to the engine cycle to account for the time it takes for that fuel to travel down the runners and atomize.. ?

It's not actually used in the code.
