IMPORTANT NOTES:
Marked with ONE *:
MS2 ECU's can be built with up to 4 injector channels. (Anything over 2 injector channels would need high impedance injectors only.)
Marked with TWO **:
MS2 + MS3 ECU's can be built with up to 6 x 5V spark outputs, capable of 12cy wasted or up to 6cy sequential. They can also be built with up to 6 coil drivers, or you can use the 5V outputs to fire external drivers.
Marked with THREE ***:
These are optional extra's and need to be added during the build stage.

IMPORTANT NOTES:
Marked with ONE *:
This is dependant on your engine setup and how you want the ECU configured.
Marked with TWO **:
See the optional extra's list below, as these need to be added during the build work.
Marked with THREE ***:
The fuel control resolution won't actually
be down to this level due to
VE and req_fuel resolution. But the hardware is capable of this control.

Note that all the listed setups would need to
have the ECU configured and built for them specifically,
this is what I do when I build them for you.
