That's why I choose them over Motec for my own car. I've experience with
both systems (T6 & M48) and the Pectel is clearly easier to use while
offering more functions with more control, such as all PID parameters for
closed-loop things. They don't release new software very often, but their
stuff is very reliable and stable.

Yes it's easy to do that sort of things when you have a UEGO. To get a nice
flat transition between one and two banks will require a little bit of work,
though. You'll have to record the injection time computation parameters and
the lambda to see exactly what's going on during the change (I've logged the
relevant channels at 100Hz), then tweak the bank split parameters until the
transition from one to two injectors is perfectly smooth. At the end it will
be impossible to notice when the second bank turns on or off.
