I think the 2 BAR sensor is the way I'm going to go - iff I can get one
cheaply - and I'm working on that (with help). :-) With the way the Sunbird
code tables are organised, I'm not sure I'll suffer too much with
resolution - and more so on ignition than injection, which is probably the
best way around.

If I go with my DIY individual TBs and fit injector bosses to my existing
DCOE inlet manifold runners, I plan to use some injectors from the engine as
it was installed in the original vehicle (which had a single throttle body
SFI system). The injectors are Bosch 280 150 427 - which an online lookup
table rates at 240cc/min (22.95 lb/hour / 173 gram/min) assumed to be at
~36PSI (2.5 BAR).
