In fact, after posting, and after some gentle prompting (thanks!), I checked
my LD Astra (4 cyl 1.6 TBI) schematic - and yes this model, and the 1.8 TBI
JD Camira uses a link between D9 and D10, so that the single TBI injector
runs in Peak and Hold (P&H) mode. These vehicles use the 1227808, which
is a 1227165 in a short case, without the SXR (8192 baud driver) chip.
