[Gmecm] Power/torque curves

[Robin Handley]

Anybody interested in power/torque curves for a weedy little European
engine? :-)

Standard GM/Vauxhall C20XE (2L L4) running DCOE 40s with 36mm chokes and
$58/Sunbird controlled
ignition:

Compared to the last evolution of the 1700cc L4 Ford Crossflow that
preceeded it (running same carbs, but 34mm chokes) and $8D/ANHT controlled
ignition (with too much advance at the top end, I later discovered...):

Thoughts? Looks clear to me that the 36s are strangling the XE at the top
end - which EFi should cure...
