cont. work on fuel injection controls; selected locations and cut holes in firewall for throttle and mixture penetrations, mocked up bracket location. Amazed that the cables supplied by vans are actually going to fit given everything else about the installation is custom. Finalized mixture linkage, installed eyeball on firewall, hardware on FI servo. Mixture control is perfect: smooth friction-free operation with servo linkage bottoming just before knob is fully in. Finish throttle tomorrow!
