Here is Ed's latest design on the right.
This is an O2 sensor display for mixture adjustment
and a digital flow meter that interfaces with Tracy's EFI 
computer.

BTW both Tracy and Ed use switches to select the primary or
secondary injectors or both. This in conjunction the EGT read out 
does wonders when it comes time to trouble shoot injector problems.
Also good for pre flight just like dual ignition.

Bill Freeman and I had a discussion on the advantages
of electronic injectors over mechanical injectors awhile ago and we
decided at the time there appeared to be only one. Easier
starting when warm. Well here is another one.

BTW Tracy's computer has a built in limp home mode if one or more
injectors fail. Correct me guys if I am wrong. I should have
taken notes.
