I'm sure between the manufacturers, the police, and the legislators, this will be covered up fairly quickly. There must be some way to demonstrate the accuracy of an analyzer that will be acceptable in court.

Sure Steve, some legislatures are moving that way but it remains to be seen if they can do it in a manner that will hold up to a constitutional challenge.
Also there is another argument:

FDLE officials say that even if the state had access to the source code it would not necessary to test the validity of the breath results. Laura Barfield, alcohol testing program manager at FDLE, said each of the 408 Intoxilyzer 5000s used in Florida — soon to be replaced by the 8000 model — are regularly run through painstaking tests at the state and local levels.
