Piggy-back control

[Tuck]

Has anyone done any work on using a piggyback computer that would intercept
and modify things like injector pulse width and ignition timing?  I know
this is the way the PFS PowerTrain Management Computer works on the third
generation RX-7's, and I'm interested in wither designing and building a
similar system for my  car, or purchasing an off-the-shelf solution.  I
don't see any reason why a generic control system couldn't be designed
expressly for that purpose, something that would only require a different
harness to work with a different EFI computer.
