not impossible after much work. I wish you much success.
But as for reliability lets do a parts count; 1 cap, 1 rotor, pickup coil for distributor position function (failed on my 86 900S)[works by harnessing engine rotation], 5 high voltage wire leads, 1 CDI to pump the coil (several internal parts ~ 7)
versus
1 Crank Pos. Sensor, 1 controller to read the cps and send out the operational pulses to syncronize the DI's firing, 4 oil filled coil transformers (source of most failures due to loss of coolant oil causing thermal runup damaging the coil and sucking too much current from its control circuitry giving component failure in the D.I.)
For that smooth running engine a well kept Kettering Ignition system still functions and has a low parts count. The D.I. is a wonderfull device with the knock sensing impedence reading feedback going to the controller and the clean em if you gotem plug cleaning firing cycle of the just killed engine, but when the chain has 100's of more times a parts count each one not just a redundant backup system part then there is little reliability. Thats why aircraft internal combustion engines use dual magneto spark systems, it gets you home. If you want to best the original design do a dual plug/cylinder, dual DI system, with feed back to a condition display which warns of one of them failing / seek repairs asap. And make the modules single or dual cylinder design which can fit in anywhere in between the cam shaft humps so the repair cost can be lowered because the new controller should say which one is toast (very possible today)
I wish it were an option, cause I would pay for the redundancy. Thats where SAAB could smoke the other engineering houses along with the variable compression engine tried a few years ago.
Sorry for the length but if we dream lets dream to the max. And if elected a chicken in every pot! Ooops, forgot my lithium again, darn. Saturday night humor, but what do you guys think of a dual DI'd system ???
