EFI Connection gives you the sensors and such, but you'd still need to supply the PCM, wiring harnesses, coils, brackets, etc.
And if you have a digital dash you'd have to figure out the fun of making them work together.
Or I suppose you could get really creative and build an interpreter to convert the 24x signal into the opti's high-res and low-res signals, then feed those into both the $EE PCM and spfautsch's DIY coil controller.
