im thinking about the hyundai efi system i need to know some details such as how does it work? does it need to come off the distributor for the injector pulse? does the throttle body work off cable or electronic?
As far as I know, not one person has ever completed the
Hyundai EFI swap.
Possibilities:
* Mechanical throttle cable, just a like an A12/A14. The idle speed is controlled by the ECU (just like Datsun EFI) but not the throttle opening/closing (as in new Fly-by-wire throttle systems).
* modify the manifold bolt-pattern to fit (it is very close)
* Use a sock filter -- there's enough room. Alternatively, modify the manifold throttle plate (move to other end via cut-n-shut or JB weld)
* The ECU generates the injector pulse, not the distributor -- for all EFI systems. Some systems time the injector pulses to the cam position (often called [edit:] SEFI), but this doesn't increase HP instead it is for emissions.
* When you go to the wreckers, examine the Hyundai system. Does it use a CAS wheel in the distributor? If not, just use the Mitsubishi
ECU -- get the whole Hyundai harness and ECU. But if it uses CAS wheel, search for a different year Hyundai. Or you might use a Datsun [ECU]] (which needs no special distributor) or an aftermarket
ECU. Both can control other EFI.
Mitch built a custom plenum, but I did not hear if he ever got it running.
