Convert to wasted spark

[AlanK]

Gday,

I have a 1989 Galant, with a 4G63 SOHC.

This engine has a distributor, which may need replacing due to wear.

I have a coil pack on hand, from a 4 cylinder hyundai excel.

I would like to replace the distributor with wasted spark ignition, using the above coil pack.

How hard is it to fit the appropriate sensors to the engine? Can the stock ECU drive this set up? The ECU currently drives the single coil, but does not seem to have enough wires to drive a dual coil set up.

Thank you for your assistance.

Cheers,
Alan.

you would have to get an ecu that matches a car with waste spark as well as get the harness and cam sensor

A SOHC 4G63?!?!?!

I don't think the cam shaft has the 'slit' at the end, which is shown in the workshop manual for the CAS on the DOHC.

I will probably just replace the distributor for now, and possibly investigate upgrading the ignition at a later date. I don't expect many major benefits, but I am interested in how this can be done.

Is there any difference between the ECUs? Can I just plug in the CAS?

Unfortunately the disc in the distributor appears to have a different number of slots/vanes to the CAS, and probably could not be used with the stock ECU. MSnS Extra Ignition Hardware Manual

The ECUs are completely different. Perhaps you should just swap to a DOHC head and get DIS as part of the deal. You can source what you need from a 1G NT 2.0L DSM but you will need to change the harness because of the ECU differences.

Still it's going to be a bunch of work for for little difference in actual performance.
