MSD 6302 ignitior setting

[Marc-liang]

I use aftermarket ECU " HALTECH E6K " controll the ignition system.

I use the MSD 6302 ignitor to fire the MSD-8242 for waste spark mode.

How do i set the trigger edge for MSD 6302?

Is it Rising or Falling?

What type of signal for 6302?

Charge time or Dwell time?

How many number for the time?

Hope you can provide the data.

Thank you so much.

The attachment is a traditional DIS Signal. It explains better than I can in print.

Charge time.

Once per cycle.

I only use 6302 to controll the 8242 coil.

I do not use DIS 2 ignition.

Do i set this value,also?

Thanks for quick reply.

Unfortunately, the 6302 was designed to work in conjunction with the DIS Ignitions. It will not work properly without using the MSD Ignition.

There is no way to adjust that unit.

If you can adjust the Haltech unit, you might try that.

Wish I had a better answer.

I saw the Manual of 6302 told that it can directly drive a coil.

I can set the ignition fuction of haltech for 6302 by myself.

Do I still set falling trigger , charge time 2~2.5ms for the 6302 ignitor?

Or have any other setting value for only dirve a coil without DIS box.


Thanks.

Set it for a falling trigger , charge time 2~2.5ms for the 6302 ignitor.

Having never done this before we are not absolutely sure if this will work or not.

Good luck, let us know the end result.

I set it for a falling trigger , charge time 2~2.5ms for the 6302 ignitor.

The engine can not start.

Finally I set for a charge time 3.5ms, the engine run.

But it was possible about fuel pulse setting problem, too.

Do you know the maximun charge time range of the 6302 by MSD recommend value?

Thanks.

Unfortunately, that is proprietory information and cannot be released to the public.

I can not know the limitation of 6302.

So why MSD tell customer that it can be as a coil ignitor in the user manual?

Sorry about my a lot of questions.

The 6302 was designed to be used on imprt vehicle applications where there is an ignitor embedded in the factory coil packs. Usually the signal from the factory computer is 180 degrees out of phase from what an MSD CD ignition is wanting to see. The factory signal, in a stock application, gets modified by the electronics encased in the factory coils. The PN 6302 is designed to take the factory igniter signal and create a signal that the MSD is able to detect and fire the MSD ignition. It is not meant to work independently without an MSD.

This is why we cannot wire an MSD into any foreign factory coil pack that has more than two wires wired to it. The MSD is made to go between the coil igniter/driver and the actual coil connection. Wiring to a coil with more than two wires physically touching the coils will cause damage to both the coils and the driver.

From the instruction sheet for the PN 6302, first statement.

"The MSD Dual Ignition Coil Ignitor allows for the installation of an MSD DIS-2 Series Ignition Control ....."AND"..... MSD Coils on vehicles with factory transistorized/driver style coils."

"It achieves this by inverting the logic signal from the ECU and creating a high current output to drive an inductive coil, or points input of an MSD Ignition Box."


The Haltek should fire the coils just fine without the use of the 6302.
