Coil assignment

EMU PRO
1

Hi
question about coil and injector assignment, for me it was natural to set it up in firing order 1342 but I have now looked in the forum at the different project maps and can see that there are several that are set up for 1to1-- 2 to 2-- 3 to 3 – 4 to 4, can’t find anything about it in the manual

It depends how you’ve wired it.
The assignment allows you to change the outputs around (like a patch bay) if you made a wiring error.
Sticking with cyl 1 = ign 1 etc is the simplest and the firing order under Engine parameters does the rest.

Ignore the assignment under trailing spark unless its on a Rotary engine

FYI, trialing sparks are also working for 4-stroke and 2-stroke engines from firmware 115.0

Hi,
I guess you are coming from setting up EMU Black/Classic?
We changed the assignment method in PRO to make it more straightforward.

You can, of course, achieve the same thing in multiple ways, but the basic method is as follows:

  1. Wiring is direct - output 1 to cylinder 1, output 2 to cylinder 2, and so on.
  2. Assignment reflects the wiring - output 1 to cylinder 1, output 2 to cylinder 2, and so on.
  3. Setting the firing order in the “Engine / Cylinders” section.

P.S.
The trailing spark is used for rotary or twin-spark engines. Your assignment of trailing spark doesn’t make sense, so if you don’t have one of the systems mentioned before, don’t assign trailing spark outputs.

Thanks for the nice explanation :grinning:

This is good to know.

And I didn’t choose my words carefully enough there. “don’t assign when not using” should have been how I stated that lol
