Hi!

I have a Black ECU with a defective ignition output #1. I’m running this on a 6-cylinder engine with one ignition output per coil. Is it possible to configure it as wasted spark using only 3 outputs and logic coils? If so, how do I set this up in the software/client?

Thanks,  
Henrik

Henrik,

you have to select the same ouput for event 1 and event 4  
same output for event 2 and 5  
same output for event 3 and 6

Normal firing order for a inline 6 cil is 1-5-3-6-2-4  
So wire cil 1 and 6 together  
2 and 5  
3 and 4

Hi and thanks for answering.

Will this setup in the client be correct ?

According to the post above, your firing order is correct, but you’ve assigned the outputs incorrectly. You’ll want to match it to what the previous replier said.

That looks right to me. At least according to the previous reply. I haven’t ever setup a 6 cyl. But that matches how I have my 4 cyl wired.

Just want to inform that this setup is working just fine.
