Is there any way to adjust injector angle in the EMU ? I see only a phase to ignition event
and I'm trying to operate sequential fuel and wasted spark so I guess only a choice of 180 degree adjustment

You can use also ignition angle delay. However it is fixed in the full RPM range.

I didn't see that but i did find "Injector offset" in the Injector phase box- does this retard or advance the injection event from base angle ?

Also question about squirt twice per cycle -
With wasted spark set up and only two ignition channels used then the injectors will fire twice per 720 cycle so how does the checkbox "squirt twice per cycle" figure into this.

and
Is it possible to wire two ECU ignition channels into one channel on the coil pack ?

Thanks

Injection events are always one per cycle (720). You need to select squirt twice to get it twice per cycle.

For ignition outputs you can pair it but I can't see the any reason to do it

Injection offset delays injection start

Basically I want full control over 4 injectors in conjunction with a cam sync and a 36-1 crank wheel and wasted spark ignition.
I can do this on other ECU's but the only way I can see how to do it on the EMU is by wiring two outputs to one coil channel
then each injector can have it's own separate ignition event.I'd prefer to do this in software
If you look at the lower box inj 1 and 4 fire with ign 1 which fires twice per 720 degree so therefore the injectors fire twice per cycle regardless of checkbox. That's how I see it Maybe without the checkbox the program alternates between 1 and 4 injectors each time ign 1 event occurs ?

You can pair your coils on different output.

For ignition output you can select 1+2, 1+4, 2+3 and so on.

However if you have separate coils and cam sync why not to make ignition and fuel sequentially ? That put less thermal stress to the coils.

I think I figured out how to do it using all four ign events- the example in the help section was confusing me as it only uses 2 events.
Using the cam sync first ign event is number one correct ?
