Here is example how to set inline 5cyle engine only run on 60-2 sensor(vr).
Injector 1=vems inj0
Injector 5=vems inj4
COP 1=vems ign0
COP 5=vems ign4
Firing order is:1-2-4-5-3
So you need to fire 5 time per crank rotation, so you get wasted spark but on one cyl(COP).
For volvo t5 you need to set:
primary trigger rissing
trigger toth: 5
next toth:12 (60/5)
h1 table=0 48 36 24 12
ign output=ign0 ign3 ign2 ign1 ign4
Becouse you have twice more ign events, you need to put double less constant for rpm, so 1200
and you need to put divider 2 on injectors.
Here is config( firmware 1.1.47v2). That config isn't maped so don't use VE and spark table.
