The engine:
Hello! I install V3 onto an engine like this, that a bmw E30 body I am building. I checked it that the engine works similarly, than the 6 cylinder ones engines, but the right, and the pistons are not on left side simultaneously high. 60-2 vr are primer triggers on the crankshaft.Does somebody have an experience with an engine like this?

Are you saying that the pistons are not TDC in pairs for this engine.
If they are then you can run the 60-2 trigger wheel and run 6 ignition outputs to wasted spark coils so to trigger the appropriate pairs. Injectors could be wires similarly.
Then you shouldn´t have any issues tuning the engine.

Yeah! When it is the left side, 1 and 6 pistons tdc, there is not tdc on the right side then one of the pistons. 1-1 distributor is on both sides, and 1-1 coil. I check how many deg is an offset is between the two sides.

As long as there is a pair at TDC on each bank it doesn´t really matter. As that´s what´s important to get correct ignition timing on all cylinders.
I think it would be ideal if you create a 360deg chart that shows what pistons are together at TDC, and with that chart is a picture of how you have numbered the cylinders.

This is a even fire engine, it only uses 2 sets of trigger sensors from factory because of the 2 ECU's, You can use 2 distributors with VEMS and wire injectors in pairs with the same trigger sensors
each bank is 60 degrees apart (360 / 60 degrees)
trigger settings will be:
Rising
Multitooth
N-2
Normal
tdc after the trigger: 60
number of teeth on wheel: 58
first trigger tooth: 4
next trigger tooth: 10
angular width of tooth: 6
filtering and advanced filtering will be disabled
Secondary Trigger: Disabled
Referece tooth table:
050
40
30
20
10
You might have to adjust your TDC after trigger and first trigger tooth
Ignition outputs will be assigned with each distributor alternating.
I'm not sure about the firing order so you will have to figure injector wiring out yourself

Thank you Emil! I am ready with the building in slowly, then what prepare new wiring to the engine!
