Wolf v4 on 20B
 

Is it possible to use the v4 (not the v4plus) in a 3 rotor config?

6 injectors (3 primary, 3 staged), 6 coils... I'd think so but I'm 100% sure.
Does anyone know for sure? I've emailed Wolf.. doubt i'll get a reply.

theres a section in the injectors section of the manual, i was having this problem on my setup. if you know the ohms you can calculate if the wolf has enough juice to open them up. i was running about 8 injectors

I don´t know how do you rotor guys deal with both spark pulses for each rotor, but I guess V4 doesn´t handle 6 individual signals for either spark or fuel.

Yes, it will work, but it will only run simutaneous timing of the leading and trailing spark plugs like race cars use. If you want split timing for emissions, you will need to upgrade to the V4 Plus. The regular V4 only runs split timing on 2-rotor engines. I am not sure about the new V500. I listed all of the proven 20B split timing EMS models in the 20B FAQ.
