Suzuki H25A engine with monsoon


Recommended Posts

Hello,  I’m wiring link g4+ monsoon to suzuki h25a v6 engine with wasted spark setup but I’m stuck some places and need help.

engine’s firing order is 1-6-5-4-3-2 

I check that 1-4 is at top together, 2-5 is at top together and 3 -6 at top together. So I will wire ignition coils 1-4 together, 2-5 and 3-6 together.

my question is how I should wire injectors ?

engine’s crank and cam sensor is just like nissan rb engines, it has 360 outer tooth with 6 inner toorh (each tooth goes bigger). I will attach picture of cas sensor.

Ign 1 = coil 1 & 4.

Ign 2 = coil 6 & 3.

Ign 3 = coil 5 & 2.

For the fuel, this firing order doesnt allow semi-sequential so it will have to use multipoint group. So its not going to matter how you pair them up - just wire them in pairs, any two injectors to any drive.

Yes and if you have a G4+ the widest slot setting will likely be 24deg.  In G4X there is no widest slot setting needed for the standard Nissan 360opto mode.

yeah its a g4x

nissan 360 otpo reads rpm correct :)

roughly -90 degrees is the trigger on the g4xstorm
