Hi all,

My name is Filipe and I have this toy, a Datsun 120Y-VAN:

I'm a DIY guy that and because of that, this Datsun have already a Megasquirt2 controlling ignition only, it has a wasted spark setup and the distributor was changed to read the engine position optically:
Image

With this, I have tuned the ignition map from 50hp to 96hp:

Since that, my carburettor started leaking because of the old age, I have bought a new one from China and it was a bad idea, the engine or, is lean at high rpm or rich at idle with hesitation during acceleration:
Image

So I have two ideas, first EFI the engine and turbocharging, and this is where the RusEFI enters the project, I'm making a microRusEFI to replace the MS2.
I'm designing in fusion 360 the intake and doing some test print on a spare engine:

I need some suggestions on the ignitor part, on the MS2 I have inside 2 ignitors, but microRusEFI only supports external ignitors, is there 2 channels ignitor modules to be mounted on the engine bay?

Subaru EJ20G (impreza <1996) ignitor is known to work with MRE.
But you can find something less old.

Some Updates:

Received the PCB's and assembled the components:

Programmed the firmware and started to mess with tunerstudio.
No photos, but started to make the wiring to use a BMW eletronic throttlebody and pedal.

Going to replace the Coil with one with integrated ignitor, seams simpler/cleaner than use an external ignitor, for reference the part is 032905106B.
This is the current coil setup:
