Basically I am looking to leave the fueling for now and use my ms for the spark only?

Can i do this?

Can i wire it like this but without wiring the injectors on?



Thanks,

 

I am sure you have your reasons why so I wont ask why.
I would think the issue would be getting them both to read the cas and injector fuel and make spark at the right time. The stock ecu will throw a cel prob since it cant see the igntitor.

 

Hi, well I did have a reason but now realised that I may as well adjust fuel as well. Lol
