I've always had thoughts of finding ways to enrichen the fuel circuit without the use of a tuner or chip or whatever else would be required to alter the fuel curve in a system such as EEC-IV like mine, always thought it would be cool to mount an injector in the plenum and tie in to the fuel rail then use a real simple adjustable injector driver along with a wide-band 02 sensor and be able to alter the fuel curve according to engine load, am sure this is not new idea but is there anything out there that comes close and maybe i could adapt or am i just going to have to build it..
I do have future mods planned that would necessitate the need for a richer mixture so this is where the need for the question arises from ..

 

If you have a MAF, it should adapt to most mods except injector size change. I can't remember if 92 has MAF or not.

 

Nope, sorry, don't have MAF, still need ideas..

 

Got it figured out, found plans for a single-channel low impedance frequency adjustable injector driver, perfect for my application and about $20 in parts, groovy..

 

Sounds like a plan. You will need a wide band O2 sensor to monitor the a/f ratio.
