yes, it's all in how you program the ECM.  You just need injectors that a=

Hello,=0D
 =0D
I have another question concerning bigger injectors with ethanol fuel. If=
 I
was to get higher flowing alcohol-specific injectors, can the injectors
still be reprogrammed to accomadate leaner fuel mixtures? For example, as
part of my project for an engineering competition, I want to add a few
modifications to the engine that will allow leaner mixtures to be used. S=
o
my question is, even if I get injectors made for ethanol fuel, can I stil=
l
modify them to allow for leaner mixtures.=0D
