Got my wideband hooked up today and decided to keep to boost low to start. Well good thing I did that because it started to go 14:1, 15:1 up top after about 5000. For fuel, I am running two secondary dsm 450's. Now mind you that the injector controller that controls these injectors was on the richest setting. tHis shouldn't be as I know this is more than enough fuel to support my needs. I also have a walbro 255lph in tank pump. I know both of the injectors are firing. Do you guys suggest maybe I need an AFPR or maybe the injectors are clogged and not firing to their full potential? Maybe the fuel pump isn't fucktioning properly? I don't know.. Just looking for ideas. Thanks

 

so you're running 6 injectors on the same fuel pump? how does that injector controller work?

I think you might need a seperate pump inline for the 2 450's and this is a cavalier 2.4 engine correct?

 

what injector controller is it.. on my rebic 2 , there is another option to choose the maximum duty cycle which is inside the unit, as well as the normal boost/rpm/duty cycle options

 

Maybe..

 

rebic 3. Is that the same thing as the rebic 2? I have a duty cycle **** on the outside.
