Tuning is not an issue. I'm assuming I just need bigger injectors?

 

injectors, maybe a pump. tune.
done.

 

Psh, like you would know.

Area47 has my non-flex running on corn juice, his truck is as well.

If you have a nearly stock truck then I think it's only a tune away. Get into some mods you need to look into injectors, serious mods will have you searching for a fuel pump.

 

most none FF have injectors enough for pump gas and bolt ons. adding 30% on top of the stock injectors usually puts them over 100% idc.

 

mine is out of injectors and all i have is a cam

 

probably not an issue, but i thought i'd ask:

are the fuel lines the same for flex-fuel and non-flex? not the hard lines, but the soft hoses?

i know older cars have issues with the E85 eating the hoses. i bet gm just puts in a different tune, pump, and injectors, but who knows?

 

Thanks for the info guys.

I'm not sure GM even puts in a different pump. Might just be the injectors and the modification so that the computer will alter fueling based on fuel trims to determine ethanol content.

 

I suspect that the alcohol detection doesn't even function. We have e10 here pretty much year round but my command AF was always 14.68 when not in PE. Of course, I changed it to 14.10 a little while ago to get the correct ratio.

 

If you end up needing injectors, I have some Flex Fuel 36#'rs I pulled from a NNBS intake. Asking $100 OBO. These are my personal injectors, not sold through SDPC.

 

Factory flex trucks definitely get a different pump and injectors, and the tune to compensate. Everything else is likely the same though.
