Diablo E85

Post by claytonmx »

So I am wanting to install the flex fuel conversion kit on my truck that is already Tuned by Lew. Once I install it, is it possible with the Diablo to be able to then have a tune made for my truck with E85 even though the truck initially doesn't support it? Or would I need to use HPTuners or something else?

Truck - 2017 GMC Sierra 1500 SLT 6.2l 8 speed.

you could have a tune made with more timing to take advantage of the e85.

Clayton...

I do not tune for e85... Once the custom tuning process is done/complete - which was done a year ago - then you could use e85 again if you want, ONLY IF your truck is a factory flex fuel vehicle - which it is not... and you do get worse mileage with e85, so you'd be filling up more often, not really saving anything...

BUT -- since your truck is not a factory flex fuel vehicle, -- you'd need to add a flex fuel sensor, bigger injectors, and bigger, higher-flowing fuel pump... because e85 requires more fuel -- it requires larger fuel injectors and a higher flowing pump to use E85. Because more fuel is being used to achieve the same effect as normal gasoline... E85 does not atomize and ignite as easily as normal gas, so it requires about 30% more fuel/fuel flow than regular gas to achieve the same power.

And that is not something I would/can tune for via an email tune...

Hes adding a system that handles the fueling, so he would just need a tune for timing, like a race gas tune.
