Excellent job. What happen if I replace the existing pump with a fuel flex pump. Again congratulations for you good job. Tks

[@alecaagaard]

you would still need this sensor, no matter what pump is in the vehicle.

just like in real life hahahaha, badass video man! I like the way you used the factory wiring to your advantage, never seen that before, definitely gonna try and do something like that

[@alecaagaard]

Glad you found it helpful, that factory wiring trick is badass.

The odds I stumbled across this video… do you happen to know what pcm your truck has p59?

[@alecaagaard]

Lol, the algorithm knows what's good! 🤪 Yes I have a p59, just gotta swap the OS to a flex fuel.

[@bubah5723]

What all did you have to change in the tune?

[@alecaagaard]

You need to swap the truck to a flex fuel operating system. Once you do that, nothing, aside from traditional fueling, timing and other tuning changes.
