ELI5 Ethanol sensor

[CarTramrod]

Beyond piece of mind what is the purpose of an ethanol sensor? Can tuners make the tune adjust on its own based on ethanol?

With PCMtec, yes​

So what do you hook the sensor up to for it to communicate to the car that it needs to adjust for the ethanol content? Is this used more on turbo cars than supercharged cars since it's not as easy to change your boost ?

turbo/supercharged/na doesn't matter

it's about changing the octane of your fuel not your boost

So I already have the sensor and I will be making the fuel lines around the sensor and motion raceworks bracket. Where do I get that control box and the wiring for it. I cant find where to actually buy they kit only places that sell tunes for it.

The Zeitronix ECA-2 CAN is what you need to integrate the ethanol sensor to the CAN bus so the PCMTEC Custom OS flex fuel logic can work properly. Then you need a tuner who can enable that logic so it adjusts for ethanol content.

If you’re looking for a kit, I’m only familiar with one or two on the market. You can put your own system together that will work with the PCMTEC Custom OS based on the info available on the forums and from your tuner of choice.

Anyone looking to make their own converter to keep prices down simply needs to emulate the Zeitronix CAN packet structure and it will be plug and play. No one has done it at scale as the volume is too low, however it is absolutely doable.
