Why Fitronic when only very small amount tuner can tune that thing? Especiaaly for an 8 when you can rewired the flex fuel sensor to the ECU? I just don't like to be limit it to a certain amount tuner that why I was asking why

The reason I want to go that route is because the display can literally monitor almost everything evoscan can monitor , also the 3 tuners who can tune it are the best in the business from what I’ve read and gathered

It is not the fitronic the issue. You can buy ANY Ethanol content sensor with a 5v output, such as AEM or Zeitronix and wire it to the ECU. It can be wired to the alt map switch pin and logged in evoscan. Although the issue remains that the few that have the rom+definition for the flexfuel options are selling it only. And if you buy it, that does not give you the definition so you can play with it and learn it yourself. I have done flexfuel on tephraxmod v3 and it is fairly simple, tune a pump gas map, tune an E85 map and enabling the flexfuel will do the rest.

The kit itself with the fuel hoses runs about $750. Add an extra $500 to get the flex fuel tune, I was given the option to pay for the tune after paying for the kit or with the kit, I just paid for it all at once at about $1,250.

I understand but as I mention for Evo 8 there's no need to fitronic, I wire and 5vdc to the ECU to be able to log in evoscan. I know for EVO IX the rom definition are not available which is kind of sad unless you get a standalone. Anyway for Evo 8 the rom definition are available, my Evo is running on flex fuel
