FlexFuel kit recommendation?

[wrath]

I just bought a brand new Civic SI. I also have a dodge Challenger with a FlexFuel kit, it's a plug-and-play piggyback module and I can use any combination of E85 and 93 premium in the tank. it's great because E85 is 2.49 a gallon here.

But they don't make the same kit for the Honda. I don't want to tune it only to E85, I want to be able to switch back and fourth if I need to. (Although cheap, there's only a couple of stations with E85 here). Plus I don't want to permanently alter the ECU as the car is still under warranty.

Anyone here run a FF kit on their car? and if so, does the engine tolerate E85 well?

That's the Hondata kit, I wanna say you'll still need to flash the Hondata flex fuel tune, but not sure. Just be careful tuning the SI on flex fuel, it's super easy to blow these engines up if you don't build them properly.

Yea I definitely don't want to blow the head gasket lol. I'm not planning on racing it or driving it hard. it's more for the fuel cost savings. I drive a lot for work so this would save money in the long run
