Flex fuel sensor and Kpro4

[Twisted-X]

So just out of curiosity (and future plans) which flex fuel sensors do Hondata recommend for Kpro4? Also, will the stock wideband O2 in a '05 Civic SI (EP3) work well enough or should I be looking at something a bit better (AEM, Etc.)?
Thanks

Nevermind, I found the info farther down. "Suitable sensors are GM part numbers 13577394, 13577379, and 13577429."
How about the O2 sensor?

The stock wideband should be pretty good. If you want to go aftermarket, we recommend the PLX Devices widebands.

Is it possible to use the flex fuel sensor on the supply line of a returnless system with Kpro4?

Yes, very easy. THis is how we do it on other platforms.

Great timing that this thread came up. :)
So GM 13577429 can go in between the fuel filter and fuel rail, correct?

correct
