It's possible. It'd need custom coding. The OFT tunes as they are right now are, as far as I know, using all the original code just with tweaked maps.

This is correct. But OFT being opensource, if we had coders and tuners write it out, it would be very possible to use flex fuel systems. Sadly I lack in both coding and tuning skills sufficient or I would be working on this already.

as @Celadrielas stated, it really is a BLAST tuning your own vehicle. I went from complete tuning novice to elementary maf scaling student in a month with the help of reading and researching the resources of this site.

10 flashes and about 20 or so logs later, I have a car that outperforms the OTS v2.06 map (which wasnt bad! The Grimmspeed intake really threw a wrench in the maf scale, though) and it is a BLAST to drive.

Getting rid of that ridiculous cold start noise was satisfying too. All able to be done with Romraider and OFT.

hahaha This is where I am at with the damn AEM intake. I took out the chip it comes with and.... yuck.... but with it in, I am a LOT closer.

That is my latest datalog (if OP wants to see them) and it's a work in progress, as I am still seeing potential knock when getting onto a freeway.
