^yup got most of it ready..
then i deleted the ****ing website (as crap as it is), and had to restore from... no not backups, from search the damn disk and manually piecing files together.. so mad...

Hey guys, I run FlexConverter.com. Im excited to finally have a full kit available and I think I was able to keep the price fairly reasonable as well!
As a rom developer myself (subaru), I realize how much work goes into adding features like this to the stock ecu code. Big thanks to David for making flex fuel possible on the EVO X! Im hoping my kit can make it that much easier to make the switch to flex fuel. Ive tuned a fair amount of cars on flex this past year and its a pretty amazing concept. Its awesome to simply drive up to a gas pump, pump a different fuel in, and drive away with 100+ more horsepower.
One snag that I did come across is that the AUDM EVO X doesn't have the fuel tank pressure connection like USDM cars. Because of this, my kit is USDM only right now. Im working on a simple solution for AUDM guys though so hopefully I can get that figured out soon.
@razorlab, I was able to tap into the evap purge valve 12v source for the plug-and-play. This worked out perfectly as this is an MFI relay switched 12v and its fairly close to the fuel pump sender. I use the fuel tank pressure sensor ground so as to have a clean sensor ground which reduces the possibility for voltage offset from the module to the ECU.
Thanks!
Jason

Got my new Flex Fuel harness. Thanks to Jason @ Flexconverter.com for sending it out so fast.
Now I can get the Ethanol sensor out of the engine bay, which will clean it up.

If you are on a tephra V2 ROM it's $50, if you are on a vanilla or V1 tephra ROM its $100 per his website. What you need to do is PayPal him the money and in the notes state the year and model (MR/GSR) and the VIN for the car so he can encode the ROM for your specific car. You'll then receive the ROM and an associated XML in your email within a day or two typically.
Please do the RA next. This is all I am really waiting on.
^ soon
... actually can you email a stock version of 56920008?
I just sent the first 53050012 (2008-2010 EDM/AUDM MR) out, so hopefully that will be ready for primetime soon
edit - I just sent out the first 56890013 (2011 USDM GSR) out as well...
so, need to work out whats next, i am actually thinking a RA rom... keep our cousins happy (A bit :P)

Is his PayPal just "tephra"? Or is his email available? Could not find it on the website. And once I get the items mentioned above after the payment what other hardware is required to get the full flex fuel capabilities, sorry really new at this and I am aware a tune is required. Please let me know any information that would benefitial to a rookie. Thank you so much!
Also make sure you include the VIN of your car and if it is a GSR or MR because they are different ROM's.
Flexconverter.com has a plug and play kit for the Evo X that makes flex conversion simple with V3.
