I've been using a tactrix cable and romraider to put together a decent tune for an engine I'd like to use in my upcoming 818c project, and it has been going very well. My latest tune is for E85, and it has been a huge success. As much as I like running on E85, it is a pain to find fuel sometimes. The idea of roadtripping has me worried, too. I don't really want to run the tank down and flash to a 91 octane tune to go to Vegas..
Recently I've started looking at the Carberry rom, as it supports MANY really cool features like launch control, no lift to shift, dual maps without a reflash, speed density, and FLEX FUEL support. I've noticed many guys here are running E85, and I'm wondering if anyone else is diving into flex fuel.. By adding an ethanol sensor to the fuel system, the ecu can scale from standard 91/93 octane pump gas to E85 and any mixture in between. The idea of being able to road trip without worrying about finding corn fuel or being sure to completely empty the tank and reflash seems incredible. Once I get a carberry tune running on a spare ecu, I'm going to order the sensor to give it a try.
For anyone that's interested, check out the details on the Romraider site.

I'd really like to hear if anyone has had a stab at it.
