What management systems have flex sensor?
You can use stock systems.
There have been a few people that have used it over on the HPTuners forum.
I was going to put one in my car but I have too many other things in the works.
One of the credentials is an E38 or E40 ECM, DBW throttle body and the correct harness.
Then, you just need the stock GM sensor and mount it on the fuel return line.
The programming is simple to do with HPtuners as well.

E38 and E40 PCM's do it as well as the 0411 PCM. There are couple operating systems for 0411 PCM's that support the flex fuel sensor. The problem is that they stop at 2 bar SD tuning for 0411 PCM's. So if you arent doing this to an fbody or going big boost, you've got options

Haltech S2000 does it with a nice 8 channel EGT setup it makes tuning the car a bit easier. it has quite a few nice features I'm most interested in the integrated boost and alchy control so I can have one tranny do it all
I also want to try the PCS paddle shift setup with a standalone computer for the RPM 4L65e tranny

From personal experience and the import scene, Pro-Efi is a great one but not very user friendly. I had one installed on my 2JZ setup but never got to tuning the project before it was canned. However, all of my friends in the Supra scene run them and I have personally seen the capabilities.
AEM Infinity is great as well and a bit more user friendly. Also has a feature for remote tuning that has been useful after the initial tune in case the tuner needs to tweek things from a distance.
Syvec units are great but I only know of one person using them near me. Its a stunning piece for the price but the issue is local tuners. Syvec also has the remote tune capabilities which was used by the one dude I am referring to. Haltech is a good unit but from my observations (which I have very little tuning knowledge, I leave it to the experts) it is not as robust as the Pro-Efi or AEM.
Still too new into the GM scene to know anything HP related or the such. Hope that helps a wee bit.

Pretty much any ecu can be remotely tuned. In as much as when tuning requires a laptop, you have access to a good internet connection, and the remote aspect is simply remote control of the laptop.
IMO, unless there are competent guys at each end...it's a risky proposition though
Link/Vipec are another that fairly sure can make use of the flex fuel sensor.

Running e70 when you tune for e85 isnt as dangerous as the internet makes it out to be. As long as you dont run a really hot plug and dont throw a bunch of crazy timing at it, you wont hurt anything.
