i would want to run an ethanol content gauge similar to that the haltech set ups have. i sent him a message on his facebook and chatted some. no output for a gauge is available yet but he said once he sits down and works on coding some stuff he will have one

No need for a gauge. You can monitor ethanol content readings from the sensor with HPT or EFI Live. If tuned properly the car won't care what percentage of ethanol is in it if you have the fuel system to support higher levels of ethanol. You will see the vast majority of the gains with an E60 -E70 blend level though

I am in the middle of finishing my flex fuel setup. My sensor and fuel lines are made and
mounted. I need to pull off the other fender to do the wiring. I have pics if need but don't have a way to post. C5kids looks nice. My setup looks more hidden and factory. I have a bypass installed too to eliminate any restricion. Both ways look likey they would work well. It all comes down to preference. I can email my pics if someone wants to post them.

You can see mine displayed thru Dashlogic with DSTECK E85 mod......
TPS.....Timing
A/F.....Alcohol%
Mines setup from DSTECK when I hit my nitrous Alcohol % goes from 0% to 100% when activated

If you tune for E85 and then use E70 while it will be safe it will just go considerably richer nullifying most or all of the gains of running ethanol. But if you hook the sensor up then you can allow the PCM to adjust in any amount of timing at various engine speeds and loads according to the percentage of ethanol in the fuel.
HP Tuners allows the adjustment of the alcohol timing add table at different ethanol levels - allowing the use of max timing in the alcohol table at ratios above 80% only. Below that it can be adjusted between 50-80% at a fraction of that - let's say 65% or so of the actual timing applied when running at a ratio 80% or more.
So you can tune for all possible scenarios if the ethanol content is from 0-100% at any time

Either use a flex fuel sensor and allow the computer to adjust the timing based upon the % of alcohol content or don't both doing it at all IMO. But you would never tune for E70 and then use E85 because the car would go lean and BOOM

I've got a billet adapter in the works. No aftermarket fuel lines, no special tools, and a compact installation envelope. It will utilize 100% quick disconnect factory style connections and features an internal bleed line with a tap for a fuel pressure sensor. I'd share some snaps of the model but am concerned about people copying it, which is inevitable I suppose.
The thread I wrote has pretty much everything you need to know.
I build my own wiring harnesses for these. The CTS-V setup takes less than a minute to install. There's also no hard connections for wiring, just plug in and go.
And because I'm a ricer:
What ZBADESTZ had is different from an ethanol content sensor. It's a fake signal generator.
IMO, you guys are better off using the DashLogic display over a gauge. It's a hell of a lot cleaner. I can build them as it's just a matter of code, and I have a preset library for the displays I use, but using an existing display just makes more sense.

Here are some pics of my sensor install. I mounted it behind the drivers fender. It fit really well and I'm happy how it turned out.
