Looks good. U thought this was a DIY on how to install a breathalyzer.... Guess I'll keep a searching. Lol

If you get caught enough the law will install one for you....

Lol. I honestly didn't know what a alcohol sensor was either.
I use the gas station right by my house pretty much every time. And I always put 93.

Understood, and thanks for the details. I figured most of this, but I am OCD with information and hate assuming. I am interested in how well this performs for you. Btw, clean install and well done on your homework.

Well I'm certainly no expert on this, but the guys at Manheim Hydraulic were horrified that I was considering running alcohol through a rubber hose. They had two scenarios for me:
One, that hose failure would mean spewing fuel right onto a hot engine with possible ensuing fireball
Two, that the reason the hose can fail is that the rubber is hardening and that you can end up with chips of it crumbling off and running down the line into your engine.
Whether either scenario is even possible, much less likely, I have no idea, but since they were going to have to get the hose fittings anyway, I was happy to take their word for it. Oh, and as a side note, I'm pretty sure they would have outright refused to do the job without making the line switch, they didn't have that "this is what we advise but we'll do whatever you want" face on... and given the crazy projects I've done in the past with their help, I'm familiar with that face.

Manheim Hydraulics parts list for the two fuel lines I had built:
3 BQFL08-6-6 3/8" Female Push-on x3/8 Fuelflex, $6.64 each
1 BQFL09-6-6 3/8" Female 90 Push-on x3/8 Fuelflex $9.35
2.6666 ft BQT10-FF 3/8 Fuelflex Tubing $1.62/ft, $4.32 total
4 BQFL-26 3/8" Fuelflex Clamp $.53 each, $2.12 total
4 AS06 3/8" Hose Assembly $1.5 each $6 total
PA sales tax on $41.71, $2.51
Total for the two pieces was $44.22 assembled
I think BNR is considering putting together a kit for this.

wiring harness is #20954434 i believe
Some more insight and I believe this is somewhere else on here

Yes, 20954434 is the wire harness part number. Cost was $50.28 from my local Buick dealer.

This is great
That's what I thought, too. I was wondering where he blew into it? LOL
I'd be interested in doing something like this to make my car flex-fuel capable.
I'd only want to do the bare minimum such as installing a sensor and possibly reprogramming the CM once so that I can put in whichever flavor of E0-85 is available at the moment, without impractical steps like reprogramming the car each time.
I don't want to spend a lot of money and effort on it, though, as this capability really isn't worth that much to me.

Contacted BNR and they asked me for a data log so they can take a look. Just got back from running a couple, one on eco and one on performance, we'll see what they say when they get back to me.
Also, ran a couple hundred pounds of swords and things up to Faire, 34 mpg at mostly 50mph, then back home empty, 44 mpg on same trip. These numbers are more or less typical of my pre-install numbers, if anything, that second number is higher than expected, so the install doesn't seem to have degraded performance.

I didn't expect any improvement, I was worried that somehow the install would degrade things, maybe mess with the ECM somehow, or interfere with fuel flow. Doesn't seem to be the case though.

The comp sensor arrived today
When the injectors and tune arrive I'm just going to run full e85 and take my time getting the sensor looped in.
One concern I have is that the sensor's original location on the CXL was right after the fuel tank, and we are installing it much closer to the intake.
On the CXL, the ECU likely lags the fuel/ign map adjustment when it senses a change in alcohol content to allow for the existing fuel mixture to be purged from the length of the fuel line.. A similar lag on the Sonic would mean the change in mixture would be combusting before the ECU made adjustments.
Does anyone think this should be a big concern?

It does, I thought they pointed that out in the post.

I imagine they figure all their customers will put it on the firewall and readjusted their table.
(Hope it was a more scientific approach than the post though)
Don't run it til the sensor is looped in, unless they activated that RIDICULOUS "estimation" map, your ECU won't know to run it differently.
(You'd want to have everything clarified as to how you were going to run to the tuner)
