E85 guys, ethanol content LCD display group buy
 

-------------------------------------------------------------------------------

Displays have been shipped to everyone. Here is the datasheet that describes the connections:

I'd recommend making sure the brightness is set how you want it before you get it all buttoned up


------------------------------------------------------------------------------


A bunch of people have asked me how I did my ethanol content LCD display. It uses a GM fuel composition sensor and a custom display a company designed and built for me. The company is in Serbia so the shipping sucks. I made a post on EvoM offering to order some more if people want them, so I'm offering it up here too. I'm not making any money on it, just helping people that want them get them..

You have to get your own GM sensor from ebay/junkyard/etc for the display to work

Here is the datasheet describing it: http://workspace.wamnet.com/~gryan/fuel%20monitor.pdf

This is it in my car:

If 5 people want them, its $152 per display + $32 shipping
If 10 people want them, its $147 per display + $19 shipping

Standard backlight color is yellow/green, can get whatever color you want for $8 more.

Just copy/paste the list with your name added if you want one

edit - just a clarification -
This doesn't include a 0-5V analog output, it's just a gauge

Re: E85 guys, ethanol content LCD display group buy
 

This is a fantastic idea for a device. Congrats on getting it made! Hopefully these will still be available in summer?

Re: E85 guys, ethanol content LCD display group buy
 

Where did you put your sensor? I may be interested.

Re: E85 guys, ethanol content LCD display group buy
 

I put my sensor along my fuel return line mounted in the engine bay by the vehicle info plate on the firewall. It's around the size of two packs of smokes with two metal tubes coming off the top of it to connect your fuel lines to. Thats on an Evo but I think it would be pretty easy to find a spot for it on any car.

Re: E85 guys, ethanol content LCD display group buy
 

What vehicles carry the sensor we would need?
I am interested in this.

Re: E85 guys, ethanol content LCD display group buy
 

These are the ones I know about, any GM Flex-Fuel vehicle should have one I think. I got mine off a 2001 2.2L Sonoma

  • 2.2L Chevrolet S-10 pickup 2WD
  • 2.2L Sonoma GMC pickup 2WD
• 2002
  • 5.3L V-8 engine Chevy Silverado� and GMC Sierra� half-ton pickups 2WD & 4WD
  • 5.3L Vortec-engine Suburban, Tahoe, Yukon and Yukon XLs

Re: E85 guys, ethanol content LCD display group buy
 

I can get them any time it's just that the shipping is really expensive if it's not split between a number of people. It's somewhere around $100 to ship just one from Serbia to the states

Re: E85 guys, ethanol content LCD display group buy
 

Looks like Ebay FTW, i am down for one of these.
when i see you get person #4, i will put my name down

Re: E85 guys, ethanol content LCD display group buy
 

I would be in for one next spring.

Re: E85 guys, ethanol content LCD display group buy
 

I'm down if we can get 10. I don't need it that bad and every penny I'd save the better.

Re: E85 guys, ethanol content LCD display group buy
 

Thats pretty cool. I would think with all the new rage around E85 you could sell the crap out of these. I may want one in spring as well.

Re: E85 guys, ethanol content LCD display group buy
 

Could you please post up a picture of yours mounted if you have one.

You can add my name to the list if you'd like, but I am only in if we make it to 10 people. C'mon ya bastdards, sign up!

Also, what other colors are there for the display? Do they have a simple like Black backround with red digits? Kind of like my Apexi turbo timer, and PLX wideband displays? I'd prefer that if possible because those backlit ones with black digits seem hard to read sometimes when it's really bright out.

Re: E85 guys, ethanol content LCD display group buy
 

First off that display looks great in your car. I'm planning on going e85, but in all honesty, I wouldn't know what to do if the readings were abnormal. I mean don't you have to be able to pretty much tune your own car in order to benefit from knowing the ethanol content?

Re: E85 guys, ethanol content LCD display group buy
 

What are you using to tune with 98GSX? If you have some knowledge on tuning your own car, that would be very beneficial.

Re: E85 guys, ethanol content LCD display group buy
 

dsmlink, I understand HOW to do stuff with it, like I know where to go to find different settings. But I don't know how to tune a car. I've just never been taught. I tried reading up on dsmlink.com for a while, but it was a little advanced and overwhelming for me. I'd love to learn, I just haven't found anybody that could teach me.

Re: E85 guys, ethanol content LCD display group buy
 

This is it in my car

http://workspace.wamnet.com/~gryan/ethgauge2.jpg

It's really useful if you can tune your own car, when it changes I know to log the car and see if the tune needs to be brushed up before I rip on it. As I tweak the tune I save a copy and then can just load that tune up according to the display.

I think one of the things holding people back from signing up is getting a hold of a GM fuel sensor. I grabbed mine off ebay for $100 in the spring. I've seen them go for anywhere between $80 and $250 on Ebay for used/new ones. Finding a wrecked flex-fuel truck would be the best. Or if you are a baller you could just order a new one from gmpartsdirect.com for $360.

I also have a signal converter on mine that outputs a 0-5V analog signal, hoping to get that working with a hacked Evo9 ecu rom to alter boost/fuel/timing based on the Eth % like the new Saab turbos do. I can get the signal converter boxes too, they are $120ish

Re: E85 guys, ethanol content LCD display group buy
 

I am in the same boat as B-man. 10 and i am in.

Re: E85 guys, ethanol content LCD display group buy
 

3 for that one.

Re: E85 guys, ethanol content LCD display group buy
 

If some one can get me a sensor for $100, I will take one.

Re: E85 guys, ethanol content LCD display group buy
 

Me too.

Re: E85 guys, ethanol content LCD display group buy
 

i think we have to come to the conclusion that we need these things to be cheaper somehow.

Re: E85 guys, ethanol content LCD display group buy
 

Get them made in China. IS there any other company out there doing this?

Re: E85 guys, ethanol content LCD display group buy
 

I think Mo has India's phone number.

Re: E85 guys, ethanol content LCD display group buy
 

So you have 3 on your list, and you have 3 (me, Brownman, User Name) that are all in if you can get it to 10. That means 4 more people...

Is there a "due date" for this? I'm sure we can get 10 people to sign up for this, may just take another 2 weeks.

And let me know about the colors.

Re: E85 guys, ethanol content LCD display group buy
 

I agree. I want one but its not in my budget right now.

Re: E85 guys, ethanol content LCD display group buy
 

No due date, I dont think the people that are currently on the list are in a big rush and I havent posted an "order date" yet. I was half thinking letting this sit for a month or so. I emailed them for some more info on custom colors, I'll let ya know what I get back

Re: E85 guys, ethanol content LCD display group buy
 

Sounds good. Thanks

Re: E85 guys, ethanol content LCD display group buy
 

Here's the info I got back about the backlight color:

Backlight panel on 1 x 16 characters display works with four LED diodes. Two
diodes are on the left side of the display and other two are on the right
side. Diodes glow into a piece of plastic, size of plastic is identical to
the display size and the plastic is perforated on the top side where it
touches the display panel. These perforations works like small prism and
they enable the light to exit the plastic and go through the display.
Factory LED's inside are green but the problem is that the lcd panel also
performs as a weak green filter. This color of the lcd panel occurs due to
the two polarizing filters. Another problem is that space for the LED's
inside is around 1.5mm (0.1 inch) and if leds are any other color than green
they must be much brighter in order to go through LCD system. Changing the
leds with others of different color is not a problem, stock colors are
green, yellow, blue, red orange and white, white will however pull to the
green color due to basic green color of the LCD.



So basically any color there is an LED for which should be just about anything you could want.

Re: E85 guys, ethanol content LCD display group buy
 

So it sounds like they can't actually make the numbers illuminate red, and just have a black backround, correct? Thanks for the info, and if that is the case then I suppose I'll just stick with the normal green like yours is.

Re: E85 guys, ethanol content LCD display group buy
 

Well there are 5 people now, I'm going to leave it a bit longer for anyone else that wants to jump in, then I'll collect money and order.

Re: E85 guys, ethanol content LCD display group buy
 

if i can be in the 10 people discount, then i will take one in blue.

Re: E85 guys, ethanol content LCD display group buy
 

k, so if one more person signs up I can get them at the 10 people price. so close

Re: E85 guys, ethanol content LCD display group buy
 

Ok we got 7 so I added the three of you that wanted in if it was 10 total.

Please paypal $166 (or $174 if you ordered a color) to rgrice@gmail.com

Please include your name as I have you on this list in the paypal!

Other people can still get in

Thanks

Re: E85 guys, ethanol content LCD display group buy
 

so if i didn't want a color, it would be the same as yours?

Fuck it, i am getting blue, gonna hop on paypal now.

Re: E85 guys, ethanol content LCD display group buy
 

Okay, count me in too.

Re: E85 guys, ethanol content LCD display group buy
 

Putting in the order for these today, if you havent paid please paypal me asap if you still want one or I gotta drop you

Re: E85 guys, ethanol content LCD display group buy
 

Shit sorry it took me so long. Money is sent for just a normal green one just like yours, thanks!

Re: E85 guys, ethanol content LCD display group buy
 

So whats the word on these?
Anyone find a sensor yet, i can't find shit.

Re: E85 guys, ethanol content LCD display group buy
 

No luck with that junkyard response I forwarded to you? Bummer. The order is in with the electronics place, I'll check in with how its going.

Re: E85 guys, ethanol content LCD display group buy
 

no, i emailed them and no response, so i left it for a bit and tried again, still nothing.
