on a real fast look - that list appears to be the entire Chev/Gmc list of FFV's. All the later ones have no sensor to my knowlege and instead simply use an algorithm to read trims and other data to guess what you put in the tank- that is the way my company 3.5L Impalas do it.

Instead look for the S10- I have one of those (a 2001 2.2L FFV) which has an honest to God sensor in it that still works just fine after 10 years. It and the Sonoma were about the only ones I know for sure in that list that has the real sensor but perhaps someone else here knows if the real early (pre-2004) 5.3L's used them- I believe they might have.

Automakers dropped the idea of using the sensor due to it's cost and having watched Chrysler do fine without. Not sure what year Ford stopped using them but the '05 Taurus in our Fleet does not have one- early ones did. Will the Zeitronix kit work with a Ford sensor?

I wished I still knew where the list of vehicles that had these sensors in them was so I could post it up- i'll look but not sure if I can find it- been about 2 years since that discussion

Edit- here is some info;

Unfortunately one of the old links was broken and for the life of me I cannot recall where we discussed the cut-off dates on Ford and GM models. You might want to call a dealer for that info.

 

Have any of you seen an electric all in one tester? Id like something that we can test drums with easily. Thanks in advance. -Chad

 

A $1 funnel makes flex fuel sensor and ECA all in one sampling tester.

 

I've seen some on the internet, but they're lab equipment and cost several thousand dollars.

 

A lot of GM dealerships use the Kent-Moore unit. It needs to be kept calibrated (not difficult) and it is very critical to follow the sample proceedure exactly- I have seen dealerships come up with very bad numbers (too high of alcohol) from leaving the sample on the machine too long.

Most guys racing just do the water phase separation test but it is not super accurate.

Try developing a relationship with the station manager so he will share his load manifests with you which would normally state the gallons of gas vs ethanol.

 

I love my Zeitronix ECA. Takes the time & guess work from using test tubes. Though I never had to do that

Dont mind the ERror read out, I just barely hooked it up when this picture was taken

That's a great caged Zeitronix ECA installation. You really just look at the gauge once, after a fill up.

 

looks nice that sensor i want one !!!

 

Yea this will be my next modification!! How easy is the install i was looking at your install thread (https://www.evolutionm.net/forums/al...iewed-ttp.html) and was confused about the fuel lines that u hook up. Do u have a better diagram of exactly what needs to be done?

 

Not correct unless that blender wants to get in huge trouble with the EPA. I'm in the ethanol industry and blend rates for E85 are randomly audited by the EPA so I highly doubt a blender would be willing to risk it; E85 spec says between 70-85% ethanol. Even our denaturant inclusion rate is monitored (2%). With that said, anything is possible I suppose.

 

There's several stations here in Colorado that get above 90% in the summer. There's one station that runs around 90% year around.

 

I'm using a sensor out of a 2000 Taurus. It works great. The Zeitronix plug does not fit, I had to get one from Ford. Got the sensor for $50. The inlet and outlet lines are different from the GM sensors, but that worked out better for my location in my car.

Here is the vehicle list I used to search for a sensor:

i have a question about how much fuel you can flow threw the gm or ford flex sensor? my car makes over 700hp and would that sensor even flow enough for my setup?

 

For a modern fuel injected engine, the sensor is normally placed in the return line that goes back to the fuel tank. This way it shouldn't restrict the fuel flow to your engine.
