And the E85 tester that works by adding H2O only tell tells you what the CH3CH2OH content is, what is the rest? Do we need a flex fuel tester like the Zeitronix to go along with it?

 

No, it would go richer with less Ethanol, not leaner.

 

That depends on what's replacing the ethanol, no?

 

Of course, I was assuming gasoline.

 

Corrected my post to avoid confusion, thanks for those who pointed out the error.

 

I hate how inconsistent Ethanol can be. Here in NY I have to deal with "Winter Blend" and a greatly fluctuating Summer Blend too. Never ends. Thanks for the information tho!

 

David,

Don't you think it's still better to test the ethanol content by using the test tube than relying on the ECA?

 

The test tube we sell will tell you what the percentage is so you can be "safe" and know what you are getting.

The ECA from Zeitronix tells you the same thing without the hassle of the tube. The ECA also allows you to wire the input into an ECU and have the ECU change the calibration from pure ethanol to pure gasoline, so there is no worry of timing, fuel and boost needing to be changed at the content changes.

 

I will say i still want one for my car. also a little of topic but how do you guys test it at the gas station, pump it in to a gas can then put it in the tube or what?

 

Did you just show us in these videos that the ECA doesn't necessarily show the ethanol content of you fuel?

 

I always carry small plastic cup.but then again if I see that e85 is a **** I still fuel up cause I have no choice.just try using gas stations with decent e85 which I do.

 

Not easy or convenient to test at the gas station but what you said is what you have to do.
